West Nile fever: Health department in Ernakulam issues advisory

Kochi: In light of West Nile fever cases reported in some areas of the district, district medical office has advised public to exercise extreme caution. The flavivirus, commonly found in migratory birds, is transmitted to humans through mosquito bites and so steps should be taken for vector control, health department advisory states.

There is a report that a person from Kadungalloor in Aluva died in a suspected case of West Nile fever. At the same time, health department officials said they are yet to test samples of the deceased and confirm the cause of death. “West Nile disease does not spread from an infected person to others. Avoiding mosquito bites is key to preventing the disease. Symptoms may include fever, high body temperature, difficulty moving the neck, unusual changes in behaviour or demeanour of the feverish person, semi-consciousness or unconsciousness. If the disease becomes severe, it can affect nervous system, potentially leading to encephalitis or meningitis. Therefore, seeking immediate medical attention upon noticing symptoms is crucial. Elderly individuals, those with weakened immune systems, people with underlying health conditions, pregnant women and children should be particularly vigilant,” the advisory states.

Culex mosquitoes, which are vectors of West Nile virus, are commonly found in stagnant and non-flowing water, ditches, septic tanks, marshy areas and fields with overgrown grass. Mosquitoes also breed in places where water collects, such as tyres and containers. Therefore, adhering to preventive habits to avoid mosquito bites and conducting weekly mosquito eradication and source elimination activities are key preventive measures. “Take extra care to avoid mosquito bites during early morning and evening hours when the risk is higher. Be cautious both indoors and outdoors. Wear light-coloured clothing that covers arms and legs when going outside. Apply mosquito repellent properly. Ensure that clothes are not piled up in bedroom. Install nets on windows and doors to prevent mosquito entry. Use mosquito nets while sleeping,” the advisory states.
