Kerala on Alert After West Nile Fever Outbreak

The Kerala health department has sounded an alert in the districts of Thrissur, Malappuram, and Kozhikode after the detection of multiple cases of the mosquito-borne West Nile fever. Tragically, the outbreak has already claimed the life of a 79-year-old man in Thrissur.

West Nile virus, primarily transmitted through infected mosquito bites, can lead to a potentially fatal neurological disease in humans. However, around 80% of those infected do not exhibit any symptoms.

In response to this alarming situation, the state health minister has directed officials to intensify vector control measures and pre-monsoon cleaning activities in coordination with local authorities. Health officials have also been instructed to ramp up awareness campaigns and urge anyone with fever or other symptoms to seek immediate medical attention.

This is not the first time Kerala has faced the threat of West Nile fever. The state reported cases as early as 2011, and the disease has claimed lives in 2019 and 2022 as well. While there is no specific treatment or vaccine available, prompt action to control mosquito populations and early diagnosis can help mitigate the impact of this outbreak.

The health department’s proactive measures are crucial to containing the spread of West Nile fever and preventing further loss of life. Residents must cooperate by eliminating stagnant water sources and using protective measures against mosquito bites. With vigilance and a concerted effort, Kerala can overcome this public health challenge.
