Which disease is the most reported vector-borne disease in the U.S.?

Lyme disease is recognized as the most reported vector-borne disease in the U.S. It is primarily transmitted to humans through the bite of infected black-legged ticks, also known as deer ticks, which are prevalent in many areas of the country. The disease has seen a marked increase in reported cases over the decades, particularly in the northeastern, north-central, and Pacific coastal regions, due to factors such as changes in land use, increased deer populations, and increased outdoor activities among the population.

The monitoring of Lyme disease cases facilitates better understanding and management of its spread, contributing to public health efforts aimed at controlling tick populations and educating the public about preventive measures. This makes Lyme disease not only the most reported vector-borne disease in the U.S. but also a significant public health concern. The other diseases listed may also have notable impacts, but none have reached the same level of reporting prevalence as Lyme disease in the current context.
