Background: Women in the fisher communities in coastal regions of Bangladesh are engaged in a wide range of fishery activities. However, there is limited evidence available on the occupational hazards and risks experienced by them. Method: The study was conducted among fishing colonies in Cox's Bazar and Chattogram districts in Bangladesh. This was a cross-sectional study blending qualitative and quantitative approaches. The qualitative component comprised five focus group discussions to understand the occupational context, hazards, and risks faced by the fisherwomen, informing the questionnaire design for the subsequent survey. The quantitative survey involved a sample of 207 women from fisher communities, gathering socio-demographic information, occupational hazards, risks, and health and safety practices. Findings: The study found a high occurrence of occupational hazards, health risks and limited availability of preventive measures among the women in fisher communities. Occupational hazards include physical safety hazards such as slippery surfaces and fish cutting instruments, and physical hazards like prolonged sun exposure and noise. Chemical hazards like pesticides and saltwater, ergonomic hazards such as prolonged uncomfortable posture and heavy lifting, and biological hazards including inadequate sanitation facilities were prevalent. The study also identified the potential occupational risks, and the outcomes resulting from the hazards, including injuries (87.44%), musculoskeletal conditions (69.08%), skin diseases/conditions (56.52%), eye complaints (33.82%), severe respiratory distress (24.15%) and high incidence of self-reported communicable diseases. Most women (78.26%) did not use personal protective equipment, and the majority (93.72%) lacked a workplace first aid kit. Conclusion: The study revealed a high prevalence of occupational hazards and health risks, including injuries and diseases, among Bangladeshi women in fisher communities with insufficient safety measures. Collaboration among government, NGOs, development partners, fisheries stakeholders, and the community is imperative for targeted training, innovative procedures, ergonomic solutions, provision of protective equipment, and advocacy to enhance the well-being of these women.

Background: Although many studies were conducted on COVID-19 knowledge, attitude, and practice (KAP) among the general population in many countries, very little is known about refugees, particularly Rohingya refugees in Cox's Bazar. A vast array of risk communication and community engagement (RCCE) interventions were implemented in Cox's Bazar with the intent of reducing disease transmission by empowering the community to adopt public health measures. Objectives: The study aimed to assess the level of knowledge, attitude and practice (KAP) of COVID-19 preventive measures among the Rohingya refugees in Cox's Bazar, and to identify their socio-demographic determinants. Materials and methods: A cross-sectional study was conducted with 500 Rohingya individuals. Participants in the study were Rohingya refugees residing in five randomly selected camps where International Organization for Migration (IOM) Health was operating. Using a structured questionnaire, skilled community health workers surveyed the Rohingya population. In addition to the survey on knowledge, attitude, and practice, the study gathered information on the perspectives and relevance of sociodemographic factors that influence KAP. Results: The study findings indicate that the mean scores for knowledge, attitude, and practice were 9.93, 7.55, and 2.71 respectively. Association was found between knowledge and practice level and age group–the elderly age group (>/ = 61 years) had less level of knowledge (AOR 0.42, P value = 0.058) and the late mid-age group (46–60 years) had better practice level (AOR 2.67, P value <0.001). Conclusions: Our study found that the Rohingya refugee community in Cox's Bazar has improved knowledge and attitude toward COVID-19 preventive measures. However, the practice level of these measures remains low compared to the knowledge and positive attitude. The reason behind the poor practice of preventive measures needs to be identified and addressed engaging the community in similar future outbreaks. [ABSTRACT FROM AUTHOR]

