West Nile has surfaced in Chatham-Kent.
According to CK Public Health, mosquitoes collected from a trap in Ridgetown and tape in southeast Chatham collected on July 30 have been confirmed to have the virus.
While no human cases have been reported, Public Health staff say these are the first positive pools identified in Chatham-Kent this season from these traps.
West Nile Virus is transmitted to people through the bite of an infected mosquito. Many people infected with the virus experience no symptoms. Some may experience mild symptoms such as fever, headache, body aches and fatigue. In rare cases, infected individuals may experience more severe illness, including stiff neck, nausea, difficulty swallowing, vomiting, and paralysis. Anyone with severe symptoms should seek immediate medical attention. Older individuals and those with compromised immune systems are at higher risk of severe illness.
West Nile Virus is a risk anytime mosquitoes bite. Protect yourself and your family by:
- Wearing light-coloured clothing, including long-sleeved shirts, long pants, and socks
- Using insect repellent containing DEET (follow the label directions)
- Staying indoors when mosquitoes are most active (dusk to dawn)
- Ensuring that all door and window screens are tight and free of holes
- Eliminating sources of standing water on your property to prevent mosquito breeding
