Abstract:
Objective To analyse the effects of Word Bank Loan Schistosomiasis Control Project in Hunan Province from 1992 to 2000. Methods The administrative villages in Hunan endemic areas were divided into heavy, moderate and low zones respectively, based on human infection rates. Control strategies including a major approach of chemotherapy to inhabitants and bovines with praziquantel, complemented with health education as well as snail control by environment modification, were adopted in each endemic zone. Schistosomiasis prevalence surveillance was carried out in 50 moving pilots selected from endemic villages in each zone every year. Results At the beginning of the programm, there were total of 35 endemic counties (cities, districts, farms) and 471 endemic towns in Hunan Province. Up to 2000, 8 endemic counties (farms) reach the transmission interruption criteria, and 25 counties and 300 towns reach the transmission control criteria. Heavy endemic villages decreased from 762 to 271, while moderate endemic villages from 1728 to 1053, and low endemic villages increased from 1447 to 2716. Human infection rates dropped from 11.59% to 5.64%. Conclusion The schistosomiasis epidemic situation decreased obviously after implementing the project in Hunan Province.
