Mosquito Pool in Cranford Tests Positive for West Nile Virus

Updates from Union County Bureau of Mosquito Control:

Union County Mosquito Control has four confirmed positive West Nile test results out of 63 mosquito pools submitted from the county so far this season. Two were in Clark, one in Summit and one in Cranford. They are certain that they will eventually get positive results in other parts of Union County as soon as they can trap there (rain postpones trapping).

The recent positive tests came from the corridor between Westfield Avenue and the Clark reservoir.

The Bureau will continue to monitor the areas that have positive pools of WNV mosquitoes, and, as they have continued to provide the services of nuisance and vector control to the residents of Union County for the past 100 years, take all of the steps employed by modern day mosquito control to subdue the populations of mosquitoes that invade our neighborhoods and parks. This can include barrier treatments, adulticiding, and larviciding. Most importantly, they urge residents to call them at 908-654-9834 if they are in need of mosquito services. They also advise residents to police their properties to rid any standing or stagnant water that may have accumulated undetected, which is what mosquitoes needs most to proliferate.

The Bureau sets portable mosquito traps at different locations throughout the mosquito season as a routine part of their surveillance program. In some cases, traps are set in locations where they are getting complaints of extreme populations of adult biting mosquitoes. Specimens are collected separated, identified, catalogued and submitted to the N.J. Department of Health and Senior Services - Public Health and Environmental Laboratories in Trenton.

The Bureau can't say what is "normal" for any given season due to all of the elements that vary from one season to the next. Some years the numbers of positive results can be more than any previous season and some years they can be lower. Weather plays a vital role in the number of pools that come back as positive. The Rutgers Center for Vector Biology tracks trends seasonally and yearly so an illustration can be seen for comparative results. Their website is   http://vectorbio.rutgers.edu/surveillance.php.

The Bureau advises residents to take the necessary precautions to avoid being bitten, as anyone contacting the virus may have a different reaction. Most people that are bitten by a mosquito carrying the West Nile Virus will show no symptoms at all, but when symptoms (i.e. flu like) do occur it is usually five to 15 days after being infected.

If you suspect that you may be infected, see your physician immediately. Less than 1% of the mosquito population in the areas tested carries the WNV. Less than 1% of the people bitten by an infected mosquito will become severely ill.
