Epidemiological, temporal, and geographic trends of leptospirosis in the United States, 2014-2020.

ABSTRACT:

Background

Leptospirosis, caused by pathogenic Leptospira spp., is one of the most widespread zoonotic diseases globally. In 2014, leptospirosis was reinstated as a nationally notifiable condition due to evidence of increasing incidence and public health importance. We describe the epidemiological, temporal, and geographic trends of leptospirosis in the United States since reinstatement.

Methodology

Analysis included confirmed and probable leptospirosis cases from jurisdictions reporting ≥ 1 case between 2014-2020. Analyzed data included reportable case surveillance and voluntarily submitted supplemental data.

Principal findings

Between 2014-2020, CDC received 1,053 case reports from 34 jurisdictions. The national incidence rate was 0.48 cases per 100,000 population.
