Results The overall incidence of scrub typhus in Anhui Province showed an upward trend from 2008 to 2017 ( χ2=3 522.49, P<0.001). The highest incidence rate in 2016 was 3.98/100 000. The cases were concentrated from September to November. It was a typical “autumn and winter type” and peaked in October. It had the phenomenon of “high incidence in October”; the cases were mainly concentrated in the age group of 40-79 years old, accounting for 76.64% of the total reported cases.
