Use of masks in public places in Poland during SARS-Cov-2 epidemic: a covert observational study.

BACKGROUND: Face masks have been employed in the COVID-19 pandemic plans as a public and personal health control measure against the spread of SARS-CoV-2. In Poland, obligatory wearing of masks in public spaces was introduced on April 10th, 2020; a relaxation of previous universal measures was announced on May 29th, 2020, limiting use to indoor public places. OBJECTIVE: To assess use of masks or other protective devices in public spaces in Poland during the SARS-Cov-2 epidemic. METHODS: A non-participatory covert observational study was conducted on three dates, (10.05/18.05/25.05.2020) at public spaces in 13 regions with different risks. Ten consecutive individuals were observed by each of 82 medical students (n = 2460 observations), using a structured checklist. RESULTS: Among 2353 observed persons, the female/male ratios were 1.0, 1.1, and 1.0 on the three dates. Almost three quarters - 73.6% (n = 552/750) were using masks on date 1, 66.5% (544/818) on date 2; and 65.7% (516/785) on date 3. Cloth masks predominated on all dates (64.7-62.3%-62.6%), followed by medical (23.4-28.5%-26.9%). Being female (OR = 1.77-1.47-1.53 respectively) and location in a closed space (OR = 2.60-2.59-2.32) were each associated with higher usage. Participants in sports were about two times less likely to use masks (OR = 0.64-0.53-0.53) as compared to other activities. The proportion using masks correctly decreased gradually over time (364/552; 65.9%; 339/544; 62.3% and 304/516; 58.9%). More females wore masks correctly (date 1: 205/294; 69.7% vs 159/258; 61.6%, and date 3: 186/284; 65.5% vs 118/232; 50.9%; p = 0.045; p = 0.0008 respectively). Uncovered noses (47.3-52.7%) and masks around the neck (39.2-42.6%) were the most frequent incorrect practices. CONCLUSIONS: Practices were not in line with official recommendations, especially among males, and deteriorated over time. Cloth masks were predominantly used in public spaces. Health promotion, through utilizing all available communication channels, would be helpful to increase compliance.

Vaccination concerns, beliefs and practices among Ukrainian migrants in Poland: a qualitative study.

BACKGROUND: Ukrainians numbering approximately 1.2 million are the largest migrant group in Poland. Data on vaccination coverage among migrants are not collected in EU, including Poland. Therefore, this qualitative study aimed to identify vaccination practices in this migrant group, to explore facilitators and barriers to vaccination and related access to Polish healthcare services. METHODS: In September 2019, a qualitative study of Ukrainian migrants (UMs) living in Szczecin, Poland, and recruited through a snowball sampling method, was conducted. Using a semi-structured topic guide, four focus groups were held with 22 UMs aged 18-45. Participants were asked about their attitudes towards vaccination in general with comparison between services in Poland and Ukraine. Following transcription and translation, a thematic analysis was conducted. RESULTS: Respondents were distrustful of Ukrainian vaccination policy, medical personnel and individual vaccines, however, they often returned to Ukraine for dental and gynaecological appoint-ments. While critical with regards to registering with Polish GPs practices, UMs were confident in health professionals, as well as vaccine delivery. Vaccines were perceived as safer and of better quality than in Ukraine. Difficulties in translating vaccination records were rarely reported, verbal communi-cation was not problematic due to language similarities. All UM parents reported vaccinating their children according to the Polish schedule. However, a significant number of adult UMs have not completed mandatory vaccinations, although they may have obtained false immunization certificates; according to UMs those can be obtained by bribing. Participants reported lower acceptance of the influenza vaccine, mainly due to perceptions around its importance; none had been vaccinated against influenza. None of UMs had heard of the HPV vaccine. UMs experienced challenges in accessing credible online vaccination information in Ukrainian, no official local health authority vaccination material existed either, except for information about measles. CONCLUSIONS: This study pinpointed positive UM attitudes and practices regarding child vaccination in the Polish healthcare system and identified issues for improvement, such as adult vaccination. Health communication should be more tailored within UMs information delivery systems to enable migrants to make informed choices about vaccination. Further research is needed to better assess factors affecting vaccine uptake identified in this study.

Seroprevalence of anti-HBc, risk factors of occupationally acquired HBV infection and HBV vaccination among hospital staff in Poland: a multicenter study.

