In 2023, Bangladesh experienced its largest and deadliest outbreak of the Dengue virus (DENV), reporting the highest-ever recorded annual cases and deaths. Historically, most of the cases were recorded in the capital city, Dhaka. We aimed to characterize the geographical transmission of DENV in Bangladesh. From 1 January–31 December 2023, we extracted and analyzed daily data on dengue cases and deaths from the Management Information System of the Ministry of Health and Family Welfare. We performed a generalized linear mixed model to identify the associations between division-wise daily dengue counts and various geographical and meteorological covariates. The number of dengue cases reported in 2023 was 1.3 times higher than the total number recorded in the past 23 years (321,179 vs. 244,246), with twice as many deaths than the total fatalities recorded over the past 23 years (1705 vs. 849). Of the 1,705 deaths in 2023, 67.4% (n = 1,015) died within one day after hospital admission. The divisions southern to Dhaka had a higher dengue incidence/1000 population (2.30 vs. 0.50, p <0.01) than the northern divisions. Festival-related travel along with meteorological factors and urbanization are likely to have contributed to the shift of dengue from Dhaka to different districts in Bangladesh.

We use childhood exposure to disasters as a natural experiment inducing variations in adulthood outcomes. Following the fetal origin hypothesis, we hypothesize that children from households with greater famine exposure will have poorer health outcomes. Employing a unique dataset from Bangladesh, we test this hypothesis for the 1974–75 famine that was largely caused by increased differences between the price of coarse rice and agricultural wages, together with the lack of entitlement to foodgrains for daily wage earners. People from northern regions of Bangladesh were unequally affected by this famine that spanned several months in 1974 and 1975. We find that children surviving the 1974–75 famine have lower health outcomes during their adulthood. Due to the long-lasting effects of such adverse events and their apparent human capital and growth implications, it is important to enact and enforce public policies aimed at ameliorating the immediate harms of such events through helping the poor.

South of 25°N, the rugged, riparian, mixed evergreen forests of eastern Bangladesh mark the western edge of the ranges of the globally Vulnerable Asiatic black bear Ursus thibetanus and sun bear Helarctos malayanus. According to the IUCN Red List, the distribution of bears in Bangladesh is unclear: black bears are described as ‘scattered’ and ‘likely to be very low in number’ and sun bears as ‘vagrants’ entering from the adjoining north-east Indian forests. These statements are not based on any population or habitat assessments, impeding focused research and conservation investment. We compiled recent evidence of bear presence in Bangladesh based on camera trapping, literature reviews and analysis of media reports. From peer-reviewed and grey literature published during 2010–2022 we traced 43 verifiable accounts of black bears in the country. Our camera-trap survey in Rajkandi Reserve Forest produced the first ever evidence of a small population of black bears in north-eastern Bangladesh. Two field studies (in 2016 and 2021) reported camera-trap observations and multiple incidents of poaching of sun bears in Kassalong Reserve Forest and Sangu-Matamuhuri Reserve Forest in south-eastern Bangladesh. Media reports on conflict incidents presented 83 human casualties (80 injured, three dead) and 13 bear casualties (six dead, seven rescued) during 2003–2023. The incidents peaked in the summer (17); 79% were reported during 2018–2023. Cognizant of the fact that the absence of evidence is not evidence of absence, our study calls for systematic conservation measures for both of these bear species in unprotected hill forests in eastern Bangladesh.

This empirical study examines the potential and the obstacles of transitional justice in addressing the denial of the Rohingya genocide in Myanmar (also known as Burma). It utilizes a qualitative research approach, drawing on relevant scholarship of truth-seeking as a transitional justice mechanism, criminology and international law. Empirical data were collected through in-depth interviews with victims of the Rohingya community and key informants in two separate stages between 2022 and 2023. This study presents an interdisciplinary approach to assess the role of a truth commission – a truth-seeking tool – in confronting Myanmar’s denial of this crime. It suggests that examining amnesties, as well as disarmament, reintegration and rehabilitation programmes for the individual perpetrators within the framework of a truth commission can provide a more nuanced discourse of addressing the decades-long denial of the Rohingya genocide in Myanmar.

