Health officials in northeastern India have issued an alert after at least 15 people died from Japanese encephalitis in the past two weeks.
The top health official Dhruba Hojai in northeastern Assam said hundreds more are suffering from symptoms of the deadly disease, which has reached epidemic proportions in some areas of the state.
Officials are warning local health workers to be on the lookout for the disease and take preventative measures to stop it from spreading.
Japanese encephalitis is spread by mosquitoes that breed in water left from the annual monsoon season from June to September. The disease causes inflammation of the brain tissue, with symptoms of high fever and seizures.
Authorities in the state have launched a massive vaccination campaign against the disease.
