[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.
