People at high risk for severe illness are encouraged to consider avoiding outdoor activity at dusk and dawn.
The health unit is advising people wear light-coloured long-sleeved shirts, long trousers, and closed-toe shoes in order to prevent bites.
"Only about 20 percent of the people infected will notice symptoms that may include headache, body aches, joint pains and fatigue", according to KCHD press release.
