Cancer statistics in Yemen: incidence and mortality, in 2020.

BACKGROUND: The current cancer epidemiological profile in Yemen suffers from a lack of locally representative data and resources, posing a challenge in determining the real incidence, prevalence, survival and mortality rates, particularly data extracted from national hospitals. This study aims to provide a comprehensive overview of the cancer burden and trends in Yemen for 2020, including incidence and mortality rates. METHODS: The current study provides cancer statistics and their trends in Yemen, including incidence and mortality, in 2020 by using descriptive statistics. The data was obtained using the Global Cancer Observatory (GCO) 2020 online database. RESULTS: According to the (GCP) database in 2020, the crude incidence rate (CIR) of all cancers in Yemen was 55.2 per 100.000. The age-standardized rate (ASR) was 97.0 per 100.000, and the cumulative risk (0-74) was 22.0 per 100.000. The age-standardized rate (ASR) was 76.5 per 100.000, and the cumulative risk (0-74) was 19.6 per 100.000. Furthermore, the crude mortality rate (CIR) of all cancers was 40.6 per 100.000. Breast cancer was most prevalent in Yemen across all age groups and genders (31.1%), followed by colorectal cancer (7.7%) and leukemia (5.7%). Breast cancer also ranked as the primary cause of mortality at an estimated percentage of 13.5%, followed by colorectal cancer (8.8%) and stomach cancer (7.1%). CONCLUSION: Cancer has become a significant life-threatening illness in Yemen with an increase in the disease burden of breast cancer in women. Furthermore, leukemia in children and colorectal cancer in both sexes have experienced a more significant burden as well. Therefore, it is imperative for initiatives for cancer control and prevention to be prioritised at national and regional levels.

Diagnostic value of IgG antibody and stool antigen tests for chronic Helicobacter pylori infections in Ibb Governorate, Yemen.

The stool antigen test (SAT) and the serum Helicobacter pylori (H. pylori) IgG antibody assays exhibit significant utility in the clinical diagnosis of H. pylori infection and in distinguishing between acute and chronic infections. The main objective of the current study was to identify the diagnostic value of serum H. pylori IgG antibody and SAT in the detection of H. pylori infections among chronic H. pylori-infected patients residing in Ibb Governorate, Yemen. 200 patients with H. pylori infection, confirmed through positive results in the serum immunochromatographic antibody test, were selected for H. pylori infection confirmation using serum H. pylori IgG antibodies and SAT across diverse hospitals, gastroenterology, and Hepatology clinics in Ibb Governorate. After the selection of patients, blood and stool specimens were obtained from all participants and underwent analysis via the Statistical Package for the Social Sciences (SPSS). The prevalence of H. pylori infection demonstrated variability based on the confirmatory tests, with rates of 54% for SAT and 78.5% for serum H. pylori IgG antibody, contrasting with a 100% prevalence observed in the screening serum immunochromatographic antibody test. Clinically, the study categorized H. pylori infections into four stages, whereby a significant proportion of patients (40.5%) exhibited positivity for both serum H. pylori IgG antibody and SAT, indicative of active chronic infections. The majority of positive cases only manifested serum H. pylori IgG antibody presence (chronic infections) at 38%, whereas 13.5% exclusively tested positive for SAT, corresponding to acute infections. Moreover, 88% of patients did not have either serum H. pylori IgG antibody or SAT (absence of infections) during confirmatory tests. Noteworthy is the study's approach employing multiple tests for H. pylori infection detection, focusing predominantly on chronic infections-prevailing types caused by H. pylori. The results revealed a significant association between serum levels of H. pylori IgG antibody and SAT results with the presence of diverse gastrointestinal symptoms among patients, which increased with long H. pylori infection durations.

Circulating vaccine derived polio virus type 2 outbreak and response in Yemen, 2021-2022, a retrospective descriptive analysis.

