It has been well known that leptospiroisis is a one of the prevailing acute febrile diseases in Korea.
In order to find out the incidence of past infection of L. interrogans among normal population, a total of 1,171 sera obtained from rural residents and tested by microscopic agglutination test. All of normal resident's sera were collected during July in 1987, just before epidemic season, at Keochang county(248 sera), at Wanju county(145 sera), at Wonseoung county(255 sera), at Cholwon county(411 sera) and at Kongju county(112 sera).
Seropositive rate against L. interrogans among rural residents was 12.0% and ranged from 2.7% in Kongju county to 18.5% in Cholwon county. There was a higher
seropositive rate in males and the majority of seropositives occurred in the age group over 30 yesrs. Icterohaemorrhagiae was a most commonly reacting serotype of L. interrogans and followed by CH-48 and Canicola. The sera reacted with Cynopteri, Ballum, Australis, and Pyrogenes were present also.
