RESUMO

The study objectives were to assess bromate concentrations in bottled drinking water sold at retail in Kuwait and assess pH values relationship to bromate concentrations. A cross-sectional study was conducted in 2019 where 120 bottled water samples were collected from supermarkets across six governorates in Kuwait. Samples represented local brands that used distilled or mineral water as well as imported brands that used mineral water only. The samples were analyzed for bromate concentrations and pH values. The overall mean bromate concentration was 4.02 µg/L (95% CI: 3.35-4.69) with concentration of 4.45 µg/L in locally distilled water significantly (P < 0.05) higher than that in imported mineral water samples (i.e., 1.34 µg/L). The overall bromate percent positive was 41.7% (n = 120) with 35.8% in locally distilled samples, significantly higher than that in imported mineral samples (5.8%). None of the local mineral bottled water samples had detectable bromate. Bromate concentrations in our samples were within the international allowable limits of less than 10 µg bromate/L (except for one local distilled sample that contained 14.9 µg bromate/L). The mean pH value was 7.39 (95% CI: 7.33-7.45). There was no significant relationship between pH values and bromate concentrations in our samples. Our findings proved that local and imported bottled water sold at retail in Kuwait was bromate safe.

RESUMO

One thousand four hundred ninety-one Salmonella isolates recovered from retail foods including chicken, beef, fish, pork, dumplings, and cold dishes in China in 2007, 2008, 2010, 2011, and 2012 were analyzed for distribution of serotype and antimicrobial susceptibility. A total of 129 Salmonella serotypes were detected among 1491 isolates. Salmonella Enteritidis (21.5%), Typhimurium (11.0%), Indiana (10.8%), Thompson (5.4%), Derby (5.1%), Agona (3.8%), and Shubra (3.0%) were the seven most important serotypes in 1491 isolates. For antibiotic susceptibility, except 16 (1.1%) isolates were susceptible to all tested antibiotics, 131 (8.8%) resisted 1-2 and 1344 (90.1%) resisted three or more antibiotics. One thousand forty-six (70.2%) of 1491 Salmonella isolates were identified as multidrug-resistant (MDR) isolates, which could resist three or more categories of antibiotics. Resistance to sulfisoxazole (78.1%) was most common among the tested Salmonella, followed by tetracycline (70.6%), trimethoprim/sulfamethoxazole (68.0%), and nalidixic acid (63.4%). Resistances to amikacin (20.0%), levofloxacin (18.7%), gatifloxacin (17.9%), ceftriaxone (17.7%), and cefoxitin (13.2%) were less frequently detected. Resistance to fluoroquinolones was most common among Salmonella Shubra and Indiana isolates, while resistance to cephalosporins was frequently detected among Salmonella Thompson isolates. The results highlighted the diversity of Salmonella serotypes and the high prevalence of Salmonella MDR isolates in China. Compared with Salmonella Enteritidis and Typhimurium isolates, the higher fluoroquinolones and cephalosporins resistance rates of some individual serotypes (Salmonella Shubra, Indiana, and Thompson) also provided more information for further study related to fluoroquinolones or cephalosporin-resistant Salmonella.

RESUMO

During the past century, the microbiological safety of the US food supply has improved; however, many foodborne illnesses and outbreaks occur annually. Hence, opportunities for the food industry to improve the safety of both domestic and imported food exist through the adoption of risk-based preventive measures. Challenging food safety issues that are on the horizon include demographic changes to a population whose immune system is more susceptible to foodborne and opportunistic pathogens, climate changes that will shift where food is produced, and consumers' preferences for raw and minimally processed foods. Increased environmental and product testing and anonymous data sharing by the food industry with the public health community would aid in identifying system weaknesses and enabling more targeted corrective and preventive actions. Clinicians will continue to play a major role in reducing foodborne illnesses by diagnosing and reporting cases and in helping to educate the consumer about food safety practices.

