Bangladesh Measles Outbreak

Bangladesh has recorded 336 child deaths since 15 March 2026 in a measles outbreak, with more than 50,000 confirmed and suspected cases by 8 May 2026. The outbreak has affected 58 of 64 districts across all eight divisions, and the Directorate General of Health Services has reported cases among children mainly in the 1 to 14 years age group.

Measles as a Viral Disease

Measles is a highly contagious viral disease caused by the measles virus, which belongs to the genus Morbillivirus in the family Paramyxoviridae. The disease spreads through respiratory droplets and airborne transmission, and it commonly affects children in areas with low vaccination coverage.

Case Load and Mortality Pattern

Between 15 March and 14 April 2026, Bangladesh reported 19,161 suspected measles cases and 2,897 laboratory-confirmed cases. During the same period, 166 measles-related deaths were recorded, with a case fatality rate of 0.9 per cent, and 79 per cent of the deaths were among children under five years of age. On 4 May 2026, Bangladesh recorded 17 child deaths in a single day, which was the highest daily toll during the outbreak. On 8 May 2026, 12 more children died within 24 hours, including six deaths in the Dhaka division.

Vaccination and Surveillance Measures

A targeted measles-rubella (MR) vaccination campaign began on 5 April 2026. By 8 May 2026, nearly 17 million children had received the vaccine, and officials expected another 18 million doses by 10 May 2026. MR1 and MR2 vaccine coverage declined during 2024-2025 because of a nationwide stockout of MR vaccine and disruptions in vaccine procurement processes during an interim administration. These gaps in routine immunisation increased the number of susceptible children in multiple age groups.

Diagnostic and Public Health Challenges

A shortage of measles testing kits has disrupted diagnostic services across Bangladesh. The Institute of Public Health has reported a backlog of thousands of samples, and this has affected laboratory confirmation of suspected cases.

Important Facts for Exams

• Measles is a vaccine-preventable disease, and the measles-rubella vaccine is used in routine immunisation programmes.
• The measles virus belongs to the family Paramyxoviridae and the genus Morbillivirus.
• Children under five years of age formed 79 per cent of the measles-related deaths in Bangladesh during the reported period.
• Bangladesh has eight administrative divisions and 64 districts.

Public Health Context

Measles outbreaks are monitored through suspected case reporting, laboratory confirmation, and vaccination coverage data. The World Health Organization classifies measles as a major cause of vaccine-preventable illness and death among young children in countries with immunity gaps.
