West Nile shows up in Mitchell

The Beacon Herald - - NEWS - BEA­CON HER­ALD STAFF

A mos­quito in Mitchell has tested pos­i­tive for West Nile virus.

The Perth District Health Unit says this is the first pos­i­tive test in Perth County this sea­son.

“West Nile virus ac­tiv­ity has been low so far across On­tario, but it’s not sur­pris­ing to see ac­tiv­ity be­gin to in­crease as his­tor­i­cally we get pos­i­tive mos­quito pools around this time,” pub­lic health in­spec­tor Stephanie Carlisle said in a press re­lease.

The health unit has been trap­ping and test­ing mosquitoes since June. Staff also ap­plied one round of lar­vi­cide in road­side catch basins in Strat­ford, St. Marys, Lis­towel and Mitchell to help re­duce mos­quito breed­ing. A sec­ond round was sched­uled for early Au­gust.

There have been four prob­a­ble or con­firmed cases of West Nile virus in hu­mans re­ported this year, ac­cord­ing to the health unit. Typ­i­cal symp­toms – not all peo­ple bit­ten by in­fected mosquitoes will show symp­toms – in­clude fever, headache, body ache, nau­sea, vom­it­ing and rashes. In some cases, symp­toms in­clude high fever, mus­cle weak­ness, vi­sion loss and coma. They usu­ally de­velop be­tween two and 15 days af­ter be­ing bit­ten by an in­fected mos­quito.
