City wraps up 2005 West Nile surveillance

News Nov 22, 2006 Flamborough Review

The City of Hamilton has concluded its 2005 West Nile virus surveillance program.

The risk of contracting West Nile virus from an infected mosquito has dropped substantially in recent weeks, due to the drop in daytime and nighttime temperatures. The surveillance program included trapping and testing adult mosquitoes for the West Nile virus, collecting mosquito larvae (developing mosquitoes) from catch basins and surface waters, tracking and testing dead birds, and tracking and investigating human cases.

In addition to surveillance activities, in 2005, the City of Hamilton also continued control strategies, including:

the completion of four catch basin treatments

performing more public land surface water investigations and treatment to reduce breeding areas

the investigation of 218 standing water complaints on properties and enforcement of the Standing Water By-law

As of October 31, the number of dead bird reports across the city was 904; of 60 submitted for testing, 33 came back negative, 12 were triaged and 15 tested positive.

Two mosquito pools (each representing a group of one species from a mosquito trap) tested positive in 2005, and one human case of West Nile virus was documented.