RESUMO

Yellow Fever (YF) is an acute viral hemorrhagic disease. Uganda is located within the Africa YF belt. Between 2019 and 2022, the Ugandan Health Authorities reported at least one outbreak of YF annually with an estimated 892 suspected cases, on average per year. The persistent recurrence of this disease raises significant concerns about the efficacy of current response strategies and prevention approaches. YF has been recognized as a One Health issue due to its interrelatedness with the animal and environmental domains. Monkeys have been recognized as the virus primary reservoir. The YF virus is transmitted through bites of infected Aedes or Haemagogus species mosquitoes between monkeys and humans. Human activities, monkey health, and environmental health issues (e.g., climate change and land use) impact YF incidence in Uganda. Additionally, disease control programs for other tropical diseases, such as mosquitoes control programs for malaria, impact YF incidence.This review adopts the One Health approach to highlight the limitations in the existing segmented YF control and prevention strategies in Uganda, including the limited health sector surveillance, the geographically localized outbreak response efforts, the lack of a comprehensive vaccination program, the limited collaboration and communication among relevant national and international agencies, and the inadequate vector control practices. Through a One Health approach, we propose establishing a YF elimination taskforce. This taskforce would oversee coordination of YF elimination initiatives, including implementing a comprehensive surveillance system, conducting mass YF vaccination campaigns, integrating mosquito management strategies, and enhancing risk communication. It is anticipated that adopting the One Health approach will reduce the risk of YF incidence and outbreaks.

RESUMO

Food safety remains a significant global public health concern, with the risk of unsafe food varying worldwide. The economies of several low- and middle-income countries (LMICs) heavily rely on livestock, posing a challenge to ensuring the production of safe food. This review discusses our understanding of pre-harvest critical issues related to food safety in LMICs, specifically focusing on animal-derived food. In LMICs, food safety regulations are weak and inadequately enforced, primarily concentrating on the formal market despite a substantial portion of the food sector being dominated by informal markets. Key critical issues at the farm level include animal health, a low level of good agriculture practices, and the misuse of antimicrobials. Effectively addressing foodborne diseases requires a comprehensive One Health framework. Unfortunately, the application of the One Health approach to tackle food safety issues is notably limited in LMICs. In conclusion, considering that most animal-source foods from LMICs are marketed through informal channels, food safety legislation and policies need to account for this context. Interventions aimed at reducing foodborne bacterial pathogens at the farm level should be scalable, and there should be strong advocacy for the proper implementation of pre-harvest interventions through a One Health approach.

RESUMO

A growing niche in the locally grown food movement is the small-scale production of broiler chickens using the pasture-raised poultry production model. Limited research exists that focuses on Salmonella and Campylobacter contamination in the environment associated with on-farm processing of pasture-raised broilers. The objective of this study was to establish data relative to Salmonella and Campylobacter prevalence and concentration in soil and mortality compost resulting from prior processing waste disposal in the small-scale, on-farm broiler processing environment. Salmonella and Campylobacter concentrations were determined in soil (n = 42), compost (n = 39), and processing wastewater (PWW; n = 46) samples from 4 small broiler farms using a 3-tube most probable number (MPN) method for Salmonella and direct plating method for Campylobacter. Salmonella prevalence and concentration (mean log10 MPN per sample weight or volume) in soil [60%, 0.97 (95% CI: 0.66 to 1.27)], compost [64%, 0.95 (95% CI: 0.66 to 1.24)], and wastewater [48%, 1.29 (95% CI: 0.87 to 1.71)] were not significantly different (P > 0.05). Although Campylobacter prevalence was not significantly different by sample type (64.3, 64.3, and 45.7% in soil, compost, and PWW, respectively), the concentration (mean log10 cfu) of this pathogen was significantly lower (P < 0.05) in wastewater [2.19 (95% CI: 0.36 to 3.03)] samples compared with soil [3.08 (95% CI: 2.23 to 3.94)], and compost [3.83 (95% CI: 2.71 to 4.95)]. These data provide insight into small-scale poultry production waste disposal practices and provides a record of data that may serve as a guide for future improvement of these practices. Further research is needed regarding the small-scale broiler production environment in relation to improving disposal of processing waste for optimum control of human pathogens.