This study investigates the stigma against people with mental illness in Bangladesh through in-depth interviews with 14 patients and 9 healthcare professionals, and 33 focus group discussions with people without mental illness. The research has delved into the understanding of different types of stigma against mental illness in the context of Bangladesh. The findings revealed four types of stigma which were categorized into four themes namely self-stigma, public stigma, professional, and institutional stigma. Patients had internalized negative attitudes, thereby discriminated toward themselves. The public discriminated against patients because of believing in prejudices against them. Other health professionals had negative conceptions toward patients, and they devalued mental health professionals (MHPs). A culture of negative attitude and belief had emerged in institutional settings which encouraged discrimination. Policymakers and healthcare professionals can use the findings to develop a mental health service by addressing the stigma. Mental health practitioners can assess the impact of stigma to improve the mental well-being of their patients. Students and workplace staff will benefit from intentional or unintentional discrimination in educational institutions and workplace settings by addressing the effects of stigma. Importantly, other health care providers will be aware of their thoughts against patients and MHPs.

Toxocara vitulorum is one of the deadliest parasite of buffalo calves in Bangladesh. This study was conducted to explore genetic variability within and among the T. vitulorum populations in buffalo calves of Bangladesh. Genomic DNA was extracted, ITS2, COX1 and NAD1 gene were amplified and sequenced. Distinct 29 ITS2, 21 unique NAD1 and 24 COX1 genotypes were detected among the T. vitulorum of different geographic regions. These three gene genotypes similarities ranged from 97 to 99%, when these were compared to best hit scoring T. vitulorum sequences retrieved from GenBank. A total of 12 and 6 unique haplotypes were detected for COX1 and NAD1 gene sequences. The average nucleotide and haplotype diversity for COX1 and NAD1 were 0.0931 & 0.89493 and 0.00658 & 0.77895 respectively and the recorded values were more dispersed than previously published values. The pairwise Nst values ranged from −0.050 to 0.602 and Fst from −0.050 to 0.600 between all the T. vitulorum genotypes indicated huge genetic differentiation which were reportedly higher than other published reports Fst values. This is the first report of T. vitulorum on the basis of COX1 gene in Bangladesh. The study findings will be helpful for further extensive epidemiological studies regarding anthelmintic resistance, control and prevention of T. vitulorum infection in buffalo calves.

Bangladesh is experiencing a rapid increase in hypertension prevalence, particularly in socio-economically disadvantaged communities. The higher use of solid fuel in these communities could be one of the significant factors contributing to this trend, but evidence supporting this hypothesis is limited in Bangladesh. Therefore, this study aims to investigate the associations of household solid fuel use and its exposure level with systolic and diastolic blood pressure (DBP) and hypertension. We analysed 7,320 women’s data from 2017/18 Bangladesh Demographic and Health Survey. We considered three outcome variables: (i) systolic blood pressure (BP) (continuous response), (ii) DBP (continuous response), and (iii) hypertension status (yes, no). Our primary exposures of interest were fuel type (clean vs solid) and the potential level of household air pollution exposure through solid fuel use (unexposed, moderately exposed, and highly exposed). We used a multilevel mixed-effects Poisson regression model with robust variance to determine association between exposure and outcome variables while adjusting for confounders. Of the total respondents analysed, approximately 82% used solid fuel for cooking. The age-standardised prevalence of hypertension was 28%. Respondents using solid fuel were found to be 1.44 times (95% confidence interval [CI], 1.04–1.89) more likely to develop hypertension compared to clean fuel users. Compared to women using clean fuel, the likelihood of hypertension was found to be 1.61 times (95% CI, 1.07–2.20) higher among the moderately exposed group and 1.80 times (95% CI, 1.27–2.32) higher among the highly exposed group. Similar associations were reported for systolic and DBP. The use of solid fuel increases the risk of becoming hypertensive and elevates systolic and DBP. Policies and programmes are necessary to increase awareness of the adverse effects of solid fuel use on health, including hypertension. Efforts should be made to reduce solid fuel use and ensure proper ventilation systems in households where solid fuel is used.

