Virus Still Lurks Near New York City

By
WebMD Health News

March 9, 2000 (Atlanta) -- It's hard to forget the images of helicopters crossing the New York sky like so many of the marauding mosquitoes they were trying so hard to kill. Though there's no reason yet to believe the pesticide-spraying machines need to return, there is cause for concern about a resurgence of the West Nile virus they were trying to destroy.

The CDC has released a report stating that genetic traces of the virus have been detected in pools of hibernating mosquitoes at Fort Totten in New York, an area in Queens and just outside Manhattan. No live virus has been found yet, but the RNA found is a building block of the virus, and of enough concern to cause a flurry of news releases and press conferences to calm public anxiety.

As part of an ongoing prevention campaign, the mosquitoes were pooled together from areas in and around New York City based on locations of people and mosquitoes infected with West Nile Virus (WNV) during the outbreak of the disease last year. Seven people died then, and scores more were sickened by the virus, which causes encephalitis, an inflammation of the brain, in humans.

"Low but detectable levels" of WNV RNA were found in Fort Totten. Duane Gubler, ScD, of the CDC tells WebMD he wasn't surprised by the findings, but that "it will surprise us if we don't find [a live virus]." Gubler says, "It's fairly typical of these kinds of viruses that they will [hibernate] over winter."

Still, Gubler says this discovery "shouldn't be alarming. It's just another wake-up call that these things happen."

Following the outbreak last year, the departments of health in New York City and the state set up guidelines that included collecting the hibernating mosquitoes in affected areas to test for the virus in order to see whether another animal-borne outbreak like last year was in the making.

The WNV can be transmitted from mosquitoes to their offspring. If the mosquitoes grow and the virus lives, the transmission cycle may begin again. The mosquitoes bite birds, who then fly around, get bitten by more mosquitoes, who then bite humans, and so on. For most people, the virus is harmless, but for people over 50, and others whose immune system is weakened, WNV can be lethal. All seven deaths last fall were among people over age 75.
