BBC Bangladesh is battling its worse measles outbreak in years, with more than 100 children dead amid a rise in unvaccinated infants.
The government, in partnership with the United Nations, has begun conducting an emergency measles-rubella vaccination drive for children across the country, after more than 900 cases were confirmed since March.
Measles is a highly contagious airborne disease causing fever, respiratory symptoms and a characteristic rash and can sometimes have severe or fatal complications, especially in young children.
