Objective:
To summarize the technical measures in achieving the elimination of lymphatic filariasis in Tengzhou city.
Methods:
To collect and analyze the materials on research and control of lymphatic filariasis in Tengzhou city during the disease elimination program over the 40 years.
Results:
Following to the national criteria for the control and elimination of filariasis, efforts were made for epidemiological investigation, mass blood examination, and mass drug administration by taking diethylcarbamazine (DEC) medicated salt for the whole population. After the criteria of transmission interruption (basic elimination) of filariasis were met in 1974, re-examination and treatment for the cases with microfilaremia, and parasitological and entomological surveillance were conducted. In 1995, filariasis elimination in the whole city was declared.
Conclusion:
Comprehensive measures focusing on the elimination of source of infection were proved effective for interrupting the transmission of filariasis. Unremitting surveillance was necessary for achieving the goal of elimination of filariasis.