BACKGROUND: Due to numerous blood exposures hospital staff are at risk of acquiring hepatitis B virus (HBV) infections. This study aimed at estimating prevalence of HBV, associated risk factors and HBV vaccination among Polish health care workers (HCWs). METHODS: A cross-sectional sero-survey was conducted (October 2016-January 2018) in 10 randomly selected hospitals from two provinces: of low and high incidence of HBV, with the use of an anonymous, self- administered questionnaire. Blood samples were screened for hepatitis B core antibodies (anti-HBc) with enzyme immunoassay. RESULTS: Of the 306 participating HCWs, 88.6% were females, 69.9% nurses (mean age 47.8 ± 9.0 years). HBV vaccination was reported by 94.2%, participants (4.7% with 2 doses, 58.1% with 3 doses, 37.2% took a booster), but of these 75.1% reported no post-immunization serology. The sero-prevalence of anti-HBc was 12.1% (95%CI 8.4-15.7%); only 11.1% had ever screened themselves for HBV infection. Out of 37 anti-HBc positive HCWs, 29 reported being vaccinated for HBV; 10.5% vaccinated HCWs were anti-HBc positive. Regarding other occupational risk factors, 27.8% had experienced a sharp injury (SI) in the last year, 80.0% of incidents were not reported. The use of safety devices (SD) was 86.3%; 35.9% participants used to recap a needle. Older age (OR = 4.24), lack of HBV vaccination (OR = 7.42), working at the province of high HBV incidence in the general population (OR = 2.69) were each predictors of participant's HBV infection. CONCLUSIONS: High anti-HBc seroprevalence was found in hospital staff with older generation particularly constituting a risk group. Unsatisfactory vaccination coverage and the use of SDs, needle recapping and under-reporting of SIs were main modifiable risk factors regarding HBV infection. The study provides evidence of the protective role of HBV vaccine, as well as the possible effect of HBV incidence in the general population on HCW's anti-HBc seropositivity. Universal vaccination, followed by strict policies to confirm immunity, better compliance with infection-control practices and widespread implementation of SDs should be enforced to protect hospital staff from occupationally acquired HBV infections.

[Risk of occupational exposure to blood-borne pathogens in paramedics]. / Ryzyko ekspozycji zawodowej na patogeny krwiopochodne u ratowników medycznych.

Paramedics constitute a group of professionals who are constantly exposed to potentially infectious biological material through frequent and close contact with patients, possibly resulting in occupationally acquired infections. The paper's objective has been to assess the occupational risk regarding blood-borne infections and identify preventive measures used among paramedics worldwide, on the basis of the related literature review. The literature search, covering the period 1987-2017, was performed using PubMed, Elsevier, Springer and Google Scholar databases. A comparative analysis of blood exposure was conducted and the report of such events and the use of personal protective equipment among paramedics in Poland and other countries worldwide was developed. The data on occupational blood exposures among paramedics is sparse. The resulting comparisons obtained in various scientific studies are difficult due to diverse data collection methods, influencing the resulting consistency. Additionally, there were some methodological errors found in previously published studies, such as selection bias. The percentage rate of paramedics exposed to blood in the last 12 months varies from 22% in the USA to 63% in Thailand; in Poland that rate fluctuates widely, ranging between 14-78%. Paramedics are frequently exposed to blood while performing their duties, but almost 50% of paramedics do not report any exposure which is mitigated by the systematic use of personal protective equipment: gloves are regularly used by 53-98% of paramedics, masks and goggles are worn by 33-62% of them. This fact puts the paramedics group at risk of blood-borne infections. Therefore, there is an urgent need to conduct further, methodologically correct, multi-center studies to accurately assess occupational blood exposure in paramedics. Med Pr 2018;69(6):685-694.

[Selected risk factors for occupational exposures to blood-borne pathogens in cosmetics salons]. / Wybrane czynniki ryzyka ekspozycji zawodowych na patogeny krwiopochodne w salonach kosmetologicznych.

