But this sharp increase “likely reflects changes in surveillance methods rather than change in disease risk,” according to the CDC.
The vast majority of Lyme disease cases in the US are reported from just over a dozen jurisdictions in the Northeast, mid-Atlantic and upper-Midwest where ticks are particularly prevalent.
Despite the significant spike, the number Lyme disease cases that are reported to the CDC is just a fraction of the estimated number of total cases.
There are about 476,000 estimated diagnoses of Lyme disease in the US each year – nearly eight times more than even the improved surveillance methods captured in 2022.
Lyme disease is the most common vector-borne disease in the US, along with Zika virus, West Nile virus, dengue, malaria, plague, Rocky Mountain spotted fever and alpha-gal syndrome.
