Country: Bangladesh Source: European Commission’s Directorate-General for European Civil Protection and Humanitarian Aid Operations Bangladesh is experiencing a measles outbreak across 58 out of 64 districts. To date, 166 children have died (32 laboratory-confirmed) and 19,161 cases have been hospitalised (2,973 laboratory-confirmed). In Rohingya camps, 211 suspected cases have been reported (8 confirmed). The outbreak is driven by gaps in routine immunisation, with clusters of zero-dose and under-vaccinated populations, compounded by delays in the 2025 nationwide measles-rubella (MR) campaign. Pressure on the Bangladeshi health system is increasing, with overstretched laboratory capacity and limited availability of Vitamin A supplements. An emergency MR campaign began on 5 April, reaching 943,000 children (6 months–5 years) by 13 April. Around 22 million doses are being distributed. In Rohingya camps, vaccination will run from 26 April to 7 May, targeting 178,028 children. UN agencies, the BDRCS and NGOs are supporting vaccination preparedness, including volunteer mobilisation and awareness campaigns.
