West Nile Cases Reach 31 in NYC As Season Continues
New York
Published · Updated
Summary
- New York City's West Nile virus count has climbed to 30 confirmed human cases citywide, up from 16 three days ago. Twenty-four cases are the more severe neuroinvasive form of the disease, while the remaining six are West Nile fever.
- New Yorkers 65 and older are three times more likely than younger adults to develop severe illness. People with weakened immune systems are also at higher risk. Most people who are infected have no symptoms. Some develop a mild illness with fever, headache, body aches, joint pain, vomiting, diarrhea, or rash. A small number develop serious neurological illness, including meningitis or encephalitis. Anyone in a higher-risk group who develops fever with a severe headache, confusion, or neck stiffness should seek care promptly.
- Mosquitoes carrying the virus remain active into October. The Health Department continues to spray for adult mosquitoes in neighborhoods with elevated activity.
- Here's how you can stay safe:
- Use an EPA-registered insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus (not for children under 3).
- Wear long-sleeved shirts, long pants, socks, and shoes when spending time outdoors in areas with mosquito activity.
- Limit outdoor activities during dawn and dusk, when mosquitoes are most active.
- Install and repair window and door screens to keep mosquitoes out.
- Empty standing water at least once a week from buckets, flowerpots, birdbaths, and other containers. - Report chronic standing water to 311.
- Maintain swimming pools, hot tubs, and ornamental ponds by keeping them clean, chlorinated, covered, or drained when not in use.