BACKGROUND: The outbreaks of circulating Vaccine Derived Polio Viruses (cVDPVs) have emerged as a major challenge for the final stage of polio eradication. In Yemen, an explosive outbreak of cVDPV2 was reported from August 2021 to December 2022. This study aims to compare the patterns of cVDPV2 outbreak, response measures taken by health authorities, and impacts in southern and northern governorates. METHOD: A retrospective descriptive study of confirmed cases of VDPV2 was performed. The data related to cVDPV2 as well as stool specimens and environmental samples that were shipped to WHO-accredited labs were collected by staff of surveillance. Frequencies and percentages were used to characterize and compare the confirmed cases from the southern and northern governorates. The average delayed time as a difference in days between the date of sample collection and lab confirmation was calculated. RESULTS: The cVDPV2 was isolated from 227 AFP cases reported from 19/23 Yemeni governorates and from 83% (39/47) of environmental samples with an average of 7 months delayed from sample collection. However, the non-polio AFP (NPAFP) and adequate stool specimen rates in the north were 6.7 and 87% compared to 6.4 and 87% in the south, 86% (195) and 14%(32) out of the total 227 confirmed cases were detected from northern and southern governorates, respectively. The first and second cases of genetically linked isolates experienced paralysis onset on 30 August and 1st September 2021. They respectively were from Taiz and Marib governorates ruled by southern authorities that started vaccination campaigns as a response in February 2022. Thus, in contrast to 2021, the detected cases in 2022 from the total cases detected in the south were lower accounting for 22% (7 of 32) of compared to 79% (155 of 195) of the total cases the north. CONCLUSION: A new emerging cVDPV2 was confirmed in Yemen. The result of this study highlighted the impact of vaccination campaigns in containing the cVDPV2 outbreak. Maintaining a high level of immunization coverage and switching to nOPV2 instead of tOPV and mOPV2 in campaigns are recommended and environmental surveillance should be expanded in such a risky country.

Strengthening laboratories in response to outbreaks in humanitarian emergencies and conflict settings: Results, challenges and lessons from expanding PCR diagnostic capacities for COVID-19 testing in Yemen.

BACKGROUND: When the COVID-19 pandemic was declared, Yemen, a country facing years of conflict had only one laboratory with PCR testing capacity. In this article, we describe the outcome of the implementation of molecular based diagnostics platform in Yemen and highlight the key milestones the country went through to increase access to testing for its populations residing in a geographically vast and politically divided country. METHODS: A retrospective assessment of COVID-19 laboratory response activities was done detailing the needs assessment process, timelines, geographical coverage, and outcomes of the activities. Laboratory data was analyzed to construct the geographical locations of COVID-19 testing laboratories and the numbers of tests performed in each facility to highlight the demands of testing for travelers. Finally, we discuss the impact these activities had in enabling the movement of people across international borders for economic gains and in delivery of critical humanitarian aid. OUTCOME: PCR testing capacities in Yemen significantly improved, from one laboratory in Sanaa in April 2020 to 18 facilities across the country by June 2022. In addition, the number of functional Real-Time PCR thermocyclers increased from one to 32, the PCR tests output per day improved from 192 to 6144 tests per day. Results from analysis of laboratory data showed there were four peaks of COVID-19 in Yemen as October 2022. The majority of laboratory tests were performed for travelers than for medical or public health reasons. Demand for laboratory testing in Yemen was generally low and waned over time as the perceived risk of COVID-19 declined, in parallel with rollout of the COVID-19 vaccines. DISCUSSION/CONCLUSION: The successful expansion of laboratory testing capacity was instrumental in the control and management of COVID-19 cases and critical in the implementation of public response strategies, including restrictions on gathering. Laboratory testing also facilitated the movement of humanitarian agencies and delivery of aid and enabled hundreds of thousands of Yemeni nationals to travel internationally. By virtue of these outcomes, the impact of laboratory strengthening activities was thus felt in the health sector and beyond.

Factors associated with the cholera outbreak in Al-Mahweet-Yemen: Analytic Study.

