Accepted Answer

Lyme disease, transmitted by the bite of infected ticks, is the most common vector-borne disease in the United States. In 2018, there were over 33,000 reported cases of Lyme disease in the country. In comparison, malaria, which is also a vector-borne disease, is relatively rare in the United States with fewer than 2,000 cases reported annually, most of which are imported from other countries. Influenza A and pneumonia are not vector-borne diseases.