Background Unrest in Myanmar in August 2017 resulted in the movement of over 700,000 Rohingya refugees to overcrowded camps in Cox's Bazar, Bangladesh. A large outbreak of diphtheria subsequently began in this population. Methods and findings Data were collected during mass vaccination campaigns (MVCs), contact tracing activities, and from 9 Diphtheria Treatment Centers (DTCs) operated by national and international organizations. These data were used to describe the epidemiological and clinical features and the control measures to prevent transmission, during the first 2 years of the outbreak. Between November 10, 2017 and November 9, 2019, 7,064 cases were reported: 285 (4.0%) laboratory-confirmed, 3,610 (51.1%) probable, and 3,169 (44.9%) suspected cases. The crude attack rate was 51.5 cases per 10,000 person-years, and epidemic doubling time was 4.4 days (95% confidence interval [CI] 4.2-4.7) during the exponential growth phase. The median age was 10 years (range 0-85), and 3,126 (44.3%) were male. The typical symptoms were sore throat (93.5%), fever (86.0%), pseudomembrane (34.7%), and gross cervical lymphadenopathy (GCL; 30.6%). Diphtheria antitoxin (DAT) was administered to 1,062 (89.0%) out of 1,193 eligible patients, with adverse reactions following among 229 (21.6%). There were 45 deaths (case fatality ratio [CFR] 0.6%). Household contacts for 5,702 (80.7%) of 7,064 cases were successfully traced. A total of 41,452 contacts were identified, of whom 40,364 (97.4%) consented to begin chemoprophylaxis; adherence was 55.0% (N = 22,218) at 3-day follow-up. Unvaccinated household contacts were vaccinated with 3 doses (with 4-week interval), while a booster dose was administered if the primary vaccination schedule had been completed. The proportion of contacts vaccinated was 64.7% overall. Three MVC rounds were conducted, with administrative coverage varying between 88.5% and 110.4%. Pentavalent vaccine was administered to those aged 6 weeks to 6 years, while tetanus and diphtheria (Td) vaccine was administered to those aged 7 years and older. Lack of adequate diagnostic capacity to confirm cases was the main limitation, with a majority of cases unconfirmed and the proportion of true diphtheria cases unknown. Conclusions To our knowledge, this is the largest reported diphtheria outbreak in refugee settings. We observed that high population density, poor living conditions, and fast growth rate were associated with explosive expansion of the outbreak during the initial exponential growth phase. Three rounds of mass vaccinations targeting those aged 6 weeks to 14 years were associated with only modestly reduced transmission, and additional public health measures were necessary to end the outbreak. This outbreak has a long-lasting tail, with Rt oscillating at around 1 for an extended period. An adequate global DAT stockpile needs to be maintained. All populations must have access to health services and routine vaccination, and this access must be maintained during humanitarian crises., Author(s): Jonathan A. Polonsky 1,2,*, Melissa Ivey 3, Md.

The leading infectious cause of death in children worldwide is lower acute respiratory infection (LARI), particularly pneumonia. We enrolled a total of 538 acute respiratory infection (ARI) cases according to WHO criteria and age-sex matched 514 controls in the Forcibly Displaced Myanmar National (FDMN) refugee camps in Cox's Bazar, Bangladesh, between June 2018 and March 2020 to investigate the role of bacteria, viruses, and their co-infection patterns and observe Streptococcus pneumoniae (S. pneumoniae) serotype distribution. According to the etiological findings, children ≤5 years of age have a higher bacterial positivity (90%) and viral positivity (34%) in nasopharyngeal samples (NPS) compared to those >5 years of age, in both ARI cases as well as for the control group. Among the bacteria, S. pneumoniae was predominant in both cases and controls (85% and 88%). Adenovirus (ADV)(34), influenza virus A and B (IFV-A, B)(32,23), and respiratory syncytial virus (RSV)(26) were detected as the highest number among the viruses tested for the ARI cases. The total number of viruses was also found higher in ≤5 years of age group. Within this group, positive correlation was observed between bacteria and viruses but negative correlation was observed between bacteria. Both single and co-infection for viruses were found higher in the case group than the control group. However, co-infection was significantly high for Streptococcus aureus (S. aureus) and Haemophilus influenzae b (H. influenza b) (p<0.05). Additionally, semi-quantitative bacterial and viral load was found higher for the ARI cases over control considering Cycle threshold (Ct)≤30. Pathogen identification from blood specimens was higher by qRT-PCR than blood culture (16% vs 5%, p<0.05). In the S. pneumoniae serotype distribution, the predominant serotypes in ARI cases were 23F, 19A, 16F, 35B, 15A, 20 and 10F, while 11A, 10A, 34, 35A and 13 serotypes were predominant in the control group. Pathogen correlation analysis showed RSV positively correlated with human metapneumovirus (HMPV), S. aureus and H. influenza b while S. pneumoniae was negatively correlated with other pathogens in ≤5 years age group of ARI cases. However, in >5 years age group, S. aureus and H. influenza b were positively correlated with IFVs, and S. pneumoniae was positively correlated with HMPV and ADV. Logistic regression data for viruses suggested among the respondents in cases were about 4 times more likely to be RSV positive than