INTRODUCTION: The emergence of cholera in 2016 in Yemen, worsened the morbidity and mortality of diarrheal diseases, particularly among children under five. Multiple outbreaks in Yemen are triggered by years of conflict and the collapse of basic infrastructure including water supply and sanitation systems. This study aims to assess factors associated with the cholera outbreak, in a cholera-prone region, in Al-Mahweet, Yemen. METHODOLOGY: We conducted a multivariate analysis of the data collected through a household survey of 384 households in Al-Mahweet, Yemen. RESULTS: Families with children under five years, large households, and those living in Al Mahweet district were associated with a higher incidence of cholera. Water treatment by boiling, filtering, and chlorination as a protective practice against cholera showed a borderline significance, while other WASH practices including regular hand washing, open defection, safe water source, and improved sanitation facilities were statistically insignificant. Community awareness of cholera transmission and prevention measures showed no association with cholera incidence. CONCLUSIONS: Findings suggest that living conditions, including large households and lack of access to treated water, increase the risk of cholera. Interventions to increase access to treated water and improve the hygienic conditions of large households are of central importance. Affected communities must receive effective educational campaigns that are adjusted to change hygienic practices and improve knowledge of cholera transmission and protection measures.

The prevalence of depression and anxiety among medical students in Yemen: A cross-sectional study.

BACKGROUND: Medical students may experience mental health disorders like anxiety and depression during medical school, which can negatively impact their productivity, education, and overall quality of life. Currently, there are no studies examining the mental health of medical students in Yemen. Our study aimed to estimate prevalence of depression and anxiety among Yemeni medical students. METHODS: The study utilized a cross-sectional design. A survey was conducted using validated psychometric tests: the Patient Health Questionnaire-9 (PHQ-9) for depression and the Generalized Anxiety Disorder-7 (GAD-7) for anxiety. A survey of medical students from 10 Yemeni medical schools took place from June 6 to July 20, 2023. It included only actively enrolled students in the 7-year undergraduate program. RESULTS: A total of 706 responses were collected. The prevalence of depression was 48.4 % for cases classified as moderate, moderately severe, and severe, while it was 20 % for cases categorized as moderately severe and severe. The rate of suicide ideation was 14.7 %. Anxiety was found to have a prevalence of 34.8 % for cases categorized as moderate and severe. Furthermore, both depression and anxiety were higher among females, and in earlier academic years; all of these associations had a p-value <0.05. Conversely, age, living status, income stability, and displacement risk all showed no significant association with depression or anxiety. CONCLUSION: Our study highlighted the prevalence of depression and anxiety among Yemeni medical students. Tailored interventions are imperative to address these challenges. Future research needs to examine the root causes that might contribute to these disorders.

High Prevalence of Musculoskeletal Disorders Among Dental Professionals: A Study on Ergonomics and Workload in Yemen.

BACKGROUND Dentists frequently have work-related musculoskeletal disorder (MSD) diseases, which are the profession's second most common cause of disability. Awareness of dental ergonomics is necessary for controlling MSDs associated with dental workload. Dental professionals need additional training in dental ergonomics to reduce serious complications associated with dental workload. This questionnaire-based study aimed to evaluate the understanding of physical ergonomics and musculoskeletal disorders in 310 dental health professionals and students in Yemen. MATERIAL AND METHODS This was a cross-sectional study was conducted among 400 dental professionals working in various clinics and universities in Sana'a City, Yemen. They received a self-administered questionnaire that was developed from earlier studies. Five sections made up the questionnaire. The first section of the survey included questions about sex, age, and clinical professions; the second section focused on ergonomic awareness; the third section asked about work conditions; the fourth section asked about the prevalence of musculoskeletal disorders; and the fifth section asked about interventions used. Data were analyzed using SPSS version 25.0, and a P value of ≤0.05 was considered significant. RESULTS Only 310 questionnaires were completed. The participants'; level of understanding of ergonomics was low. One-way ANOVA showed a significant portion of respondents reported having MSDs, and they frequently reported pain related to workload. The neck, lower back, upper back, and shoulders experienced the highest levels of pain. CONCLUSIONS The prevalence of MSDs was high among dental professionals, especially in the lower back, upper back, and shoulder. This necessitates preventive measures like ergonomic positions, ergonomic equipment, regular exercise, and work breaks.

Association between air raids and reported incidence of cholera in Yemen, 2016-19: an ecological modelling study.

