Background Norovirus is a major cause of endemic acute gastroenteritis (AGE) worldwide. We described the epidemiology, risk factors, and genotypic distribution of noroviruses among hospitalized patients of all ages in Bangladesh. Methods From March 2018 to October 2021, 1250 AGE case patients and controls (age, sex, season, and site matched) were enrolled at 10 hospitals. Demographic and clinical information was collected; real-time reverse-transcriptase polymerase chain reaction (RT-PCR) used to test stool specimens, and positive samples were genotyped. Results Norovirus was detected in 9% of cases (111 of 1250) and 15% (182 of 1250) of controls. Eighty-two percent of norovirus-positive cases were in children <5 years old. Norovirus-positive AGE hospitalizations occurred year-round, with peaks in April and October. Risk factors for norovirus included age <5 years (adjusted odds ratio, 3.1 [95% confidence interval, 1.9–5.2]) and exposure to a patient with AGE in the 10 days before enrollment (3.8 [1.9–7.2]). GII.3[P16] and GII.4 Sydney[P16] were the predominant genotypes. Conclusions We highlight the burden of norovirus in hospital settings. Young age and recent exposure to a patient with AGE were risk factors for norovirus. A high prevalence of norovirus among controls might represent asymptomatic reinfections or prolonged shedding from a previous infection; carefully designed longitudinal studies are needed to improve our understanding of norovirus infections in Bangladesh.

Introduction: Increasing antibiotic usage is a leading health threat that develops antibiotic resistance. The current practice of antibiotic use among under-five children are unavailable in Bangladesh. We aim to identify the factors of antibiotic use among under-five children with infectious diseases. Methodology: A cross-sectional multiple indicators cluster survey (MICS) was conducted in 2019 across Bangladesh. This survey of 23,099 children under the age of five was randomly selected by using a two-stage stratified sampling method. The first stage involved randomly selecting 32,200 enumeration clusters. In second stage, households where 15-45-years-old women lived were randomly selected from within each cluster. The Poisson regression models were performed to estimate the prevalence ratio (PR). Results: We found 36.7% (8447/23,099) under-five children with infectious diseases. The proportion of antibiotic use was reported as 32.6%. Antibiotic use was associated with wealth (poorest vs. rich adjusted prevalence ratio (APR) = 1.07; 95% CI: 0.94-1.22) and mother's education (pre-primary vs. higher: APR = 1.14; 95% CI: 1.03-1.27). Oral and injectable antibiotics were used in cases of fever (30.5%), diarrhea (4.5%), fever with cough (47.6%). Cotrimoxazole (31.0%) and amoxicillin (29.0%) were consumed for fever with cough while cotrimoxazole (14.0%) and amoxicillin (11.0%) were consumed for fever with diarrhea. They received antibiotics from drug stores (71.9%) without prescription and private healthcare (52.1%). Conclusions: Overall, one-third of the under-five children in Bangladesh consumed antibiotics to treat infectious diseases. Multiple factors contribute to the prevalence of antibiotic use. The results highlight the need to regulate antibiotic use and prioritize national intervention programs. [ABSTRACT FROM AUTHOR]

For supporting antibiotic stewardship interventions, the World Health Organization (WHO) classified antibiotics through the AWaRe (Access, Watch, and Reserve) classification. Inappropriate use of antimicrobials among hospital-admitted patients exposes them to the vulnerability of developing resistant organisms which are difficult to treat. We aimed to describe the proportion of antibiotic use based on the WHO AWaRe classification in tertiary and secondary level hospitals in Bangladesh. A point prevalence survey (PPS) was conducted adapting the WHO PPS design in inpatients departments in 2021. Among the 1417 enrolled patients, 52% were female and 63% were from the 15–64 years age group. Nearly 78% of patients received at least one antibiotic during the survey period. Third-generation cephalosporins (44.6%), penicillins (12.3%), imidazoles (11.8%), aminoglycosides (7.2%), and macrolides (5.8%) were documented as highly used antibiotics. Overall, 64.0% of Watch, 35.6% of Access, and 0.1% of Reserve group antibiotics were used for treatment. The use of Watch group antibiotics was high in medicine wards (78.7%) and overall high use of Watch antibiotics was observed at secondary hospitals (71.5%) compared to tertiary hospitals (60.2%) (p-value of 0.000). Our PPS findings underscore the need for an urgent nationwide antibiotic stewardship program for physicians including the development and implementation of local guidelines and in-service training on antibiotic use.

Bangladesh reported the first three laboratory-confirmed COVID-19 cases on March 8, 2020 in Dhaka and Narayanganj cities. As of April 8, 2020, 218 confirmed cases across the country, they have mostly detected from Dhaka (56.4%) and Narayanganj (21%) cities where the hotspots of an outbreak of COVID-19 disease. There were 6 cases in Dhaka district excluding metropolitan areas and rest of 43 (20%) cases in the 19 other regions. Local government-enforced completely shut down the hotspots areas on April 8 2020. However, peoples from hotspots travelled openly to the other districts. We aimed to understand the risk of open movement from hotspots. We studied 40 individuals who were infected with SARS-CoV-2 virus later at their destination. We developed a route map and density maps using Geographic Information System (GIS). Among the studied people, the average distance was 140.1 (75.1) kilometers (Km), and the range of distance was from 20.3 to 321.7 kilometers. Among them, 42.5% traveled <100 Km, 40.0% traveled between 100 and 200 Km and 17.5% traveled above 200 Km. Case numbers were increased 13.5 times more on April 20 than the cases as of April 8, 2020. Our analysis suggests that relaxed travel restriction could play an important role to spread COVID-19 transmission domestically. To reduce further spread of COVID-19, the government should closely monitor the public health intervention to stop the casual movement. [ABSTRACT FROM AUTHOR]

The WHO Essential Medicines List Access, Watch, and Reserve (AWaRe) classification could facilitate antibiotic stewardship and optimal use. In Bangladesh, data on antibiotic dispensing in pharmacies according to the AWaRe classification are scarce. We aimed to explore antibiotic dispensing pattern in pharmacies according to the WHO AWaRe classification to aid pharmacy-targeted national antibiotic stewardship program (ASP). From January to July 2021, we interviewed drug-sellers from randomly selected pharmacies and randomly selected customers attending the pharmacies. We collected data on demographics and medicines purchased. We classified the purchased antibiotics into the Access, Watch, and Reserve groups among 128 pharmacies surveyed, 98 (76.6%) were licensed; 61 (47.7%) drug-sellers had pharmacy training. Of 2686 customers interviewed; 580 (21.6%) purchased antibiotics. Among the 580 customers, 523 purchased one, 52 purchased two, and 5 purchased three courses of antibiotics (total 642 courses). Of the antibiotic courses, the Watch group accounted for the majority (344, 53.6%), followed by the Access (234, 36.4%) and Reserve (64, 10.0%) groups. Approximately half of the antibiotics (327/642, 50.9%) were purchased without a registered physician's prescription. Dispensing of non-prescribed antibiotics was higher in the Access group (139/234, 59.4%), followed by Watch (160/344, 46.5%) and Reserve (28/64, 43.8%) groups. These findings highlight the need to implement strict policies and enforce existing laws, and pharmacy-targeted ASP focusing on proper dispensing practices to mitigate antimicrobial resistance in Bangladesh.
