West Nile Bird Deaths Nearly Double

Late summer is typically the peak of West Nile virus season

So far this year San Diego County has collected nearly twice as many dead and infected birds due to the West Nile virus as they did in all of 2014, officials reported Tuesday.

The County Department of Environmental Health’s Vector Control program has collected 75 dead infected birds so far this year. Last year, 41 dead infected birds and six mosquito batches were collected, according to the county's news website.

County officials will drop larvicide on wetlands Wednesday.

It will be the sixth time this year helicopters will be used to drop batches of larvicide with a bacterium that kills mosquito larvae but doesn’t hurt people and pets, officials said.

So far, there have been no reported cases of West Nile in humans.

Last year, 11 people in San Diego were diagnosed with the virus, which is the largest number since 2009. Two people were killed by the illness.