RESUMO

We sought to assess pre-vaccination and post-vaccination seroprevalences of anti-SARS-CoV-2 antibodies in Kuwait and to compare antibody levels between vaccine types. In phase 1 (pre-vaccination period, n = 19,363), blood samples were collected before the launch of COVID-19 vaccination in Kuwait between 1 September and 31 December 2020. Blood samples for phase 2 (post-vaccination period, n = 4973) were collected between 1 September and 30 November 2021. We tested subjects for anti-SARS-CoV-2 antibodies using the DiaSorin LIAISON® SARS-CoV-2 IgM and Trimeric S IgG tests. In the pre-vaccination period, the prevalence of SARS-CoV-2 IgM and IgG was 14.50% (95% CI: 14.01-15.00) and 24.89% (95% CI: 24.29-25.50), respectively. The trend of seropositivity increased with age and was higher for females and non-Kuwaiti participants (p < 0.0001). Interestingly, seroprevalence was significantly higher for those who had received one dose of BNT162b2 (95.21%) than those who had received one dose of ChAdOx1-nCov-19 (92.86%). In addition, those who reported receiving two doses had higher seroprevalence, 96.25%, 95.86%, and 94.93% for ChA-dOx1-nCov-19/AstraZeneca, mix-and-match, and BNT162b2 recipients, respectively. After the second dose, median spike-specific responses showed no significant difference between ChAdOx1-nCov-19 and BNT162b2. Furthermore, statistical analysis showed no significant difference between median anti-trimeric S antibody levels of vaccinated individuals according to sex, age, or nationality (p > 0.05). In contrast, a negative correlation between age and anti-trimeric S IgG titers of BNT162b2-vaccinated subjects was observed (r = -0.062, p = 0.0009). Antibody levels decreased with time after vaccination with both vaccines. Our findings indicate that seroprevalence was very low during the pre-vaccination period (25%) in the general population and was greater than 95% in the vaccinated population in Kuwait. Furthermore, ChAdOx1-nCov-19 and BNT162b2 are effective in generating a similar humoral response.

RESUMO

Introduction: The study objective was to compare the prevalence of antimicrobial resistance (AMR) in clinical Escherichia coli and Pseudomonas aeruginosa isolates obtained from a secondary-care hospital prior to and during the COVID-19 pandemic in Kuwait. Methods: A retrospective descriptive study was conducted based on AMR profiles of clinical Escherichia coli and Pseudomonas aeruginosa isolates. The AMR data represented isolates from five specimen types (body fluids; blood; respiratory; wound, bone, or other tissues; and urine) of patients admitted to four wards (surgical, medical, pediatric, and maternal-postnatal). Tested isolates between January 2019 and February 2020 represented the pre-COVID-19 pandemic period in Kuwait, whereas those from February 2020 until April 2021 represented the 'during COVID-19' period. Results: A total of 1,303 isolates (57.2% E. coli and 42.8% P. aeruginosa) were analyzed. For ceftazidime, ertapenem and meropenem, the prevalence of AMR in E. coli was significantly (p<0.05) lower in pre-COVID-19 wards compared to that during COVID-19, whereas for other antibiotics (i.e., cefepime, gentamicin, and trimethoprim/sulfamethoxazole), the prevalence of AMR in pre-COVID-19 was significantly higher than that during COVID-19. The prevalence of AMR to gentamicin in P. aeruginosa isolates from non-COVID-19 wards (52.8%) was significantly higher (p<0.001) than that from COVID-19 wards (35.0%) and from the pre-COVID-19 period (32.9%). The multidrug-resistance (MDR) prevalence was 37.4% for E. coli and 32.1% for P. aeruginosa isolates. The odds of MDR in E. coli isolates from the COVID-19 medical wards were significantly lower (OR=0.27, [95%CI: 0.09-0.80], p=0.018) compared to the pre-COVID-19 wards. The odds of MDR E. coli and P. aeruginosa isolates by COVID-19 status stratified by specimen type were not different (p>0.05). Conclusions: No major differences in AMR in E. coli and P. aeruginosa prevalence by specimen type and wards prior to and during the COVID-19 pandemic was observed at this hospital. The high reported MDR prevalence calls for better infection control and prevention.