BACKGROUND: Yemen continues to endure cholera outbreaks during ongoing conflict and destructive environmental events. Air raids have been used throughout the conflict to target military and civilian infrastructure. We aimed to assess the association between air raids and cholera incidence while taking into account geographical, environmental, economic, and demographic factors that drive outbreaks. METHODS: In this ecological modelling study, we used data from Sept 12, 2016, to Dec 29, 2019, for the number of air raids, vegetation coverage, surface water, precipitation, temperature, economic variables, and cholera case and population data to model the association between conflict and the weekly incidence of cholera (per 100 000 people) in Yemen. Data were transformed into weekly intervals and governorates were categorised according to air raid severity (the number of raids in the previous 3 months). We used a negative binomial generalised additive model that accounted for geographical location and environmental, temporal, economic, and demographic variables to estimate incidence rate ratios for the association between air raid severity and cases of cholera. FINDINGS: During the study period, 2 107 912 cases of cholera were reported in Yemen, and a minimum of 11 366 air raids were recorded. After controlling for relevant factors, compared with no air raids, all other levels of air raid severity were significantly associated with cholera incidence. The largest effect was noted in governorates with severe air raid levels (ie, ≥76 during the previous 3 months), which had an incidence rate ratio of 2·06 (95% CI 1·59-2·69; p<0·0001) for cholera compared with governorates with no air raids in the previous 3 months. Economic factors were also significantly associated with increased cholera incidence. INTERPRETATION: Air raids were significantly associated with the burden of cholera in Yemen, even after controlling for other relevant factors. Quantification of this relationship further shows that the cholera outbreak is largely a result of human action rather than a natural occurrence, and demonstrates the conflict's devastating effects on health. Our findings highlight the need for ceasefire and peacebuilding efforts, as well as infrastructure and economic restoration, to reduce Yemen's cholera burden. FUNDING: None.

Understanding risk factors for severe acute malnutrition among children during war conflict in yemen.

Severe acute malnutrition (SAM) is a major public health concern in Yemen, particularly in areas affected by ongoing conflict war. SAM is defined as a very low weight for height, by visible severe wasting, or by the presence of nutritional edema. The prevalence of SAM in Yemen has increased dramatically since the onset of the conflict. Prior studies have focused on evaluating prevalence, but this novel study aimed to assess the risk factors associated with SAM prevalence. Five thousand two hundred and seventeen patients of SAM admitted at 12 sentinel hospitals were enrolled, and data were collected and analyzed. Marasmus was the most common form. Numerous risk factors contribute to the high prevalence of SAM in Yemen, including food insecurity. The current conflict has hampered food production, distribution, and access. Awareness of risk factors can prevent SAM in the general population.

Polio outbreak response, Yemen.

Problem: A decrease in vaccine coverage in conflict-affected areas has placed Yemen at higher risk of polio outbreaks caused by vaccine-derived poliovirus strains. Approach: In response to polio outbreaks, the Yemeni health ministry and partners initiated multiple vaccination campaigns to deliver vaccines to children. We also implemented several measures to enhance communication, education, health promotion and hygiene, especially in camps for internally displaced people. Local setting: In 2009, Yemen achieved polio-free status and maintained it until 2019. However, the ongoing political conflict since 2015, coupled with challenges in delivering the polio vaccine to conflict-affected areas, resulted in two polio outbreaks: 35 cases caused by vaccine-derived poliovirus strain 1 between 2019 and 2021, and 230 cases due to vaccine-derived poliovirus strain 2 between November 2021 and December 2022. Relevant changes: In response to the first outbreak, by the end of 2020, we vaccinated 7.2 million children through nationwide vaccination campaigns, except in Sa'ada governorate due to a ban by the authorities. By the end of 2021, 3 800 313 children younger than 5 years had received polio vaccines. For the second outbreak, by the end of 2022, 4 463 389 vaccines had been given to children younger than 10 years, and 1 217 423 to those younger than 5 years. Lessons learnt: Vaccination campaigns in conflict-affected areas with low vaccine coverage remain crucial in eradicating polio. Efforts are needed to reach vulnerable groups such as displaced populations. Advocacy, communication and social mobilization actions help ensure broader public inclusion and participation in vaccination efforts to prevent polio outbreaks.

