High number of mosquitoes found with West Nile virus 


 

Surveillance results concern health officials

The Kent County Health Department held an urgent news conference Wednesday to help get the word out that an unusually high number of trapped mosquitoes have tested positive for the West Nile virus this year. While there are no human cases reported in Kent County yet this year, these tests lead health experts at KCHD to believe that a rise in human cases is possible in 2018.

“Given the test results we are seeing, it may be more important now than ever to take steps to protect yourself and those who count on you from being bit,” said Adam London, Administrative Health Officer at KCHD. “We are urging people to take simple precautions to reduce their exposure to mosquitoes and the risk of West Nile virus.”

They reported that in the first 11 weeks of sampling this year, they collected 16,314 Culex mosquitoes, which are the ones that usually carry the virus. That’s about six times as many as last year. Of the eight pools of 50 tested, 26 percent had the virus.

London reportedly said he has never had West Nile surveillance data of more concern than this year’s.

There is no vaccine or cure for West Nile. The best treatment is prevention. KCHD recommends the following:

  • Applying insect repellant that contains the active DEET and always following the manufacturer’s directions for use on the label.
  • Draining standing water in the yard. Empty water form flowerpots, pet bowls, clogged rain gutters, buckets, barrels, and cans. Anywhere water can collect, mosquitoes can breed.
  • Avoid being outside at dusk and dawn when mosquito activity is high.
  • Wear light colored long-sleeved shirts and long pants.

West Nile virus is spread primarily by infected Culex mosquitoes. Only about 20 percent of the people infected will notice symptoms that may include headache, body aches, joint pains and fatigue. Most people with this type of West Nile virus completely recover, but fatigue may last for weeks. West Nile can develop into a severe illness that can affect the central nervous system. Some damage to the central nervous system can be permanent. In rare instances the disease can lead to death.