BACKGROUND: Services offered in the esthetic/beauty industry poses the risk of blood-borne infections (BBIs) due to carrying out invasive procedures. The study objective: was to assess the number of sharps injuries, occupational risk factors, and preventive methods used among cosmetologists. MATERIAL AND METHODS: The anonymous survey was conducted (February-April 2017) in randomly selected beauty/esthetic medicine clinics in Szczecin, Poland; 96 cosmetologists were invited. RESULTS: Eighty cosmetologists (83.3%), responded. The mean age of the group was 25 years (range: 20-60 years). The majority of the respondents (95%) used sharps while at work, 41.3% had suffered at least one sharps injury during their occupational career. Clippers were the most common injury-causing instrument (39.4%), and manicure/pedicure was the most common injury-causing procedure (51.5%); 84.8% of injuries were not reported. The number of injuries was associated with age (34.9% in the group of 20-29 years old respondents vs. 64.7% in respondents ≥ 30 years old, p = 0.05), work experience (32.6% in the respondents working for 1-3 years vs. 68.8%, in those working ≥ 7 years, p = 0.03), and working hours/week (28.9% in those working ≤ 40 h vs. 57.1% of those working > 40 h, p = 0.02). Needle recapping was reported by 47.5% of respondents, 13.8% did not dispose used needles into a container, 17.5% did not routinely use gloves. CONCLUSIONS: Cosmetologists are at risk of sharps injuries. Inconsistent use of preventive methods and failure to report incidents may result in contracting BBIs. There is a need to implement education and intervention measures to prevent occupational injuries, particularly with regard to cosmetologists aged over 30 years, with a longer professional experience, working over 40 h/week.

A cross-sectional sero-survey on preoperative HBV vaccination policy in Poland.

BACKGROUND: A two-dose preoperative vaccination schedule against HBV has been the widely accepted policy in Poland. However, its effectiveness has not yet been assessed. OBJECTIVE: To evaluate a two-dose preoperative HBV vaccination policy by an assessment of the proportion of patients who don't present a protective level of anti-HBs (<10.0 mIU/ml). METHODS: Consecutive patients from surgical/gynecologic wards of 12 randomly selected hospitals in West Pomerania, Poland, hospitalized between 2010 and 2013, vaccinated against HBV with a two-dose regimen, were asked to complete an anonymous questionnaire. Serum samples were assayed for anti-HBs with the use of third-generation testing methods. To compare sensitivity versus specificity across a range of values for the ability to predict a dichotomous outcome (a protection against HBV infection) a Receiver operating characteristic (ROC) curve was determined. RESULTS: There were 193 patients, 58.5% women, median age 52 years. Almost a half (46.0%) of the patients were operated on within 0-60 days of taking the second vaccine dose, 16.2% - 61-180 days after, 37.8% >180 days after. Anti-HBs titer was below a protective level in 49.2% of participants (0.0 mIU/ml in 17.8%, 0.1-9.9 mIU/ml in 31.4%); none of them were aware of this fact. Age ≤ 52 years (OR = 1.89) and having surgery more than 37.5 days after HBV vaccination (OR = 2.70) were associated with greater odds of being protected against HBV infection through vaccination. For the time frame between the second dose implementation and surgery 23 days, a sensitivity of 84% and specificity of 22% for obtaining protection against HBV infection was found, for the time frame >37.5 days - sensitivity remained high (80%), while specificity increased (41%); there was an apparent peek on the ROC curve between 38 and 60 day. In the group vaccinated 0-37.5 days before surgery, less patients had the protective level of anti-HBs titer than in vaccinated 38-60 days before surgery (32.3% vs 60.0%; p = 0.03). CONCLUSIONS: The success rate in achieving adequate immune protection with two dose HBV vaccination schedule in preoperatively vaccinated patients is relatively low, especially among those vaccinated less than five weeks prior to surgery. In more than a third of cases the standard three-dose regimen could have been implemented, as participants had time to complete a third dose. Current recommendations regarding a preoperative policy with a 2-dose vaccination schedule in Poland should be revised; the best time to perform surgery after the implementation of the second dose of vaccine in the context of patient protection against HBV infection would be between 38 and 60 days.

[HBV, HCV, and HIV infection prevalence among prison staff in the light of occupational risk factors]. / Wystepowanie zakazen HBV, HCV i HIV wsród personelu wieziennego w swietle zawodowych czynników ryzyka.

