Kerala's health authorities have issued a high alert following the death of a 70-year-old man from Kadungalloor, suspected to be due to West Nile fever. This incident marks the second reported death linked to this mosquito-borne disease in Ernakulam district within a week. In response, the Kerala Health Department has ramped up surveillance efforts and is urging residents to participate in mosquito-control initiatives to mitigate the risk of infection. West Nile fever, caused by the West Nile virus, is primarily transmitted through the bite of infected Culex mosquitoes and does not spread between humans. Symptoms can vary widely, from mild flu-like signs to severe complications affecting the nervous system, such as encephalitis and meningitis, which require urgent medical attention. Vulnerable populations include older adults, pregnant women, and individuals with weakened immune systems. Health officials recommend preventive measures, including the removal of stagnant water, use of mosquito repellents, and maintaining cleanliness around residential areas to curb mosquito breeding.
