The history of the elimination of lymphatic filariasis in China.

China used to be one of the most heavily endemic countries for lymphatic filariasis (LF) in the world. There were 864 endemic counties/cities in 16 provinces/autonomous regions/municipalities (P/A/M) with a total population of 330 million at risk of infection. Since the founding of the People's Republic of China in 1949, the Chinese Government has designated the control of the disease to be a top priority. Due to decades of sustained efforts, close cooperation related to LF control among government departments, and active participation of endemic populations, an all-round campaign for prevention and control has been carried out vigorously and successfully. Over many years, great achievements have been made through persistent endeavors of Chinese scientists and disease control workers. The ultimate goal to eliminate LF in the country was achieved in 2006.
