Measles outbreak infects infants in Chattogram linked to single B3 strain
Researchers examined 300 children aged two months to 11 years during a measles outbreak in the Chattogram division and found 46% were under the nine-month age for routine MR vaccination and 65.7% (197) had received no measles vaccine. Whole-genome sequencing of 17 samples showed a single B3 genotype in all cases, clarifying transmission. Nutritional deficits and missed vitamin A correlated with severe disease, and maternal vaccination status associated with outcomes. The team recommended six-month outbreak dosing in high-risk areas, follow-up routine doses, boosted routine coverage, catch-up campaigns, maternal vaccination and stronger hospital infection controls.
Nearly half of infected children were too young for routine vaccination
