NEW YORK (1010 WINS) — The number of West Nile Virus cases and positive mosquito pools have surged in New York City this year, according to city health data.
There have been 20 West Nile Virus cases documented across the city so far this year — up from just 7 documented cases in 2020 and 10 cases in 2019. Though the figure is still down from the 36 West Nile cases reported in 2018, the data shows.
At the same time, the number of positive West Nile Virus mosquito pools have also significantly increased in the city.
The Department of Health identified a record-high 1,117 positive mosquito pools, or groups of mosquitos trapped and tested together, compared to just 446 pools found last year and 406 discovered in 2018.
Even with the higher number of West Nile cases in 2018, the city still discovered fewer pools that year, documenting 1,024 groups of positive insects.
Health officials found the highest number of positive pools in Queens and Staten Island, with 392 clusters and 320 clusters identified, respectively. The latest positive mosquitos were found in Long Island City and Middle Village in Queens, and in New Dorp on Staten Island, according to the health department.
Peak West Nile virus transmission usually lasts between June to October, the agency said. It’s pointed to the heavy amounts of rainfall this summer weather as a possible contributing factor to 2021’s uptick.
“While the end of summer is around the corner, we want all New Yorkers to be aware that mosquitoes are still active,” DOH Commissioner David Choshki tweeted in September. “When outdoors, wear insect repellent and remove standing water from your property. If you observe standing water not on your property, please report it to @NYC311.”
Typical symptoms of West Nile Virus include fever, muscle aches, and extreme fatigue. Many of those infected are unaware of the virus.
