The following is from Westchester County:
The Westchester County Health Department announced that this season’s first batch of mosquitoes carrying West Nile Virus in Westchester was identified in Mamaroneck. The area surrounding the positive mosquito batches was inspected today by the Health Department, which has treated nearby catch basins to protect against further mosquito breeding nearby.
Westchester County Executive George Latimer recommended residents follow the Health Department’s West Nile Virus prevention advice to avoid mosquito bites.
“We can keep mosquitoes from breeding and biting us in our own backyards if we pour out standing water after it rains and remove or turn over wheelbarrows, flower pot drip trays and any toy pails or watering cans," Latimer said.
To date, this is the first positive out of 195 batches of mosquitoes collected in Westchester that were tested for West Nile Virus by the New York State Department of Health. Last year, the first positive batch was collected in Westchester on July 24. Statewide, the state Health Department had identified 361 positive mosquito batches as of August 30, including 266 in New York City.
“To protect yourself and your family when you spend time outdoors, use repellents, especially from dawn to dusk, when mosquitoes are most active,” Sherlita Amler, MD, Commissioner of Health, said.
The Health Department gave 450 pounds of free fathead minnows to residents with ponds to reduce the mosquito population. The minnows reduce the mosquito population by feeding on larvae and pupae before they emerge into adult mosquitoes.
Throughout the season, the Department also traps and tests mosquitoes to track the presence of mosquito-borne viruses in the County. Last year, West Nile Virus was identified in 10 local mosquito batches out of 393 submitted for testing and four people were diagnosed with West Nile Virus. In 2017, West Nile Virus was identified in five local mosquito batches out of 380 submitted for testing and three people were diagnosed with West Nile Virus.
West Nile Virus infection most often causes a mild or moderate flu-like illness, but can be more serious particularly for people 60 and older, and those with other health complications. Four residents were diagnosed with West Nile Virus in 2018 and three in 2017, and all recovered.
To reduce the chances for mosquitoes to breed and bite around your home, follow these tips:
- Avoid the outdoors in the late afternoon and early evening when mosquitoes are active and feeding; use insect repellents when outdoors during these times and follow the label instructions.
- To protect infants over two months of age, adults can apply insect repellents with up to 30 percent DEET to their own hands and then rub it onto their children. Products containing DEET are not recommended for use on children under two months of age.
- Wear long pants, long-sleeved shirts and socks when outdoors, especially in areas where mosquitoes are active and feeding.
- Discard or turn over cans, plastic containers and ceramic pots outside your home to avoid accumulating water.
- Remove standing water from outdoor toys and play houses.
- Remove discarded tires.
- Drill holes in the bottoms of all recycling containers that are left outdoors.
- Turn over plastic wading pools, buckets and wheelbarrows when not in use.
- Change the water in birdbaths at least twice weekly.
- Keep storm drains and gutters clear of leaves and debris.
- Chlorinate swimming pools, outdoor spas and hot tubs until properly winterized or drained for the season. Also, if not chlorinated, drain any water that collects on their covers.
Residents who notice large areas of standing water on public property should report them to the Westchester County Department of Health at (914) 813-5000.
