TAS was not sensitive for detecting low-level persistence of filariasis in Sri Lanka. The AFC also conducted school-based surveys for filarial antigenemia in according to WHO guidelines active at that time. By these criteria, Sri Lanka has achieved several WHO targets and the country is on track to achieve elimination. September 19, ; Published: A pilot study was performed in Peliyagodawatta in Gampaha district in as a training exercise and to test the feasibility of comprehensive LF surveillance in Sri Lanka using methods pioneered in Egypt.

Only three of children with positive antibody tests out of children tested for antibody from all 19 PHI areas had positive CFA tests, and all three of these children were Mf negative. These methods are complementary to TAS, and they are feasible for use by some national filariasis elimination programs. Discover Featured Music Videos People.

Transmission assessment survey results More than 17, primary grade school children were tested in TAS in schools located in 11 EUs in 8 districts and in Colombo town Table 5. Also, additional work is needed to develop and validate sampling methods for assessment of mosquito DNA rates in areas larger than PHIs.
A generalized linear mixed model was used to estimate design effects of household-based cluster sampling used in community surveys. Mosquitoes were collected with gravid traps Model , John W. Trap sites with no mosquito pools positive for filarial DNA are shown in blue, and traps with one or more positive mosquito pools are shown in red. Although vector control can be difficult to implement at the scale needed for LF elimination, surveillance results may identify hot spot areas where focused vector control may be feasible. A second problem with TAS is that filarial antigenemia rates in young children are sometimes very low in areas with ongoing LF transmission. The correlation between human and mosquito infection parameters was analyzed by the Spearman rank test.
