Warren County Mosquito Control Commission Update

 

West Nile Virus Detected in Liberty

 

One sample of Culex mosquitoes collected from Liberty has tested positive for West Nile virus. The mosquito sample was collected from Lakeside Drive W by the Mountain Lake beach parking lot on August 6, 2024.  The mosquitoes were collected from a trap specifically designed to catch Culex mosquitoes, which are the type responsible for transmitting West Nile virus, particularly from bird to bird. This sample of mosquitoes was sent to the state Public Health and Environmental Lab in Trenton on Monday, August 12, 2024.  

 

This is the first sample of mosquitoes from Liberty Township to test positive for West Nile virus in 2024; however, there has been a total of 19 samples of mosquitoes so far this year to test positive for West Nile virus from Warren County. To date, there have been positive samples in the following municipalities: Allamuchy (1), Alpha (3), Belvidere (1), Franklin (1), Hackettstown (2), Harmony (1), Liberty (1), Lopatcong (3), Oxford (1), Phillipsburg (4), and Washington Township (1). As the summer season progresses, West Nile virus activity builds up in the mosquito population.  West Nile virus activity in mosquitoes in NJ is trending higher this year than the 5-year average.  Mid to late August is the peak time for humans and other mammals to acquire this virus. There have been 2 confirmed human cases of West Nile Virus in New Jersey, one each in Union and Middlesex counties. Subsequent trapping for adult mosquitoes is taking place to survey for mosquito species more likely to bite people.  Treatments to reduce adult mosquito populations in that area are scheduled for Friday, August 16, 2024, between 8:30 pm and 11:00 pm (alternate date of Saturday, August 17, 2024).  Check our website for updates.

 

Residents are urged to help reduce their risk of contracting mosquito-borne diseases by following these guidelines: 

  • Don't produce mosquitoes on your property. Dump or drain standing water. Mosquitoes can't begin their life without water.
  • Defend yourself against mosquitoes using repellents containing DEET, Picaridin, or Oil of Lemon Eucalyptus.
  • Avoid being outdoors when mosquitoes are present, typically Dawn and Dusk.
  • Report neglected swimming pools by calling 908-453-3585 or visiting www.warrencountymosquito.org  Anonymous calls accepted. Just one neglected pool

      can produce more than 1 million mosquitoes and affect people up to five miles away.  

 

WEST NILE VIRUS INFORMATION

West Nile virus symptoms of the mild form include fever, headache, tiredness, body aches, and swollen lymph glands. While the illness can be as short as a few days, even healthy people have reported being sick for several weeks. 

Less than one percent of individuals (about 1 in 150 people) infected with West Nile virus will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent. West Nile virus infection can be fatal.
