Summary of prevalence data for community and school antibody (Bm14) positives in 2 PHI areas Unawatuna (Galle district), Weligama (Matara district) in southern province.

<p>Data shown are antibody prevalence (%, 95% CI) by age and gender. Antibody prevalence in school children within these two communities are shown for 6–8 age for comparison. Antibodies to recombinant filarial antigen Bm14 were much more frequent in adults than in school age children (ages 10–17), and antibody prevalence was much higher in adult males than in females. Significance test results (*<i>P</i> values) on antibody prevalence in males are shown for each age group above the bars.</p

Comparison of comprehensive filariasis surveillance data for Kalutara North (KA2), Ambalangoda (GL1), Unawatuna (GL2), Weligama (M2) and Borella (C4) and Peliyagodawatta (G3) sentinel sites in Sri Lanka.

<p>Data shown are prevalence for LF parameters in community and school children and prevalence of filarial DNA in mosquitoes (% with 95% confidence intervals). Significance results with <i>P*</i> values shown for KA2, and G3 are for differences in prevalence for these LF parameters between years in the same sites.</p

The map shows 8 filariasis endemic districts with approximate locations of 19 sentinel sites that were surveyed in 2011–2013 (blue and red circles).

<p>Six areas in red circles in 5 districts were reexamined in 2015–2017 for this study. The inset map shows surveyed sentinel sites in Colombo city and in the adjacent Colombo and Gampaha districts.</p

Percentages of mosquito trap locations in coastal PHM areas that yielded mosquito pools that were positive for filarial DNA by qPCR.

<p>Bars with the same color show results from PHMs within a single MOOH area. Twenty-two % of trap locations captured mosquitoes with filarial DNA, but some locations had much higher rates.</p

Distribution of mosquito trapping locations tested for filarial DNA in 60 PHM areas in Galle district.

<p>Molecular xenomonitoring results show trap locations with no mosquito pools positive for filarial DNA (coastal: green and inland: blue waypoints), and traps with one or more positive pools for filarial DNA are shown in red (in the coastal and inland EU areas).</p