BACKGROUND: Objectives of the study: to assess the occupational risk for blood-borne infections (BBIs) among prison staff (number/ circumstances of blood exposures and preventive methods used), and to estimate the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). MATERIAL AND METHODS: The survey, which included serological testing with the use of 3-generation enzyme-linked immunosorbent assays (ELISA) was completed on active staff at a correctional facility in Goleniów, Poland, between June-July 2015. RESULTS: Response rate was 38%, 87 participants (aged 22-64 years, median: 34 years) agreed to participate. There were 88.5% males, correctional officers comprised 87.4% of the participants. Having had ≥ 1 blood exposure during professional career was reported by 28.7% respondents, 8% - sustained it in the preceding year. For correctional officers the last blood exposure was caused by a hollow-bore needle/razor blade during cell or manual searches. This was not reported by 83.3%. Participation rate in an infection control training was 85.1%. Hepatitis B virus vaccination uptake was 83.9%. Compliance with glove use was 75.9%, with protective eyewear - 28.7%. Regular use of both was reported by 9.2% of participants. The lack of their availability was the most common reason (79.7%) for non-compliance. Anti-HBc (hepatitis B core antigen) total/anti-HCV/anti-HIV prevalence was 2.3%, 1.1%, and 0%, respectively. CONCLUSIONS: Prison staff are at risk for occupational exposures to blood. Reporting of such incidents is poor, as well as compliance with personal protective equipment use, which place them at risk for acquiring BBIs. Anti-HCV prevalence is similar to that observed in the general population, anti-HBc total prevalence is lower, possibly due to high vaccination uptake, however, poor response rate limits precise prevalence estimates.

Concerns related to CCR5 gene delta 32 mutation role in hepatitis B virus infection

STUDY OBJECTIVE: A literature review to analyze potential evidence regarding the influence of Δ32 CCR5 gene mutation on resistance to/clinical recovery from HBV infection METHODS: Literature search, covering the period 1996-2017, was performed using Medline. Comparative between-studies analysis was conducted with regard to reliability as well as statistical and clinical significance of results RESULTS: Data on the influence of Δ32 CCR5 mutation on the course of HBV infection are sparse and results obtained in various scientific studies are not consistent. As the example, heterozygosity for CCR5/CCR5Δ32 in healthy Iranian blood donors was greater than in cases with chronic HBV infection; in the American study on Caucasian subjects who had been infected with HBV CCR5 Δ32 reduced the risk of developing a persistent HBV infection by nearly half. Conversely, the Indian study revealed that heterozygosity for CCR5/CCR5Δ32 was more often present in patients with chronic hepatitis B than in healthy controls. However, there were some methodological errors found in previously published studies such as limited sample size and/or incorrect selection of controls; this could influence the fact that results were not heterogeneous CONCLUSIONS: The evidence for potential association of CCR5 gene Δ32 mutation on HBV infection in regard to the resistance to HBV infection or recovery from an HBV infection are insufficient. Previously conducted studies presented the lack of results' consistency, possibly due to between-population differences in the context of genetic determinants, ethnic and geographical origin, as well as methodological errors. There is an urgent need to conduct further, methodologically correct studies on larger populations from different regions, including Polish subjects

Prevalence of HBV Infection and Knowledge of Hepatitis B Among Patients Attending Primary Care Clinics in Poland.

It is well known that community awareness of hepatitis B (HB) can lead to vaccination and testing. The study objectives were to assess the prevalence of HBV infection and knowledge of HB among adult patients attending randomly selected primary care clinics. A cross-sectional sero-survey was conducted in March 2013 in the Zgorzelec region, Poland, with the use of an investigator-developed questionnaire containing 22 questions regarding HB knowledge. Serum samples were assayed for anti-HBc total and anti-HBs with enzyme immunoassay. The prevalence of anti-HBc total among 410 participants (median age 56 years) was 10.3 % (95 % CI 7.6-13.8 %), nobody was aware of an infection. The main sources of HB knowledge were the media and medical staff. The mean knowledge score was 14.8 ± 4.9; 76.7 % of the respondents had scores >50 %. Particular gaps were detected relating to knowledge of unprotected sexual intercourse and MTCT; 45.6 % patients were not aware of the potential asymptomatic course of HBV infection, 41.2 % about chronic HB treatment. A patient's low educational level was negatively associated with a high knowledge level; the willingness for further education on HB and HBV vaccination in the past were independently associated with good knowledge. In conclusion, the HBV infection remains a public health threat in Poland, since the prevalence of infection markers in asymptomatic adult patients was high. Knowledge gaps call for awareness campaigns which may increase testing and diagnosis, audiences representing lower education level should be targeted first. Knowledge on HB might serve as an effective tool in decision making regarding vaccination.

Zika--an emerging infectious disease. The risk assessment from Polish perspective.

