Human case of West Nile virus confirmed in the Algoma District

After a crow tested positive for West Nile virus, Algoma Public Health says a human case has also been confirmed.

"These events are a reminder that (the virus) is present in our communities and there is an ongoing risk to residents during peak mosquito season," the health unit said in a news release.

"Algoma Public Health urges members of the community to take steps to limit their risk and to seek medical assessment if they are concerned that they may have symptoms."

Mosquitoes acquire the virus by feeding on infected birds and then pass the virus to humans and other mammals when they feed on them.

The last time West Nile was confirmed in Algoma was in 2018 when mosquitoes taken from a trap tested positive. The health unit conducts monitoring across the district every year.

"Algoma Public Health traps mosquitoes throughout the summer to send them for species identification and … testing," Chris Glibota, a public health inspector, said in the release.

"Although the risk of becoming infected … is low, protecting yourself against mosquito bites can help reduce the risk even further."

To prevent mosquito bites, the health unit recommends residents:

• Wear light-coloured clothing, long-sleeved shirts, long pants, socks, and shoes when outdoors.
• Use insect repellent containing DEET or Icaridin, and follow the directions carefully.
• Avoid the outdoors at dusk and dawn when mosquitoes are most active.
• Repair or replace screens on windows and doors to avoid mosquitoes entering your home.
• Remove standing water from your property where mosquitoes can breed.

People who are older or who have a weakened immune system have a greater chance of having a severe illness if they contract the virus.

"Most people who contract West Nile virus will not feel any symptoms," Algoma Public Health said.

"About one in five people infected may experience mild illness including fever, headache, body ache, nausea, vomiting, and rash on the chest, stomach or back."

Severe symptoms can include muscle weakness, stiff neck, confusion, tremors, numbness and sudden sensitivity to light. Symptoms usually develop between two to 15 days after being bitten by an infected mosquito.

If you think you may have contracted West Nile virus, contact your doctor or other health care provider.

"Algoma Public Health does not accept dead birds," the release said.

"If you find a dead bird on your property, you can contact the Canadian Wildlife Health Cooperative to learn more about their surveillance and submission programs."