The Muslims of South Asia are more than five hundred million people, distributed between Pakistan, India, and Bangladesh, and there are more Muslims in South Asia than in any other region in the world. After Indonesia, which is the largest Muslim country in the world, India, Pakistan, and Bangladesh are the second, third, and fourth largest Muslim countries, respectively. Although the prevalent approach in the study of Islam is to consider its so-called Arab character as central, the Muslims in pre-Partition India constituted the largest body of Muslims in the world, and the vast political and intellectual influence exerted by South Asian Muslims on the wider Muslim world is often neglected. Many of the most important political, intellectual, and spiritual developments within Islam have had their origins, or have flourished, in South Asia, and Muslims from the region have played important roles in the global history of Islam, including during the colonial period, in resistance to colonial rule, and in intellectual responses to and dialogue with Western thought. Pakistan was specifically created to provide a homeland for South Asia’s Muslim population and its trials and tribulations over the past seventy-five years have been carefully watched by Muslims and non-Muslims alike. Muslims constitute India’s largest minority, with an often uneasy—to say the least—relationship to the majority. In the context of the three books under discussion, I explore issues, such as secularism, modernity, and religion, and their impacts on the conception of the nation-state that was promoted during the nineteenth and twentieth centuries as an expression of political modernity.

Indigenous people worldwide are at increased risk of mental health problems compared with non-Indigenous people. Longstanding impacts of colonisation, systematic exclusion from rights and subsequent discrimination, and lack of access to quality education and healthcare, including mental healthcare, have been identified as contributory factors to these disproportionate mental health problems. With limited access, Indigenous people are less likely to seek healthcare, owing to the insufficient number of healthcare professionals representing Indigenous communities. In the face of growing numbers of mental health problems in Indigenous people in Bangladesh, this paper sheds light on the inadequate number of mental health professionals, particularly from Indigenous communities, and the potential impacts of this on the well-being of Indigenous people, and considers ways to increase representation of Indigenous mental health professionals. The aim is to ensure that the mental health system in Bangladesh is inclusive and embraces the country's diversity.

This study explores Bangladesh’s mental health services from an individual- and system-level perspective and provides insights and recommendations for strengthening it’s mental health system. We conducted 13 in-depth interviews and 2 focus group discussions. Thirty-one participants were recruited using a combination of purposive and snowball sampling methods. All interviews and group discussions were audio-recorded and transcribed, and key findings were translated from Bengali to English. Data were coded manually and analysed using a thematic and narrative analysis approach. Stakeholders perceived scarcity of service availability at the peripheral level, shortage of professionals, weak referral systems, lack of policy implementation and regulatory mechanisms were significant challenges to the mental health system in Bangladesh. At the population level, low levels of mental health literacy, high societal stigma, and treatment costs were barriers to accessing mental healthcare. Key recommendations included increasing the number of mental health workers and capacity building, strengthening regulatory mechanisms to enhance the quality of care within the health systems, and raising awareness about mental health. Introducing measures that relate to tackling stigma, mental health literacy as well as building the capacity of the health workforce and governance systems will help ensure universal mental health coverage.

This study assessed the trends in twin births and their survival in Bangladesh by analyzing over a quarter million live births during 1970–2018, pooled from all eight rounds of the Bangladesh Demographic and Health Survey. In these five decades, the twinning rate increased by 1.5 times, from 5.8 to 8.6 twins per 1000 maternities. The decadal twinning rates varied across maternal age, parity, body mass index, household wealth index, and geographic region. The gap in decadal neonatal, infant, and under-five cumulative survival probability between singleton and multiple births was found to be closing, using Kaplan-Meier curves. Child mortality decreased by 80% and 60% in singleton and multiple births respectively. However, the absolute size of child mortality in multiple births remained six times higher than in singletons and was concentrated in the neonatal period. The share of multiple births surged in all types of child mortality. We predict a further and faster rise in multiple births in the coming decades in the face of upward trends in maternal age overlapping with higher parities, education, career prospects, contraceptive use, and the future demand-supply of assisted reproductive technology. A particular focus on the improvement of perinatal and neonatal care with wider availability is warranted. Otherwise, increased multiple births might raise child mortality and create public health challenges.