In the last years, attention has been paid to Zika virus (ZIKV) infection, the emerging vector-borne disease. It is responsible for major outbreaks in Africa, Asia and, more recently, in previously infection-naïve territories of the Pacific area, South America and Caribbean. The etiology, epidemiology, transmission, and clinical manifestations of ZIKV disease are discussed, along with the diagnostic possibilities in the aim to assessing the risk of its introduction to Poland. ZIKV is spread by Aedes mosquitoes which are not found throughout Poland. The prevention strategies adopted by national public health authorities should be based on a surveillance of imported cases and on increasing awareness among healthcare professionals and travelers. Due to a large number of asymptomatic ZIKV infections and limitations in the availability of diagnostic tests, monitoring based on laboratory results is likely to be unreliable in Poland. There are no requirements to report ZIKV infections to the European Centre for Disease Prevention and Control. Nevertheless, the global epidemic continues to spread, and despite travels of Poles to countries in which Aedes mosquitoes are active, Polish sportsmen will be travelling to Brazil in August 2016 to participate in the Olympic Games, the will also be true of the many fans who will follow them; therefore imported cases of ZIKV infection are possible. As the awareness of the infection risk will increase among medical staff and travelers, the number of suspected cases of travel-related ZIKV infections may rise in Poland. Medical staff should be informed where and how to report such cases. Thorough surveillance, adequate assessment of possible threats, action plans, rapid and effective intervention development, spread of up to date information of ZIKV, as well as other emerging or re-emerging infectious pathogens can play a key role in guaranteeing population health.

Zika virus intrauterine infections from the obstetrician's perspective.

Zika virus (ZIKAV) infections could potentially occur in Poland due to international travel made by its nationals to regions where the Aedes mosquito is active. A causal relationship between prenatal ZIKAV infection and microcephaly and other serious brain anomalies has been found due to the time association between the infection in pregnancy and a presence of congenital nervous system malformations, together with the detectable pathogen in amniotic fluid and fetus's tissues. Two ZIKAV infection cases of pregnant women who were diagnosed with fetal microcephaly in the state of Paraiba, Brazil, later described in Ultrasound Obstetrics and Gynecology by Oliveira Mello et al. are discussed, in the context of the possible introduction of ZIKAV into Poland and the role the obstetrician should play in the detection and rapid reaction to potential threats. According to recommendations of international agencies for disease control and prevention, Polish obstetricians who take care of pregnant women and of those planning to become pregnant in the nearest future, and declaring travels to areas of the Aedes mosquito activity, should advise their patients to consider postponing travel or if they must travel, to take necessary precautionary measures to avoid mosquito bites. Pregnant women who have travelled to areas with ZIKAV transmission, or whose male partners had travelled to such areas and returned in the period of their female part-ner's pregnancy, should be monitored appropriately in the context of congenital abnormalities, including microcephaly.

A cross-sectional serosurvey on hepatitis B vaccination uptake among adult patients from GP practices in a region of South-West Poland.

BACKGROUND: Hepatitis B is a significant health burden in Poland with nosocomial transmission being the main source of infection. Therefore, HBV vaccination is widely recommended for those not covered by the national immunisation program. OBJECTIVE: To assess the coverage and influencing determinants of HBV vaccination among adult patients attending GP clinics as well as to establish serological status in terms of HBV infection. METHODS: Patients who were seen consecutively in March 2013 at four randomly selected GP practices located in Zgorzelec county, in south-western part of Poland, were invited to participate and complete questionnaires on socio-demographic data and other factors related to vaccination. A pilot study was done in one urban GP practice in the city of Gryfino (Gryfino county), the results have been included in the study. Patients' immunisation status was assessed basing on vaccination cards and anti-HBs titer with the use of third-generation testing methods. In addition, serum samples were assayed for anti-HBc total. RESULTS: Response rate: 99.3 %. Of 410 participants (66.1 % females, median age 56 years), 55.4 % (95%CI:50.5-60.1 %) were previously vaccinated; in those 11.5 % took 2 doses, 66.1 % - 3 doses,18.1 % - 4 doses. Elective surgery was the main reason (57.7 %) for HBV immunization, 4.8 % - were vaccinated due to recommendations by GPs. The multivariable logistic regression model revealed that living in a city (OR 2.11), and having a surgery in the past (OR 2.73) were each associated with greater odds of being vaccinated. Anti-HBc total prevalence among those unvaccinated was 13.6 % (95%CI:9.3 %-19,5 %), and 7.2 % (95%CI:4.4-11.8 %) among those vaccinated. CONCLUSIONS: Low HBV immunization coverage among adult patients from GP clinics and the presence of serological markers of HBV infection among both - those unvaccinated and vaccinated call for comprehensive preventative measures against infection, including greater involvement of family doctors. Although interventions should cover the whole population, inhabitants living in the rural areas should be a group of special interest. Preoperative immunization for HBV seems to be an efficient public health tool to increase the vaccination uptake.

