Anne Arundel County Department of Health announced that mosquitoes trapped in two parts of their county on July 11, 2023, have tested positive for West Nile Virus (WNV). These are the first WNV positive mosquitoes identified in Anne Arundel County this year.
At this time, no human cases have been reported in Anne Arundel County. In addition to Anne Arundel County, mosquitoes trapped in Bowie, Prince George’s County, have also tested positive for WNV.
WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.
Most people exposed to the virus don’t get sick, but about 20 percent develop symptoms like headache, fever, muscle and joint aches, nausea, and fatigue. The current warm weather, rain fall, and high humidity provides ideal conditions for mosquito activity and WNV transmission.
- To reduce the risk of being bitten by mosquitoes, residents should: TIP IT OR TOSS IT!! Remove standing water. Emptying out water that collects in toys, tires, trash cans, buckets, clogged rain gutters and plant pots will prevent mosquitoes a place to lay their eggs and reproduce.
- Keep all swimming pools chlorinated and filtered. Backyard ponds should include fish to control mosquito larvae.
- Minimize time spent outdoors between dusk and dawn when mosquitoes are most active.
- Be sure door and window screens are tight-fitting and in good repair.
- Wear long sleeves and pants. Create a barrier to mosquito bites by covering up.
- Consider using EPA-registered repellent such as those containing DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone.
- Use mosquito netting when sleeping outdoors or in an unscreened structure and to protect infants when outdoors.