RESUMO

ABSTRACT: Vibrio cholerae can cause pandemic cholera in humans. The bacterium resides in aquatic environments worldwide. Continuous testing of V. cholerae contamination in water and aquatic products is imperative for food safety control and human health. In this study, a rapid and visualized method was developed for the first time based on loop-mediated isothermal amplification (LAMP) for detection of the important virulence-related genes ace, zot, cri, and nanH for toxins and the infectious process of V. cholerae. Three pairs of molecular probes targeting each of these genes were designed and synthesized. The one-step LAMP reaction was conducted at 65°C for 40 min. Positive results were inspected by the production of a light green color under visible light or green fluorescence under UV light (302 nm). Limit of detection of the LAMP method ranged from 1.85 to 2.06 pg per reaction of genomic DNA or 2.50 × 100 to 4.00 × 102 CFU per reaction for target genes of cell culture of V. cholerae, which was more sensitive than standard PCR. Inclusivity and exclusivity of the LAMP method were 100% for all target genes. The method showed similar high efficiency to a certain extent in rapid testing of spiked or collected specimens of water and aquatic products. Target genes were detected by absence from all water samples from various sources. However, high occurrences of the nanH gene were observed in intestinal samples derived from four species of fish and one species of shellfish, indicating a risk of potentially toxic V. cholerae in commonly consumed aquatic products. The results in this study provide a potential tool for rapid and visualized detection of V. cholerae in water and aquatic products.

RESUMO

OBJECTIVE: The actual impact of the pandemic on COVID-19 specific mortality is still unclear due to the variability in access to diagnostic tools. This study aimed to estimate the excess all-cause mortality in Iran until September 2021 based on the national death statistics. RESULTS: The autoregressive integrated moving average was used to predict seasonal all-cause death in Iran (R-squared = 0.45). We observed a 38.8% (95% confidence interval (CI) 29.7%-40.1%) rise in the all-cause mortality from 22 June 2020 to 21 June 2021. The excess all-cause mortality per 100,000 population were 178.86 (95% CI 137.2-220.5, M:F ratio = 1.3) with 49.1% of these excess deaths due to COVID-19. Comparison of spring 2019 and spring 2021 revealed that the highest percent increase in mortality was among men aged 65-69 years old (77%) and women aged 60-64 years old (86.8%). Moreover, the excess mortality among 31 provinces of Iran ranged from 109.7 (Hormozgan) to 273.2 (East-Azerbaijan) per 100,000 population. In conclusion, there was a significant rise in all-cause mortality during the pandemic. Since COVID-19 fatality explains about half of this rise, the increase in other causes of death and underestimation in reported data should be concerned by further studies.

RESUMO

BACKGROUND: Electronic health record (EHR) has emerged as a backbone health care organization that aims to integrate health care records and automate clinical workflow. With the adoption of the eHealth care system, health information communication technologies and EHRs are offering significant health care advantages in the form of error reduction, improved communication, and patient satisfaction. OBJECTIVE: This study aimed to (1) investigate factors associated with physicians' EHR adoption status and prevalence of EHRs in Kuwait and (2) identify factors predicting physician satisfaction with EHRs in public hospitals in Kuwait. METHODS: This study was conducted at Kuwait's public Al-Jahra hospital from May to September 2019, using quantitative research methods. Primary data were gathered via questionnaires distributed among 295 physicians recruited using convenience sampling. Data were analyzed in SPSS using descriptive, bivariate, and multivariate linear regression, adjusted for demographics. RESULTS: Results of the study revealed that the controlled variable of gender (ß=-.197; P=.02) along with explanatory variables, such as training quality (ß=.068; P=.005), perception of barriers (ß=-.107; P=.04), and effect on physician (ß=.521; P<.001) have a significant statistical relationship with physicians' EHR adoption status. Furthermore, findings also suggested that controlled variables of gender (ß=-.193; P=.02), education (ß=-.164; P=.03), effect on physician (ß=.417; P<.001), and level of ease of use (ß=.254; P<.001) are significant predictors of the degree of physician satisfaction with the EHR system. CONCLUSIONS: The findings of this study had significant managerial and practical implications for creating an inductive environment for the acceptance of EHR systems across a broad spectrum of health care system in Kuwait.

RESUMO

Salmonella is a major cause of foodborne disease outbreaks worldwide, mainly through poultry. Recently, there has been an increase in multidrug-resistant (MDR) Salmonella infections globally. The increased drug resistance results in increased costs and poorer health outcomes due to unavailability or delayed treatment. This study aims to determine the prevalence of Salmonella in retail raw chicken meat and identify their antimicrobial resistance profiles. A total of 270 retail raw chicken carcasses (local and imported) were collected from three hypermarket chains in Qatar between November 2017 and April 2018. Thirty carcasses were contaminated with Salmonella (11.11%). The prevalence of Salmonella in locally produced chicken was higher than in imported chicken (OR = 2.56, 95% CI: 1.18-5.53, p = 0.016). No significant differences were found between the prevalence and storage temperature or hypermarket chain. The highest resistance rates in the isolates were reported to tetracycline (73.7%) followed by nitrofurantoin (53.3%), ampicillin (50%), amoxicillin-clavulanic acid, ceftriaxone (26.7%), and ciprofloxacin (23.3%). Eight isolates were potential extended-spectrum ß-lactamase-producers, all in imported frozen chicken (p < 0.0001). Additionally, 43.3% of the isolates were MDR and associated with frozen chicken (OR = 16.88, 95% CI: 2.55-111.47, p = 0.002). The findings indicate that while the prevalence of Salmonella in retail chicken in Qatar is moderate, a large proportion of them are MDR.