Evaluation of human papilloma virus (HPV) vaccination strategies and vaccination coverage in adolescent girls worldwide.

STUDY OBJECTIVE: An analysis of HPV vaccination strategies and vaccination coverage in adolescent girls worldwide for the last eight years with regard to potential improvement of vaccination coverage rates in Poland. METHODS: Literature search, covering the period 2006-2014, was performed using Medline. Comparative analysis of HPV vaccination strategies and coverage between Poland and other countries worldwide was conducted. RESULTS: In the last eight years, a number of countries introduced HPV vaccination for adolescent girls to their national immunization programmes. Vaccination strategies differ, consequently affecting vaccination coverage, ranging from several percent to more than 90%. Usually, there are also disparities at national level. The highest HPV vaccination coverage rates are observed in countries where vaccines are administered in school settings and funded from the national budget. Poland is one of the eight EU countries where HPV vaccination has not been introduced to mandatory immunization programme and where paid vaccination is only provided in primary health care settings. HPV vaccination coverage in adolescent girls is estimated at 7.5-10%. CONCLUSIONS: Disparities in HPV vaccination coverage rates in adolescent girls worldwide may be due to different strategies of vaccination implementation between countries. Having compared to other countries, the low HPV vaccination coverage in Polish adolescent girls may result from the lack of funding at national level and the fact that vaccines are administered in a primary health care setting. A multidimensional approach, involving the engagement of primary health care and school personnel as well as financial assistance of government at national and local level and the implementation of media campaigns, particularly in regions with high incidence of cervical cancer, could result in an increase of HPV vaccination coverage rates in Poland.

Concerns of occupational HIV infection among surgical Staff in the light of anti-HIV sero-status and the distribution of Δ32 allele of the CCR5 gene: a cross-sectional study.

UNLABELLED: Surgical staff might be considered at most risk of accidental viral infection due to their higher exposure to blood. AIM: To evaluate surgical staff concerns about occupational HIV infection, to determine contributing factors, to assess their sero-status regarding this pathogen, and the frequency of the Δ32 allele of the CCR5 gene. METHODS: With the use of a self-administered anonymous questionnaire a cross-sectional sero-survey was conducted from February 2009-January 2010 among doctors/nurses from the surgical/ gynaecological wards of 16 randomly selected hospitals in Western Pomerania, Poland. Fear level was measured by the use of the VAS scale (range 0-10). Serum samples were tested by ELISA. Genotyping was performed using a PCR-AFLP assay. RESULTS: Response rate 84.9%; 427 participants, 88.3% females; 84.8% nurses, 15.2% doctors (median age 42 years, range 22-61 years). More than two thirds of respondents (67.2%) overestimated HIV single exposure risk. The median level of occupational HIV fear was 6.67. The prevalence of anti-HIV was 0.0% (95%CI: 0-0.9%); 1.2% (95%CI: 0.5%-2.9%) of participants were homozygotes Δ32/Δ32. The stepwise regression model revealed that job category (nurse) was associated with HIV fear (p<0.001). CONCLUSIONS: The risk of contracting occupational HIV infection remains low; no anti-HIV positive individuals were found among surgical staff, one in one hundred were resistant to HIV infection. Staff members, especially nurses, were much concerned with acquiring an occupational HIV infection, possibly due to the lack of knowledge on single exposure risk. Educational actions and better access to specialists which would help surgical staff in managing anxiety at the workplace is urgently needed.

[Etiological, epidemiological and clinical aspects of coronavirus infection MERS-CoV]. / Etiologiczne, epidemiologiczne i kliniczne aspekty zakazenia koronawirusem MERS-CoV.

All medical staff and travellers to the Arabian Peninsula should be aware of a new epidemic caused by Middle East respiratory syndrome coronavirus (MERS-CoV), which has emerged in the Arabian Peninsula (2012), secondary cases have been seen in Africa, Europe, Asia and the United States. It seems likely that the outbreak will continue with sporadic adventive cases occurring outside the Middle East, including Poland. Polish medical literature on MERS-CoV is rather scant. Therefore, the article describes etiology, epidemiology, symptoms and diagnostic methods of MERS-CoV infection which are available in Poland. Selected cases of patients infected with MERS-CoV are also presented followed by preventive methods. Comparisons between MERS-CoV and SARS-CoV are briefly described. Epidemiological and genetic studies point at zoonotic transmission of MERS-CoV from camels and possibly bats. Infection is characterized by severe acute respiratory failure with a high fatality rate and the ability to spread from person to person; health care-associated outbreaks have been described. No known vaccine or antiviral therapy has been developed for MERS. The diagnosis is made by demonstrating the MERS-CoV in lower respiratory secretions by RT PCR. General hygiene measures such as regular hand washing before and after touching animals and avoiding contact with sick animals in the epidemic areas, should be adhered to. Health-care workers should always apply standard precautions consistently with all patients, regardless of their diagnosis due to non-specific symptoms of MERS-CoV in the early stage of infection.

