There were 2 million people infected either by B. malayi or W. bancrofti that 1.6 million microfilaremia cases and 0.4 million chronic patients. The average rate of microfilaremia among population was 5.94%. Anopheles sinensis and Culex quinquefasciatus were the principal transmitting vectors. Since 1970s,with the strategy of taking elimination of infection source as a major focus,the average rate of the microfilaremia reduced to 0.048% with a village as the unit in 1988,and reached the standard of transmission interruption. With continuous surveillence for over a decade,the province reached the goal of filariasis elimination in 2001.
