[Epidemic and research progress of babesiosis].

Babesiosis is an emerging parasitic disease, distributed globally in Europe, Asia, Africa, North and South America, and Australia, and the United States is still the country with the largest number of babesiosis cases reported. Babesiosis in China is mainly distributed in the northeast, followed by the southwest and other regions. As a new vector-borne infectious disease, babesiosis poses a serious threat to human health, and its research foundation is relatively weak, so it requires more attention and recognition. The research hot spots on babesiosis are screening of diagnostic antigens, and the mechanisms of Babesia and the hosts, co-infections between Babesia and other pathogens. The epidemic distribution, screening of diagnostic antigens, host immune response mechanism and co-infection of babesiosis in our country and abroad are reviewed in this paper.
