First evidence of human borreliosis local transmission in Cambodia

We report the first cases of confirmed human local transmission of borreliosis in Cambodia. Four patients, including cases with no travel history, presented typical clinical signs and tested positive for Borrelia burgdorferi antibodies. These findings confirm the presence, circulation, and local transmission of Borrelia in Cambodia. These results are important to convince for the need and the development of surveillance of tick-borne diseases in Southeast Asia.
