[The type of leptospirosis epidemic and serogroup transformation in Fujian province in recent years].

By analysis of investigations in recent years in Fujian province, it was found that the main type of leptospirosis epidemic was rice-field type, the other was flood type which had the tendency to shift from coastal plain area to northwest area. In the main epidemic area, Wupin county, the detection rate of Hebdomadis serogroup rate sharply declined (P < 0.01), however, that of Batavia serogroup markedly increased (P < 0.01).
