The Kerala government has instructed all districts to remain vigilant following reported cases of West Nile fever in three districts of the state. Health Minister Veena George confirmed that the fever, transmitted by Culex mosquitoes, has been identified in Thrissur, Malappuram, and Kozhikode districts.

The Minister directed all districts to take necessary measures for mosquito control and urged the public to seek immediate treatment if experiencing symptoms such as headache, vomiting, muscle aches, and itching. She emphasized that symptomatic treatment and prevention are crucial in addressing the spread of the fever, as there is currently no medicine or vaccine available against the virus. The fever was first detected in Kerala in 2011.