Genomic epidemiology reveals multidrug resistant plasmid spread between Vibrio cholerae lineages in Yemen.

Since 2016, Yemen has been experiencing the largest cholera outbreak in modern history. Multidrug resistance (MDR) emerged among Vibrio cholerae isolates from cholera patients in 2018. Here, to characterize circulating genotypes, we analysed 260 isolates sampled in Yemen between 2018 and 2019. Eighty-four percent of V. cholerae isolates were serogroup O1 belonging to the seventh pandemic El Tor (7PET) lineage, sub-lineage T13, whereas 16% were non-toxigenic, from divergent non-7PET lineages. Treatment of severe cholera with macrolides between 2016 and 2019 coincided with the emergence and dominance of T13 subclones carrying an incompatibility type C (IncC) plasmid harbouring an MDR pseudo-compound transposon. MDR plasmid detection also in endemic non-7PET V. cholerae lineages suggested genetic exchange with 7PET epidemic strains. Stable co-occurrence of the IncC plasmid with the SXT family of integrative and conjugative element in the 7PET background has major implications for cholera control, highlighting the importance of genomic epidemiological surveillance to limit MDR spread.

Concurrent wasting and stunting among marginalised children in Sana'a city, Yemen: a cross-sectional study.

Concurrent wasting and stunting (WaSt) is a serious form of malnutrition among young children, particularly vulnerable groups affected by the conflict. Understanding the prevalence and risk factors of WaSt among vulnerable children is important to develop effective intervention measures to reduce the burden of WaSt. The present study aimed to identify the prevalence of and risk factors for WaSt among marginalised children aged 6-59 months in Sana'a city, Yemen. A community-based cross-sectional design was conducted on a total sample size of 450 marginalised children aged 6-59 months who lived at home with their mothers. Multivariable logistic regression analysis was performed and the prevalence of WaSt was found to be 10⋅7 %. Children aged 24-59 months were protected from WaSt (adjusted odds ratio (AOR) 0⋅40, 95 % confidence interval (CI) 0⋅21, 0⋅75). A higher prevalence of WaSt was associated with male sex (AOR 2⋅31, 95 % CI 1⋅13, 4⋅71), no history of being breastfed (AOR 3⋅57, 95 % CI 1⋅23, 10⋅39), acute diarrhoea (AOR 2⋅12, 95 % CI 1⋅12, 4⋅02) and family income sources of assistance from others (AOR 2⋅74, 95 % CI 1⋅08, 6⋅93) or salary work (AOR 2⋅22, 95 % CI 1⋅10, 4⋅47). Continued breast- and bottle-feeding were not associated with WaSt in children aged 6-23 months. Mothers' age, education and work status, family size and drinking water source were not associated with WaSt. Overall, we found that the prevalence of WaSt among marginalised children remained high. Interventions to improve household income, hygienic conditions and child feeding practices are necessary to promote child growth.

Responding to COVID-19 pandemic at the local level: lessons from Yemen.

Background: The health authorities in Hadhramaut Valley and Desert responded to the COVID-19 pandemic differently from other areas in Yemen. Aims: To document the response of the local authority and Ministry of Health in Hadhramaut to COVID-19. Methods: The local authority in Syoun (Hadhramaut Valley) convened a meeting of all key players from the health and related sectors in February 2020 where a decision was made to establish a committee to evaluate the health situation and assess the needs. Based on the results of these assessments, a plan was designed to respond to the pandemic. We reviewed available documents on the COVID-19 response in Hadhramaut, interviewed the main stakeholders, and conducted site visits to the COVID-19 response centres. Results: There was evidence of the crucial role played by the local authority in response to COVID-19. They established 3 well-equipped isolation centres with a total of 142 beds, a stock of 2250 oxygen cylinders, 2 new polymerase chain reaction units, a simplified referral system, and an effective patient follow-up and oxygen home therapy strategy. Conclusion: Political commitment at the local level is crucial to bridge the gap between policy and implementation, especially during infectious disease outbreaks. It is important to train public health leaders on how to effectively assess local health needs and develop effective and efficient response strategy. Lessons from this study in Hadhramaut provide evidence on how local authorities can coordinate response to emerging health needs and update their strategies.

