Background: Cholera increases the risk of harmful effects on foetuses. We prospectively followed pregnant women unaware of their pregnancy status who received a study agent in a clinical trial evaluating the association between exposure to an oral cholera vaccine (OCV) and foetal survival.

Methods: Study participants were selected from a randomized placebo-controlled trial conducted in Dhaka, Bangladesh.

Background: Vibrio cholerae, the causative agent of cholera, is a major cause of diarrhea worldwide. Children under the age of 5 have the highest disease burden of cholera. Vibriocidal antibody responses following natural infection and oral cholera vaccination (OCV) are associated with protective immunity, but whether this holds uniformly true in young children is not known.

Bangladesh has historically been cholera endemic, with seasonal cholera outbreaks occurring each year. In collaboration with the government of Bangladesh, the Infectious Diseases Division, International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) initiated operational research to test strategies to reach the high-risk urban population with an affordable oral cholera vaccine (OCV) "ShancholTM" and examine its effectiveness in reducing diarrhea due to cholera. Here we report a sub-analysis focusing on the organization, implementation and effectiveness of different oral cholera vaccine delivery strategies in the endemic urban setting in Bangladesh.

: Cholera is a considerable health burden in developing country settings including Bangladesh. The oral cholera vaccine (OCV) is a preventative tool to control the disease. The objective of this study was to describe whether the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b), could provide the OCV to rural communities using existing government infrastructure.

Background: Pregnant women are vulnerable to complications of cholera. Killed oral cholera vaccines (OCV) are not recommended for pregnant women though there is no evidence of harmful effects during pregnancy. We evaluated the effect of a killed OCV, Shanchol™, on pregnancy outcomes during an effectiveness trial of the vaccine in urban Bangladesh.

Background: In Bangladesh, 24 % of the total populations are adolescents. Twelve months intervention was implemented under Demand-Based Reproductive Health Commodity Project (DBRHCP) in two low performing areas: rural Sub-district Nabiganj (population 323,357) and an urban slum in Dhaka city (population 141,912). We evaluated the changes in knowledge of female unmarried adolescents on selected reproductive health issues over the project period in two low performing areas of Bangladesh.

Background: Cholera is endemic in Bangladesh with epidemics occurring each year. The decision to use a cheap oral killed whole-cell cholera vaccine to control the disease depends on the feasibility and effectiveness of vaccination when delivered in a public health setting. We therefore assessed the feasibility and protective effect of delivering such a vaccine through routine government services in urban Bangladesh and evaluated the benefit of adding behavioural interventions to encourage safe drinking water and hand washing to vaccination in this setting.

The oral cholera vaccine (Shanchol), along with other interventions, is a potential new measure to prevent or control cholera. A mass cholera-vaccination programme was launched in urban Dhaka, Bangladesh, during February-April 2011 targeting about 173,041 people who are at high risk of cholera. This cross-sectional, descriptive study assessed the coverage and acceptability of the vaccine.

Purpose: The reproductive health needs of unmarried adolescents in Bangladesh are largely unmet. This study aimed to explore treatment-seeking behaviour of unmarried female adolescents for selected reproductive health (RH) concerns in two low-performing areas of Bangladesh.

Methods: As part of a large community based-project, a cross-sectional survey was conducted from November 2006 to March 2007.

Background: Three-year duration Demand-Based Reproductive Commodity Project (DBRHCP) was launched in three low performing areas: rural Nabiganj (population 323,357), Raipur (population 260,983) and urban slum in Dhaka (population 141,912).

Objectives: Assessing changes in knowledge among married women of reproductive age on selected reproductive health issues and to explore their service utilization patterns over the project period in selected low performing areas of Bangladesh.

Methods: The study adopted a pre- posts design.

We explored the feasibility of distributing misoprostol tablets using two strategies in prevention of postpartum haemorrhage (PPH) among women residing in the Abhoynagar subdistrict of Bangladesh. We conducted a quasiexperimental study with a posttest design and nonequivalent comparison and intervention groups. Paramedics distributed three misoprostol tablets, one delivery mat (Quaiyum's delivery mat), a packet of five standardized sanitary pads, and one lidded plastic container with detailed counseling on their use.

Objective: The study was conducted to identify selected programmatic factors relating to low contraceptive-use in a low-performing rural sub-district in Sylhet division of Bangladesh.

Methods: A cross-sectional survey was carried out among 6983 currently-married women of reproductive age (MWRA) (15-49 years). To estimate the association between current contraceptive-use and other selected factors, multivariate analyse were performed, estimating the crude and adjusted odds ratios (OR), including 95% confidence intervals (CI).

Background: In endemic countries such as Bangladesh, consequences of cholera place an enormous financial and social burden on patients and their families. Cholera vaccines not only provide health benefits to susceptible populations but also have effects on the earning capabilities and financial stability of the family. Community-based research and evaluations are necessary to understand perceptions about and practices of the community relating to cholera and oral cholera vaccines.

Vibriocidal antibody is a marker of recent exposure to Vibrio cholerae O1 infection. We examined vibriocidal titers for 1 year after an episode of severe cholera in patients in Dhaka, Bangladesh; 16 of 53 (30%) patients had a fourfold or greater increase in vibriocidal titer between 6 and 12 months after an episode of severe cholera, suggesting reexposure to the organism. Among patients with rises in titers during follow-up, the patients initially infected with serotype Ogawa had earlier rises in titer than the patients initially infected with serotype Inaba.

The study was conducted to assess the impact of combined interventions to improve the child immunization coverage in rural hard-to-reach areas of Bangladesh. The valid coverage increased at endline compared to baseline in the study areas, and the difference of the increase was highly significant (p<0.001).

Background: In Bangladesh, increases in cholera epidemics are being documented with a greater incidence and severity. The aim of this prospective study was to identify the prevalence and importance of V. cholerae O1 and enterotoxigenic Escherichia coli (ETEC) as causal agents of severe diarrhea in a high diarrhea prone urban area in Dhaka city.

This article aimed to assess child immunization coverage in rural hard-to-reach hilly and low lying (haor) areas of Bangladesh. Status of fully immunized children was significantly lower in haor areas compared to hilly areas. Fully immunized children in both hilly and haor areas was significantly lower than concerned division as well as national level coverage.

This article assessed the status of childhood vaccination coverage and the possibility of using selected alternative vaccination strategies in rural hard-to-reach haor (low lying) areas of Bangladesh. Data were collected through survey, in-depth interviews, group discussion, and observations of vaccination sessions. Complete immunization coverage among 12- to 23-month-old children was found to be significantly lower in study areas when compared with the national coverage levels.

Background: Mobile population groups are at high risk for contracting HIV infection. Many factors contribute to this risk including high prevalence of risky behavior and increased risk of violence due to conflict and war. The Naf River serves as the primary border crossing point between Teknaf, Bangladesh and Mynamar [Burma] for both official and unofficial travel of people and goods.