RESUMO

Data on the prevalence of MCR-producing Enterobacterales of animal origin are scarce from the Arabian Peninsula. We investigated the presence and variety of such strains from fecal specimens of poultry collected in four farms in the United Arab Emirates. Colonies from ten composite samples per farm grown on colistin-supplemented plates were PCR-screened for alleles of the mcr gene. Thirty-nine isolates selected based on species, colony morphology, and plasmid profile were subjected to whole genome sequencing. The panel of their resistance and virulence genes, MLST and cgMLST were established. Transferability and incompatibility types of the MCR-plasmids were determined. mcr-1.1 positive strains were identified in 36 of the 40 samples. Thirty-four multi-drug resistant Escherichia coli of 16 different sequence types, two Escherichia albertii, two Klebsiella pneumoniae and one Salmonella minnesota were identified. Beyond various aminoglycoside, tetracycline, and co-trimoxazole resistance genes, seven of them also carried ESBL genes and one blaCMY-2. Six IncHI2, 26 IncI2 and 4 IncX4 MCR-plasmids were mobilized, in case of the IncHI2 plasmids co-transferring ampicillin, chloramphenicol and tetracycline resistance. The diversity of mcr-1 positive strains suggest a complex local epidemiology calling for a coordinated surveillance including animals, retail meat and clinical cases.

RESUMO

INTRODUCTION: Building an antimicrobial resistance (AMR) surveillance system in a country requires analysis of available data on AMR in clinical isolates. This study's objective was to determine the AMR prevalence of Gram-negative bacterial (GNB) isolates cultured from clinical specimens at a major general hospital in Kuwait. METHODS: A retrospective descriptive study was conducted on AMR profiles of GNB clinical isolates (n=5290) between January and December 2018. Data were extracted from the laboratory information system in the hospital. The GNB organisms (i.e., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii) were isolated from five main locations at the hospital (i.e., intensive care units [ICUs], surgical wards, medical wards, pediatric wards, and outpatient polyclinics). RESULTS: Overall, high AMR prevalence (>50%) against ampicillin, cefuroxime, cefotaxime, ceftazidime, ciprofloxacin, and trimethoprim/sulfamethoxazole, were observed across the GNB organisms. However, low resistance prevalence (<10%) were observed against amikacin, ertapenem, meropenem, and piperacillin/tazobactam. In general, AMR prevalence in E. coli isolates from ICU, medical and surgical wards was significantly (p<0.05) higher compared to other locations, whereas, AMR prevalence in P. aeruginosa isolates from pediatric ward was higher (p<0.05) compared to other locations. The overall multidrug resistance (MDR) prevalence was 38.7% (95% CI: 37.4-40.0). The highest MDR prevalence was among E. coli isolates from respiratory specimens (48%); wounds, bones, or other tissues (47.7%); and body fluids (47.1%). Similarly, MDR prevalence in K. pneumoniae, P. aeruginosa, and A. baumannii isolated from respiratory specimens was significantly (p<0.05) higher compared to other specimen types. The most frequent MDR phenotypes in the four GNB organisms and across the different specimen types included three antimicrobial drug classes: penicillins, cephalosporins, and fluroquinolones. CONCLUSIONS: Our findings demonstrate high AMR prevalence among common Gram-negative bacteria at this major hospital. Monitoring data on antimicrobial susceptibility of common bacterial organisms is critical for assessing trends in AMR at hospitals and for informing policy decisions.