A disfiguring neglected tropical disease sweeps war-torn Yemen: a community-based study of prevalence and risk factors of cutaneous leishmaniasis among rural communities in the western highlands.

BACKGROUND: Cutaneous leishmaniasis (CL) is a major health problem in Yemen and is endemic in many rural areas across the country. METHODS: A community-based cross-sectional survey followed by unmatched case-control comparisons was conducted among 612 participants in Utmah district, western Yemen. A total of 223 participants were included in the case-control analysis to identify the significant risk factors. Skin scrapping samples were examined by microscopy and internal transcribed spacer 1 nested polymerase chain reaction. RESULTS: Overall, 33% (202/612) of the participants had active skin lesions and/or scars that met the clinical criteria for CL. A total of 90 (14.7%) participants had suspected active CL lesions; however, a prevalence of 8.7% (53/612) was obtained based on molecular and parasitological examination, with Leishmania tropica being the only causative agent identified. Multivariable logistic regression analyses showed that being ≤10 y old, being female, living in houses with cracked walls, living in the presence of other family members with typical ulcerating skin diseases and sleeping outside were factors significantly associated with an increased likelihood of having CL. Moreover, keeping livestock on the ground floor of the house was significantly associated with a decreased likelihood of having CL. CONCLUSION: The study reveals an alarmingly high prevalence of CL among the studied population. Therefore there is an urgent need for effective control measures and improved treatment efforts against this devastating disease.

Prevalence and drivers of female genital mutilation/cutting in three coastal governorates in Yemen.

BACKGROUND: Female genital mutilation/cutting (FGM/C), a violation of human rights, remains common in the coastal areas of Yemen. OBJECTIVE: This study aimed to identify the prevalence of FGM/C and its risk factors among the youngest daughters in families in the Yemeni coastal areas, as well as the knowledge and attitudes of the local population towards FGM/C. METHODS: A cross-sectional survey was conducted among 646 women and 345 men from six districts in three Yemeni coastal governorates between July and September 2020 using a structured questionnaire. Categorical data were described by proportion. The chi-square test was used to identify factors associated with FGM/C. All factors with a p-value of ≤ 0.05 were included in the multivariate analysis. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) were calculated in the multivariate logistic regression analysis. RESULTS: The prevalence of FGM/C in Yemeni coastal areas was 89.0% (95% CI 84.0%-92.5%) among women and 79.8% (95% CI 73.5%-84.8%) among the youngest daughters in the surveyed families. Nearly two-thirds of women and half of the men recorded a poor knowledge level about the harms of FGM/C. Furthermore, almost two-thirds of both women and men would like to continue the practice of FGM/C. Among women, significant predictors of FGM/C among youngest daughters included advanced maternal age of ≥ 40 years (AOR 7.16, 95% CI 2.73-18.76), mother's desire to continue FGM/C (AOR 8.07, 95% CI 3.64-17.89), and living in a rural area (AOR 3.95, 95% CI 1.51-10.30). Daughters of mothers who did not undergo FGM/C were more protected from FGM/C than those whose mothers had undergone FGM/C (AOR 0.04, 95% CI 0.02-0.09). Among men, the father's desire to continue FGM/C (AOR 15.10, 95% CI 6.06-37.58) was significantly associated with FGM/C among the youngest daughters. CONCLUSION: This study confirmed that FGM/C is still prevalent among communities in Yemeni coastal areas. Thus, community-based interventions with a focus on the rural population are vital to improving the awareness of various harms of FGM/C.

Public health impact of the spread of Anopheles stephensi in the WHO Eastern Mediterranean Region countries in Horn of Africa and Yemen: need for integrated vector surveillance and control.

