A case of human infection with a novel Babesia species in China.

ABSTRACT:

Background

Babesiosis is an uncommon but emerging tick-borne disease caused by the genus Babesia. In this case study, we report a case of human infection with a novel Babesia sp. in China.

Findings

The patient in question had been suffering from repetitive occurrences of mild fever of unknown origin and fatigue for 10 years.