John Snow and cholera--the bicentenary of birth.

The bicentenary of John Snow's birth, a legend in his field, for his research on epidemiology and the prevention ofcholera, constitutes a unique opportunity to commemorate this iconic figure. In the article, his spectacular achievements in this discipline are presented, including his epidemiological investigation during cholera epidemic and the well-known Broad Street intervention in Soho, in 1854, as well as his methodologically elegant experiment "on the grandest scale" in which he compared the cholera fatality rates in households served by two different water supply companies. Having referred to Snow's research, the cholera outbreak in Haiti in 2010 is also discussed.

Knowledge and preventive practices regarding COVID-19 disease among Ukrainian refugees in Poland.

Russia's invasion of Ukraine contributed one of the largest migration movements in the 21st century. Refugees may become a source of severe acute respiratory syndrome coronavirus 2 infections for the residents of host countries. The study aim was to assess knowledge and preventive practices regarding coronavirus disease 2019 (COVID-19) among Ukrainian refugees in Poland. The cross-sectional study was conducted between March and April 2022 among Ukrainian refugees registering consecutively in Zielona Góra, Poland. Knowledge and preventive practices were assessed by giving 1 point for each correct answer by anonymous, self-administered questionnaire. The response rate was 96%, 190 participated (mean age 37.8 ±â€…15.5 years; 57.9% females); 61.6% self-reported their socio-economic status (SES) as high, 38.9% reported high level of education. The mean COVID-19 knowledge score was 3.06 ±â€…1.95; 19.5% scored >50%. The knowledge level was higher among migrants with high SES (P = .003). The mean preventive practices score was 2.56 ±â€…1.38; 54.0% scored ≥ 60%. 40.5% declared social distancing, 62.6% followed coughing etiquette, 69.0% home isolate themselves during COVID-19. 57.9% always used masks in public space, however 74.2% wore masks with uncovered nose. Refugees with higher education, high SES and knowledge level had significantly greater preventive practices scores (P = .002; P = .02; P = .03, respectively). The knowledge and preventive practices level was insufficient. Educational campaigns oriented to raising knowledge and prevention behavior skills should be implemented, especially targeting high-risk groups to avoid spread of COVID-19.

"Why would we?" A qualitative study on COVID-19 vaccination decision making among Ukrainian economic female migrants in Poland.

Background: Ukraine has one of the lowest COVID-19 vaccination rates in Europe. This may pose a significant epidemiological risk in the context of the refugee crisis and the fact that, since 2020, SARS-CoV-2 has been spreading and changing globally. Objective: To evaluate determinants of vaccination decision making among Ukrainian female migrants (UFMs). Methods: A qualitative study with 45 UFMs was conducted between December 2021 and January 2022. UFMs, from 2 Polish provinces, differing in age, education and length of stay were invited with the use of the snowball technique. Using a semi-structured topic guide, eight focus groups were conducted in person, recorded and transcribed. Thematic, qualitative analysis was made; key themes which emerged from the data (with the help of the Working Group Determinants of Vaccine Hesitancy Matrix), were related to contextual, individual/group and contextual vaccine/vaccination-specific influences. Results: Mothers were found to be playing a crucial role in children and adolescent COVID-19 vaccine decision-making process. Universal trust in the Polish healthcare system and vaccination procedures, employer requirements and willingness to preserve jobs, desire to get back to normal and social influences were paramount prerequisites to let UFMs make a decision to get vaccinated. However, COVID-19 vaccines also faced backlash among UFMs. Negative experiences with vaccines provided in Ukraine, doubts about the rapid vaccine development, combined with lack of confidence in vaccine safety, specifically regarding child vaccination, might have a bearing on UFMs' decision about declining COVID-19 vaccine while on migration. Discrimination through HCWs during vaccination visits was also reported. Corrupted Ukrainian healthcare system, which facilitates proof forgery regarding vaccination certificates, could act as a negative influencer of UFMs' vaccine decision-making. Conclusion: The results provide the novel information, expressed in economic UFMs' own words. Findings show that influencers of the decision-making process regarding the COVID-19 vaccination are complex and polarized; elements of hesitancy may persist after migration. Any continuation of UFMs' vaccination with COVID-19 vaccine should be subject to designing accessible information to address modifiable demotivators of the vaccine decision-making process identified in this study.

