Surveillance of filariasis in some vulnerable areas in Guangxi after filariasis elimination

Objective] To explore the measures for continuing surveillance of filariasis. [Methods] Selecting some vulnerable spots for focal surveillance, double\|slide biood sampling for microfilaria examination, dissecting vectors for detecting the mosquitoes infected with filarial larva, using IFAT for detecting antifilarial antibody. [Results] 27 938 persons were examined for microfilaria and 4 454 mosquitoes were dissected for filaria larva, all were negative. 3 606 serum samples were examined for antifilarial antibody average positive rate was 1 35%(0 39%～4 97%). [Conclusion] The results of surveillance showed that the achievement of filariasis control in Guangxi after filariasis elimination is consolidated.