BACKGROUND: Anopheles stephensi is an efficient vector of both Plasmodium falciparum and Plasmodium vivax in South Asia and the Middle East. The spread of An. stephensi to countries within the Horn of Africa threatens progress in malaria control in this region as well as the rest of sub-Saharan Africa. METHODS: The available malaria data and the timeline for the detection of An. stephensi was reviewed to analyse the role of An. stephensi in malaria transmission in Horn of Africa of the Eastern Mediterranean Region (EMR) in Djibouti, Somalia, Sudan and Yemen. RESULTS: Malaria incidence in Horn of Africa of EMR and Yemen, increased from 41.6 in 2015 to 61.5 cases per 1000 in 2020. The four countries from this region, Djibouti, Somalia, Sudan and Yemen had reported the detection of An. stephensi as of 2021. In Djibouti City, following its detection in 2012, the estimated incidence increased from 2.5 cases per 1000 in 2013 to 97.6 cases per 1000 in 2020. However, its contribution to malaria transmission in other major cities and in other countries, is unclear because of other factors, quality of the urban malaria data, human mobility, uncertainty about the actual arrival time of An. stephensi and poor entomological surveillance. CONCLUSIONS: While An. stephensi may explain a resurgence of malaria in Djibouti, further investigations are needed to understand its interpretation trends in urban malaria across the greater region. More investment for multisectoral approach and integrated surveillance and control should target all vectors particularly malaria and dengue vectors to guide interventions in urban areas.

Prevalence and factors associated with the utilisation of modern contraceptive methods among married women of childbearing age in Yemen: a secondary analysis of national survey data.

OBJECTIVE: Improving reproductive health requires access to effective contraception and reducing the unmet need for family planning in high-fertility countries, such as Yemen. This study investigated the utilisation of modern contraception and its associated factors among married Yemeni women aged 15-49 years. DESIGN AND SETTING: A cross-sectional study was conducted. Data from the most recent Yemen National Demographic and Health Survey were used in this study. PARTICIPANTS: A sample of 12 363 married, non-pregnant women aged 15-49 was studied. The use of a modern contraceptive method was the dependent variable. DATA ANALYSIS: A multilevel regression model was used to investigate the factors associated with the use of modern contraception in the study setting. RESULTS: Of the 12 363 married women of childbearing age, 38.0% (95% CI: 36.4 to 39.5) reported using any form of contraception. However, only 32.8% (95% CI: 31.4 to 34.2) of them used a modern contraceptive method. According to the multilevel analysis, maternal age, maternal educational level, partner's educational level, number of living children, women's fertility preferences, wealth group, governorate and type of place of residence were statistically significant predictors of modern contraception use. Women who were uneducated, had fewer than five living children, desired more children, lived in the poorest households and lived in rural areas were significantly less likely to use modern contraception. CONCLUSIONS: Modern contraception use is low among married women in Yemen. Some individual-level, household-level and community-level predictors of modern contraception use were identified. Implementing targeted interventions, such as health education on sexual and reproductive health, specifically focusing on older, uneducated, rural women, as well as women from the lowest socioeconomic strata, in conjunction with expanding availability and access to modern contraceptive methods, may yield positive outcomes in terms of promoting the utilisation of modern contraception.

Prevalence, aetiology, vaccination coverage and spatio-temporal pattern among patients admitted with acute bacterial meningitis to the sentinel hospital surveillance network in Yemen, 2014-20, before and during the civil war.

