Hepatitis E and A Spread Through Contaminated Food and Water in Bangladesh

Hepatitis viruses are prevalent in the environment, particularly in food and water sources in Bangladesh, leading to jaundice with minimal carelessness. Hepatitis E accounts for 37% of waterborne jaundice hospitalizations in the country, while Hepatitis A affects approximately 27% of at-risk individuals. The high transmission rates of Hepatitis A and E are exacerbated during warmer months and the monsoon season. This surge is attributed to urban waterlogging during monsoons, which causes sewage lines to mix with water supply pipelines, contaminating drinking water. Additionally, increased consumption of unsafe street beverages like juices and sugarcane drinks by outdoor workers during hot weather contributes to the spread. Poor waste management and a lack of sanitary toilets in densely populated and impoverished areas further worsen the situation. Contrary to popular belief, Hepatitis A and E can have severe consequences, including liver failure and death, especially in pregnant women. A 2016 study identified Hepatitis E infection during pregnancy as a significant risk factor for maternal mortality in Bangladesh. To prevent infection, individuals should avoid open, unsafe beverages and always drink purified water. Water at home must be boiled, cooled, and stored in clean containers, with boiled water recommended for washing during monsoon season. Street vendors selling juices, sugarcane drinks, and other iced beverages are significant sources of infection, as are restaurants that may use contaminated water for washing dishes and produce. Consumers should also be cautious about the purity of bottled water. In flood-affected areas, providing safe drinking water or implementing water purification measures is crucial. Promoting good hygiene practices, such as regular handwashing with soap, from childhood and making hygiene education mandatory in schools are essential preventive measures.
