West Nile Virus Outbreak Slows, But Remains A Threat

FAIRFAX, Va. (November 1, 2012) – As of October 30, a total of 4,891 cases of West Nile virus disease in people, including 223 deaths, have been reported to the Centers for Disease Control and Prevention (CDC). The outbreak appears to be slowing, as the total number of new cases this week is down about 30 from the week before, according to CDC data.

Adult mosquito populations should continue to decline in the coming weeks as cooler weather moves in, but experts from the National Pest Management Association (NPMA) urge people to remain cautious as West Nile virus still remains a threat.

While mosquitoes tend to die off after the first hard frost of the season, this blood-sucking pest has several overwintering strategies to ensure that offspring survive a potential cold spell. In fact, eggs from floodwater mosquitoes can remain viable for up to seven years.

Homeowners are encouraged to remove any standing water on the property and stay indoors at dawn and dusk when mosquitos are at peak activity.