the control. Serotype distribution showed 30% for PCV10 serotypes, 41% for PCV13 and 59% for other serotypes. Also, among the 40 serotypes of S. pneumoniae tested, the serotypes 22F, Sg24, 9V, 38, 8, and 1 showed strong positive correlation with viruses in the case group whereas in the control group, it was predominant for serotypes 14, 38, 17F and 39 ARI cases were prevalent mostly in monsoon, post-monsoon, and winter periods, and peaked in September and October. Overall these region-specific etiological data and findings, particularly for crisis settings representing the FDMNs in Cox's Bazar, Bangladesh, is crucial for disease management and disease prevention control as well as immunization strategies more generally in humanitarian crisis settings. Author summary: Acute respiratory infections (ARIs) are one of the most common communicable diseases in crisis settings, causing significant morbidity and mortality. Non-comparable as well as little aetiological data from refugee camps and surveillance, make it difficult to compare the prevalence of ARI disease between crisis and non-crisis contexts. In the world's largest refugee settlement situated in Cox's Bazar, Bangladesh, very little is known about the etiology of ARIs. To our best knowledge, this is the first case-control prospective study to evaluate the level of involvement of each etiological agent in the onset of LARI etiology, and the association between respiratory viral infections and invasive pneumococcal infections, S. pneumoniae serotype distribution, antimicrobial resistance pattern both in case and control group. Our study showed that ≤5 years age group was the most vulnerable, having the highest number of bacteria as well as viruses both in the case and control group. S. pneumoniae was the predominant bacteria, whereas, among the viruses ADV, IFVs, and RSV were predominant. Semi-quantitative bacterial as well as viral load was found higher in the case group. Positive correlation between viruses and other pathogens was higher in cases of RSV than in the control group. However, single as well as co-infection between viruses were significantly high among the ARI case while for bacteria it was comparable between the case and control group. ARI case enrollment peaked in September and October in the FDMN camps in Bangladesh. [ABSTRACT FROM AUTHOR]

Background: Rohingya refugees in Bangladesh are vulnerable to infectious diseases such as COVID-19 due to the crowded living conditions with fragile shelters, and limited water, sanitation and hygiene facilities and practices. While risk communication and community engagement (RCCE) is the cornerstone of outbreak control, there is limited evidence available on the effectiveness of the RCCE strategies in this setting., Objectives: The goal of this study is to evaluate the effectiveness of RCCE strategies and to explore the challenges and community recommendations in relation to COVID-19 preventive measures in the context of Rohingya refugee camps in Bangladesh., Materials and Methods: It was a qualitative study. Methods used were (a) observation of RCCE intervention by 3 clinical supervisors accompanying 25 Community Health Workers (CHWs) and (b) 5 focus group discussions engaging 60 community representatives. Data were analyzed using a thematic analysis approach, separately for observation and focus group discussions., Results: The study identified a number of good practices of RCCE, including selecting CHWs from the local community, engaging female CHWs, using local dialect, and collaborating with community/religious leaders. Certain good practices need scaling up, such as utilization of multiple communication methods and interpersonal communication skills. Some areas need improvement, such as CHWs being overburdened with multiple tasks, less effort to active listening, repeated delivery of same messages, inadequate linkage to culture, context, and resources, and less effort to empower the community. Engaging the community, five critical themes were identified in relation to poor COVID-19 preventive practices: culture, religion, and language; local context and resources; community trust and interaction with aid workers; communication methods; and gender and social inclusion. Religious misinterpretation, cultural barriers, physical barriers, lack of resources, breach of trust between the community and aid workers, inconsistent/complex messages, lack of gender and social inclusion, and stigmatization are among some key factors. Some key actions were recommended to improve COVID-19 RCCE strategy., Conclusion: We urge the RCCE partners to make use of the findings and recommendations to develop a robust RCCE strategy relevant to local culture and context, responsive to people's concerns and needs, and inclusive of gender, age and social vulnerabilities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Halder, Hasan, Mohamud, Nyawara, Okello, Mizan, Sayum and Hossain.)
