Protect yourself against mosquitoes and WNV

The Halton Region Health Department would like to remind Halton residents to protect themselves against West Nile virus (WNV).

“Although West Nile virus has not been in the forefront of infectious diseases so far this summer, everyone still needs to continue to take precautions,” said Dr. Bob Nosal, Halton Region Medical Officer of Health. “July, August, and September are the months when we typically see mosquitoes test positive for West Nile virus.”

To protect yourself, avoid being outdoors between dusk and dawn, wear long-sleeved shirts and pants with tightly-woven fabric, and use a mosquito repellent with DEET. In shady, wooded areas, mosquitoes can be active all day and night.

Of those who become infected with WNV, 80 per cent will not have any symptoms. However, 20 per cent of those infected can have fever, nausea, muscle aches, headache and rash. In the rare severe cases, people can develop encephalitis or meningitis, which can lead to serious brain damage and even death. The risk for serious illness when infected with WNV increases as one gets older. Elderly persons and older adults need to pay particular attention to protecting themselves.

Residents are also asked to eliminate or reduce areas of standing water, which is where mosquitoes breed. These areas could be bird baths, old tires, low lying areas, and children’s play toys—anywhere water has accumulated and is able to stand for at least seven days.
