Objective To studies the strategy and technical measures for interrupting the transmission of Bancroftian jUariasis. Methods Surveillance of Bancroftian filariasis in the epidemic area was performed. The effect of blood diagnosis and hetrazan(DEC) treatment was studied. The measurement of repeat surveillance of the sourses of infection was established and promoted. A surveillance system was formulated to eliminate the remaining sources of infection. Results Control strategies for treating the sources of infection were established. Investigation and treatment of raicrofilaremia was carried out repeatedly. The Bancroftian filariasis treatment of microfilaremia was carried out repeatedly. The Bancroftian JUariasis transmission had been interrupted and the Bancroftian filariasia had been eliminated in Baiyun district in 1998. This has been evaluated by the experts of Guangdong Provincial Public Health Bureau. Conclusion Bancroftian filariasis transmission could be interrupted and elimination could be achieved.
