RESUMO
BACKGROUND: Non-pharmaceutical interventions (NPIs) used to limit SARS-CoV-2 transmission vary in their feasibility, appropriateness and effectiveness in different contexts. In Bangladesh a national lockdown implemented in March 2020 exacerbated poverty and was untenable long-term. A resurgence in 2021 warranted renewed NPIs. We sought to identify NPIs that were feasible in this context and explore potential synergies between interventions. METHODS: We developed an SEIR model for Dhaka District, parameterised from literature values and calibrated to data from Bangladesh. We discussed scenarios and parameterisations with policymakers with the aid of an interactive app. These discussions guided modelling of lockdown and two post-lockdown measures considered feasible to deliver; symptoms-based household quarantining and compulsory mask-wearing. We compared NPI scenarios on deaths, hospitalisations relative to capacity, working days lost, and cost-effectiveness. RESULTS: Lockdowns alone were predicted to delay the first epidemic peak but could not prevent overwhelming of the health service and were costly in lost working days. Impacts of post-lockdown interventions depended heavily on compliance. Assuming 80% compliance, symptoms-based household quarantining alone could not prevent hospitalisations exceeding capacity, whilst mask-wearing prevented overwhelming health services and was cost-effective given masks of high filtration efficiency. Combining masks with quarantine increased their impact. Recalibration to surging cases in 2021 suggested potential for a further wave in 2021, dependent on uncertainties in case reporting and immunity. CONCLUSIONS: Masks and symptoms-based household quarantining synergistically prevent transmission, and are cost-effective in Bangladesh. Our interactive app was valuable in supporting decision-making, with mask-wearing being mandated early, and community teams being deployed to support quarantining across Dhaka. These measures likely contributed to averting the worst public health impacts, but delivering an effective response with consistent compliance across the population has been challenging. In the event of a further resurgence, concurrent messaging to increase compliance with both mask-wearing and quarantine is recommended.

Poor health care-seeking behaviour, access to services and availability of service delivery have implications for the health of the community. This study explored the perceptions, practices and challenges related to maternal and neonatal care in the teagarden community in Bangladesh. The study also identified service gaps and problems prevalent in teagarden health facilities. A qualitative study was conducted in five teagardens in the Moulvibazar district of Bangladesh. Six focus group discussions (FGDs) were completed with individuals from the teagarden community, and twelve in-depth interviews (IDIs) were performed with health facility staff working in those teagarden facilities. Misconceptions and harmful traditional practices were found to exist among the families in the teagardens, restricting them from accessing quality health care. Pregnant women are not aware of antenatal care, and deliveries are being conducted at home by untrained birth attendants. Unhygienic and harmful postnatal practices are used. Teagarden health facilities are not well equipped or prepared to provide good care. Inequities exist within the teagarden communities, with unregistered workers having even poorer access to care. Improvement of the quality of maternal health care for this marginalised community is needed to progress maternal health.