BACKGROUND: Acute bacterial meningitis (ABM) is a serious health issue in Yemen where civil war, which continues unabated, has crippled the healthcare system. We conducted a nationwide retrospective observational study in Yemeni sentinel hospitals to identify the prevalence, aetiology, vaccination coverage and spatio-temporal pattern of ABM in children aged <5 years before and during the civil war, 2014-20. METHODS: Cerebrospinal fluid samples were collected from hospitalized children and were analysed macroscopically for appearance and microscopically by Gram stain and white blood cell count. Culture and latex agglutination tests were performed. Data on the prevalence of and vaccination coverage for ABM were obtained from the Ministry of Health. Joinpoint regression was used to assess the annual percent change (APC) of ABM prevalence and vaccination coverage. Pearson's correlation was used to evaluate the association between ABM prevalence and vaccination coverage. RESULTS: In total, 11 339 hospitalized children had suspected cases of ABM (prevalence, 40.07/100 000 of the whole Yemeni population) and 2.6% (293/11 339) of suspected ABM cases were confirmed (prevalence, 1.04/100 000 of the whole Yemeni population). The dominant pathogens were Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae type b (Hib). The civil war reduced the Hib and pneumococcal vaccination coverage (APC = -1.92), reaching its lowest (79.5%) in 2018. The prevalence of suspected ABM increased (APC = 3.46), reaching its maximum (6.08/100 000 of the whole Yemeni population) in 2019. The conflict inversely correlated with the ABM prevalence and vaccination coverage (Pearson correlation coefficient (r), -0.69 to -0.53). Ta'izz region, which was severely affected by the civil war, had the highest prevalence of suspected ABM (120.90/100 000 of the whole Yemeni population) and lowest vaccination coverage (60%). CONCLUSIONS: The civil war had a negative impact on vaccination coverage and coincided with increasing prevalence of ABM in Yemen. Streptococcus pneumoniae is the dominant causative pathogen.

An assessment of the current epidemiological and laboratory capacities for influenza-like illnesses and severe acute respiratory infection surveillance, Yemen 2022.

Background and Objectives: We aim to re-activate influenza sentinel surveillance system in Yemen after disruption related to repurposing for COVID-19 pandemic. WHO Country Office (CO) in collaboration with Yemen's Ministry of Public Health and Population (MOPH&P) jointly conducted an assessment mission to assess the current situation of the influenza sentinel surveillance system and assess its capacity to detect influenza epidemics and monitor trends in circulating influenza and other respiratory viruses of epidemic and pandemic potential. This study presents the results of the assessment for three sentinel sites located in Aden, Taiz, and Hadramout/Mukalla. Methodology: A mixed methods approach was used to guide the assessment process and to help achieve the objectives. Data were collected as follows: desk review of the sentinel sites records and data; interviews with stakeholders, including key informants and partners; and direct observation through field visits to the sentinel sites, MOPH&P and the Central Public Health Laboratory (CPHL). Two assessment checklists were used: assessment of sentinel sites for SARI surveillance, and checklist for assessment of availability of SARI sentinel surveillance. Results and Conclusion: COVID-19 has affected health systems and services, and this was demonstrated in this assessment. The influenza sentinel surveillance system in Yemen is not effectively functional; however, there is plenty of room for improvement if investment in the system's restructuring, training, building technical and laboratory capacities, and conducting continuous and regular supervision visits.

Psychological effect of COVID-19 pandemic on healthcare professionals of Yemen and coping strategies.

COVID-19 pandemic has triggered psychological stress such as anxiety and depression among people around the globe. Due to the nature of the job, healthcare professionals (HCPs) are at high risk of infection and are facing social stigma as well. This research was conducted with the objective to evaluate the psychological influence of the COVID-19 pandemic among HCPs in Yemen and the coping strategies adopted thereof. A web-based, as well as face-to-face cross-sectional study was carried out from July to December 2021 among HCPs of Yemen. The generalized anxiety disorder (GAD-7), patient health questionnaire (PHQ-9), and Brief-COPE scales were applied for the evaluation of anxiety, depression, and coping strategies. A total of 197 HCPs participated in the study where 28.4% and 43.1% had anxiety and depression respectively. The prevalence of both anxiety and depression in the majority were found of the minimal to none and mild categories (71.6% vs. 56.9% respectively). The respondents who had received training on COVID-19 had statistically significant lower GAD-7 scores than those who did not (6.32 vs. 8.02 respectively). A significant statistical difference was observed between physicians versus nurses regarding depression based on the working area (p < 0.05). The physician and pharmacist had a significant positive association with brief COPE scores at the 50th centile compared to other HCPs. The female respondents had statistically significant higher mean Brief COPE scores than male respondents (78.11 vs. 69.50 respectively). Our findings illustrate the requirement for efficient policies through administrative, clinical, and welfare perspectives from the regulatory body in preparedness and preventive measures towards such a pandemic that aids HCPs to provide service in a stress-free condition and assurance of a better healthcare system..
