NJDOH, NJDEP Urge Precautions To Protect Against West Nile Virus

One Confirmed Death Attributed to Virus Reported in New Jersey

TRENTON – With New Jersey in the height of West Nile Virus (WNV) season, the state is reporting one confirmed death associated with the virus to date. The New Jersey Department of Health (NJDOH) and New Jersey Department of Environmental Protection (NJDEP) urge residents to take precautions to protect themselves from mosquito-borne diseases with steps to reduce mosquito populations on their properties.

New Jersey currently has 14 WNV human cases (3 confirmed, 11 probable) reported in the following counties: Bergen (2), Burlington (3), Camden (2), Essex, Gloucester, Middlesex, Passaic, Somerset, Ocean and Monmouth. NJDOH and local health departments are investigating an additional six WNV reports. In a typical year, there are eight WNV infections reported. WNV activity in mosquitoes is also high, with significantly more WNV positive mosquito pools identified this year compared to five-year averages.

The death of a Camden County man in his 60s who became ill in mid-July has been attributed to WNV neuroinvasive disease.  

The months of August and September are when most WNV cases are reported in the state.

“It is important to remind residents to continue to take precautions to protect themselves against mosquito bites,” NJDOH Commissioner Judith Persichilli said. “Using an insect repellant and avoiding being outdoors when mosquitos are active are just some of the steps residents can take to stay safe from mosquito-borne illnesses.”

West Nile Virus is a disease which people can acquire through the bite of a mosquito that has fed on an infected bird. WNV is not directly transmitted from birds to humans.

For many people, the virus causes asymptomatic infection or a mild to moderate illness typically with a fever. People over age 50 and people with weak immune systems are at greater risk of developing severe illness.  About one in 150 persons will develop a more severe form of the disease, with symptoms such as severe headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.

“We are seeing an increase in mosquitos at present due to the recent flooding from Ida,” said Department of Environmental Protection Commissioner Shawn M. LaTourette.  “DEP is working closely with every county’s mosquito control program and posting safety guidance for residents on our social media channels. New Jersey residents can help stay safe by making sure to remove any standing water in yards and to cover any empty containers that can hold water for more than three days.” 

To protect against mosquito borne diseases, residents should:

  • Apply EPA-registered insect repellant
  • Avoid being outdoors during dawn and dusk when mosquitos are most active
  • Wear long sleeves and long pants
  • Cover crib, stroller and baby carrier with mosquito netting
  • Repair holes in screens to keep mosquitoes outside and use air conditioning when possible

New Jersey's WNV surveillance, control, and prevention activities involve the coordinated efforts of a number of federal, state and local agencies including: NJDOH, NJDEP,  the New Jersey Department of Agriculture, the U.S. Centers for Disease Control and Prevention, the State Mosquito Control Commission, the Rutgers Center for Vector Biology, and local health and mosquito control agencies.
