in what may be the country's most lethal wave of the disease in recent history.  The campaign, which began on Sunday, comes amid more than 7,500 suspected measles cases since 15 March, according to health ministry data. More than 900 of these cases have been confirmed - a sharp increase from 2025, when just 125 measles cases were recorded over the entire year, local media report. While Bangladesh has long vaccinated children against the highly contagious disease, the recent outbreak has exposed gaps in its programme, raising concern. "Vaccines are foundational to child survival", Rana Flowers, the Unicef representative in Bangladesh, said in a statement on Sunday, adding that the current measles outbreak was "putting thousands of children, especially the youngest and most vulnerable, at serious risk".