[Attitudes of medical specialists toward HBV, HCV or HIV infected surgical staff and a sero-survey among staff members]. / Postawy personelu medycznego wobec osób zakazonych HBV, HCV lub HIV pracujacych w oddzialach zabiegowych oraz badania serologiczne pracowników.

BACKGROUND: Issues regarding the transmission of blood-borne viruses from infected medical personnel to patients are controversial to both parties. The aim of this study was to evaluate the attitudes towards disclosure of HBV/HCV/HIV-infected surgeons and the possibility of being forced to give up surgical procedures, as well as to assess the prevalence of anti-HBc total, HBsAg, anti-HCV and anti-HIV in surgical staff. MATERIAL AND METHODS: Using an anonymous questionnaire a cross-sectional sero-survey was conducted among surgeons and nurses of surgical wards in 16 randomly selected hospitals, Western Pomerania, Poland, from January to June 2009. Serum samples were tested for anti-HBc, HBsAg, anti-HCV and anti-HIV by ELISA tests. RESULTS: In the group of 427 participants (232 nurses, 65 doctors; a median age: 42 years), anti-HBc was found in 16.6%, HBsAg in 0.7%, anti-HCV in 1.4% and anti-HIV in 0%. The risk of a single exposure to HBV was correctly defined by 26.5% of participants, to HCV by 19.7%, to HIV by 18.7%. 16.2% participants stated that infected surgeons should disclose their HBV, HCV, or HIV serostatus, 39.8% and 42.6% that those HBV/HCV-infected and HIV-infected, respectively, should discontinue practicing surgery. Participants who correctly assessed the risk of contracting HIV/HBV/HCV after a single exposure were significantly (p = 0.0001; p = 0.03; p = 0.01, respectively) less likely to favor infected staff being forced to discontinue surgical procedures. CONCLUSIONS: A fraction of surgical staff showed detectable markers of HBV/HCV infection, they may be a source of infection for operated patients. Surgical staff's knowledge about occupational blood exposure risk was not satisfactory, which might have influenced the restrictive attitudes to force those infected with HBV/HCV/HIV to give up surgical procedures and a willingness to disclose their serological status.

[Assessment of occupational exposure to HBV, HCV and HIV in gynecologic and obstetric staff]. / Ocena zawodowego narazenia na zakazenie HBV, HCV i HIV u personelu oddzialow ginekologii i poloznictwa.

BACKGROUND: The aim of the study was to assess the occupational risk for hepatitis B, C and HIV in gynecologic and obstetric staff in the context of the number of sharps injuries, HBV immunization coverage, compliance with personal protective equipment (PPE) use and reporting of exposures. METHODS: A voluntary anonymous survey was carried out between January-June 2009 in 15 ran domly selected hospitals in West Pomerania, Poland. RESULTS: There were 110 participants (response rate 72%), 88.2% females, 11.8 males (aged 21-60 years; mean, 42 years); 80.9% nurses, 19.1% doctors. Among those 60.9% reported at least one sharps injury in the preceding year (Me = 1, range 1-12), 43.6% worked at least once a year with a recent abrasion or cut on their hands. The respondents reported the most recent injuries being caused by a hollow-bore needle (54.4%), a suture needle (26.5%), and an instrument (19.1%); 82.5% of such incidents went unreported. Compliance with PPE use was high for glove use (92.7%), much lower for protective eyewear (28.7%). Except one participant who reported acute symptomatic hepatitis B in the past (possibly due to previous surgery), all participants reported being immunized with HBV vaccine: 46.8%--took three doses, 48.6%-- a booster and 4.6% ended the regimen on two doses. CONCLUSIONS: Frequent sharps injuries, mostly unreported, work with unprotected recent abrasion or hands' cuts and lack of compliance with PPE use are important risk factors contributing to occupational HBV, HCV and HIV infections among gynecologic and obstetric staff. The risk of HBV infection has been significantly reduced by a complete immunization coverage observed among participants.
