Cyclospora Outbreak
As of July 2026, New York is part of a multistate outbreak of cyclosporiasis. New York has reported approximately 394 cases since May 1st. Health officials have not identified a single contaminated food source. Cyclospora is a microscopic (tiny, not seen without a microscope) parasite that can affect the intestinal tract and cause diarrhea (loose stool) in those who get infected. People get infected when they eat or drink food or water contaminated with the parasite. Learn more about Cyclospora.
Heat and Sun Safety
When high humidity and temperatures are forecast, the Health Department recommends that residents avoid strenuous activity, drink lots of water, avoid alcohol and caffeine, and take precautions to prevent heat-related illness. If you need a place to go to beat the heat, you can find a cooling center near you by using the NYSDOH Cooling Center Finder. High heat and humidity can also lead to unhealthy ozone levels. The New York State Department of Environmental Conservation forecasts daily ozone conditions on its web site for the New York Metropolitan area, which includes Westchester County.
Protect Against Tick Bites and Prevent Disease
Ticks can carry and transmit a range of diseases that pose risks to our health, most commonly Lyme disease, which is spread by infected blacklegged (deer) ticks. Ticks are normally found in wooded, brushy, and grassy areas, making it more likely you’ll be exposed when spending time outdoors. In addition to Lyme disease, ticks in New York may also transmit other illnesses such as anaplasmosis, babesiosis, ehrlichiosis, and Powassan virus disease. Tick bites are often painless and ticks can be very small, so you may be unaware that you have been bitten. Recognizing tick habitats, understanding how tick-borne diseases are spread, and taking preventive measures—such as using insect repellent, wearing light colored long sleeves and pants, and performing thorough tick checks—are key to reducing your risk of tick-borne diseases.
New York State Department of Health Confirms That Childhood Vaccination Policies Remain Unchanged
The New York State Department of Health has confirmed that New York State's existing childhood vaccination policies, including school immunization requirements, remain unchanged at this time following a recent federal announcement revising routine childhood immunization recommendations. There is no change to vaccine access, insurance coverage, liability protections or the federal Vaccines for Children (VFC) program, which continues to provide vaccines at no cost to eligible children. Learn more about childhood vaccines.
Avian Influenza (Bird Flu)
Highly Pathogenic Avian Influenza (HPAI) continues to infect birds and mammals across the U.S. and Canada, including New York State. With wild bird mortalities from HPAI increasing in late fall and peaking over the winter months, the New York State Department of Environmental Conservation (DEC) reminds New Yorkers to stay alert. Learn how to protect yourself, your family and pets from Avian Influenza.