RESUMO

BACKGROUND: Estimating vaccine effectiveness (VE) against severe, acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among healthcare workers (HCWs) is necessary to demonstrate protection from the disease. Between 24 December 2020 and 15 June 2021, we determined the factors associated with vaccine coverage and estimated VE against SARS-CoV-2 infection in HCWs at a secondary hospital in Kuwait. METHODS: We extracted sociodemographic, occupational, SARS-CoV-2 infection, and vaccination data for eligible HCWs from the hospital records. Vaccine coverage percentages were cross-tabulated with the HCW factors. Cox regression was used to estimate hazard ratios in vaccinated versus unvaccinated. RESULTS: 3246 HCWs were included in the analysis, of which 82.1% received at least one vaccine dose (50.4% only one dose of ChAdOx1, 3.3% only one dose of BNT162b2, and 28.3% two doses of BNT162b2). However, 17.9% of HCWs were unvaccinated. A significantly lower vaccination coverage was reported amongst female HCWs, younger age group (20-30 years), and administrative/executive staff. The adjusted VE of fully vaccinated HCWs was 94.5% (95% CI = 89.4-97.2%), while it was 75.4% (95% CI = 67.2-81.6%) and 91.4% (95% CI = 65.1-97.9%) in partially vaccinated for ChAdOx1 and BNT162b2, respectively. CONCLUSIONS: BNT162b2 and ChAdOx1 vaccines prevented most symptomatic infections in HCWs across age groups, nationalities, and occupations.

RESUMO

BACKGROUND: Patients admitted to the Intensive Care Unit (ICU) are prone to develop nosocomial infections due to Multidrug-Resistant (MDR) organisms. Inappropriate and overuse of antibiotics play an important role in the emergence of MDR organisms, which cause life-threatening infections resulting in significant morbidity and mortality. METHODS: Retrospective surveillance-based study on healthcare-associated infections. The study conducted over two consecutive years 2018 and 2019, looking at ICU related infections of a regional secondary care general hospital and the data were recorded using the methods and definitions of the Kuwait National Healthcare-associated infections Surveillance System (KNHSS). RESULTS: A total of 1408 patients, admitted to ICU for 7922 days during the 2 years period. Eighty-nine patients were included in this study, where 48 developed one Hospital-acquired Infections (HAI) in the ICU while 25 and two patients presented with two and three HAIs, respectively. The HAIs included Bloodstream Infections (BSI) - 42.3%, pneumonia - 28.8%, Urinary Tract Infections (UTI) - 15.3%, skin and soft tissue infections - 9.6% and Clostridium difficile infection - 3.4%. The overall infection rate was 13.14 per 1000 patient-days. The rates for Device-associated (DA)-HAIs were 6.27 for Central Line-associated BSI (CLABSI) per 1000 Central Line (CL)-days, 4.21 for Ventilator-associated Pneumonia (VAP) per 1000 Mechanical Ventilator (MV)-days, and 1.91 Catheter-associated UTI (CAUTI) per 1000 Urinary Catheter (UC)-days. Data showed that device use ratios for CL, MV, and UC were 0.81, 0.74, and 0.98, respectively. Acinetobacter baumannii and Klebsiella pneumoniae were the most common organisms isolated from the ICU infections with highest rates of antibiotic resistance. CONCLUSION: Among DA-HAIs CLABSI was found to be most common in our ICU, followed by VAP and CAUTI. Gram-negative organisms with A. baumannii and K. pneumoniae being the leading causative agents with high antimicrobial resistance profiles.

RESUMO

Background: Coronavirus disease 2019 (COVID-19) pandemic is unprecedented. Health science students are the future frontliners to fight pandemics. Awareness and perception toward COVID-19 among health science students and staff at Kuwait University was assessed. Methods: Between June and July 2020, an online questionnaire was distributed to all students and staff at HCS. The questionnaire was divided into six sections: socio-demography, risk and awareness, preparedness and prevention, source of information, policies, and social stigma. Results: A total of 592 students and 162 staff completed the questionnaire. The prevalence of self-reported chronic condition among students and staff was 14.0% and 19.1%, respectively. Moreover, self-reported COVID-19 prevalence among students and staff was 2.7% and 1.2%, respectively. Interestingly, 54% of students and 38.3% of staff reported that they knew someone within their immediate social environment who have been/are infected with SARS-CoV-2. Among students, 92.4% wore face mask in indoor places (outside of their home) 'often/all the time' compared to wearing it outdoors (69.3%); whereas, for staff, it was more common to wear it outdoor than in indoor places (75.9% vs. 81.5%). Willingness to take COVID-19 vaccine was indicated by 50% of students 'strongly agreed' and an additional 25.8% agreed to taking it. Interest vaccine uptake was lower among staff (28.4% and 34.6% strongly agreed or agreed, respectively). Participants strongly agreed or agreed (72.5% and 19.6% of students as well as 68.5% and 22.2% of staff ) that wearing face mask in public should be obligatory. More than 18% of students and staff indicated that they would avoid contact with COVID-19 infected people. Conclusions: Responses of students and staff were mostly similar and showed that they follow precautionary measures to control spread of COVID-19, understand the viral transmission risk, and willing to raise awareness to reduce social stigma.

