Mosquitoes carrying the potentially paralyzing West Nile virus have been detected in at least seven states so far this summer — including New York.
Four of the seven states — Iowa, Illinois, Arkansas and Arizona — have seen West Nile virus cases in humans, according to the Centers for Disease Control and Prevention.
The Empire State’s infected mosquitoes were caught in late June in two Rockland County towns, Best Life reported, citing local officials.
“This is typically the time of the year we expect to see a rise in West Nile virus activity, and these positive mosquito pools confirm that,” Rockland County Health Commissioner Patricia Schnabel Ruppert said in a July 2 statement announcing the cases.
Massachusetts and Colorado are reportedly the other two states that have reported the disease-carrying mosquitoes, without identifying any human cases.
Colorado announced the discovery on Wednesday, the Denver ABC affiliate reported, and health officials there said the blood-sucking flies are more common this year in the state due to the steamy weather.
Severe cases of the West Nile virus can be debilitating to humans, according to the CDC, causing, among other symptoms, high fevers, tremors and even paralysis.
Anybody can experience a severe case, but people older than 60 are more vulnerable, the agency says.
