According to new data, the number of tick bites and tick-borne illnesses is expected to rise significantly in Upstate New York in 2026. Experts say the region is seeing an increase in tick populations and the prevalence of ticks carrying multiple diseases.

Why it matters

Tick-borne diseases like Lyme, anaplasmosis, and babesiosis can have serious health consequences if not treated properly. The potential for more widespread tick activity and disease transmission poses a growing public health concern for Upstate New Yorkers.

The details

The data shows that tick populations and the rates of tick-borne illnesses have been steadily increasing in recent years across Upstate New York. Experts attribute this trend to factors like milder winters, increased deer populations, and the expansion of tick habitats into suburban and urban areas.

  • In 2021, the New York State Department of Health reported a 20% increase in tick-borne disease cases compared to the previous year.
  • Tick activity typically peaks in the spring and summer months in the region.