RESUMO

The study objective was to assess tobacco smoking prevalence in Kuwaiti adults in relation to sociodemographic characteristics. A cross-sectional study survey was conducted in 2014 on 3917 Kuwaiti citizens (18-69 years) following the World Health Organization (WHO) STEPwise Approach to Surveillance (STEPS) methodology. The study assessed prevalence of self-reported ever-smoking or currently smoking tobacco products and exposure to secondhand smoke in relation to demographic and smoking-related characteristics. The prevalence of "ever smoker" in men and women was 49.9% and 4.4%, respectively, whereas the prevalence of "current smoker" was 39.2% and 3.3%, respectively. Sex (adjusted OR [AOR], 19.2 [95% confidence interval (CI) 13.0-28.3], male versus female) was significantly associated with current smoking. Among daily smokers, 87.1% used manufactured cigarettes. The average daily number of manufactured cigarettes for men and women was 21.8 and 13.0, respectively. Mean age at smoking initiation was 17.5 years (95% CI 17.2-17.9). The prevalence of secondhand smoke at home and work was 38.6% and 29.9%, respectively. Half of Kuwaiti men have smoked at some point in their life with most of these being current smokers. Secondhand smoke is a common exposure at home and work, posing serious health risks to the population.

RESUMO

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a global pandemic. Seroprevalence surveillance is urgently needed to estimate and monitor the growing burden of coronavirus disease 2019 (COVID-19). The aim of this study is to estimate the seroprevalence of SARS-CoV-2 infection among worker population residing in areas under lockdown in Kuwait and investigated their risk factors associated with a positive status. From April 18 to May 10, 2020 a randomly sampled, worker-based survey was conducted in 7 governorate in Kuwait (Ahmadi, Farwaniya, Hawali, Asma, Jahra, and Mubarak Alkabeer) among 10,256 workers. SARS-CoV-2 IgG and IgM antibodies was assessed using a commercially point-of-care lateral flow immunoassay (Biozek medical COVID-19 IgG/IgM Rapid Test Cassette). We estimated an overall seroprevalence (IgG or IgM positive) of 5.9% (95% CI: 5.4-6.3). Notably, SARS-CoV-2 seropositivity was significantly higher in males (6.2%) than females (1.9%) ( p < 0.001). Furthermore, the seroprevalence was significantly different by age group, governorate, and nationality of the workers. These results highlighted that the relatively low prevalence of anti-SARS-CoV-2 antibodies in hotspot areas in a specific population. Thus, we emphasize to repeat the serosurvey in the general population to assess the magnitude of viral spread and monitor the growing burden of COVID-19 in Kuwait.

RESUMO

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a World Health Organization designated pandemic that can result in severe symptoms and death that disproportionately affects older patients or those with comorbidities. Kuwait reported its first imported cases of COVID-19 on February 24, 2020. Analysis of data from the first three months of community transmission of the COVID-19 outbreak in Kuwait can provide important guidance for decision-making when dealing with future SARS-CoV-2 epidemic wave management. The analysis of intervention scenarios can help to evaluate the possible impacts of various outbreak control measures going forward which aim to reduce the effective reproduction number during the initial outbreak wave. Herein we use a modified susceptible-exposed-asymptomatic-infectious-removed (SEAIR) transmission model to estimate the outbreak dynamics of SARS-CoV-2 transmission in Kuwait. We fit case data from the first 96 days in the model to estimate the effective reproduction number and used Google mobility data to refine community contact matrices. The SEAIR modelled scenarios allow for the analysis of various interventions to determine their effectiveness. The model can help inform future pandemic wave management, not only in Kuwait but for other countries as well.
