Community risk of environmental-borne cystic echinococcosis transmission in South America: Results from the multistep cross-sectional and case-control PERITAS study.

ABSTRACT:

Background

Cystic echinococcosis (CE) is mainly described as a food/waterborne zoonosis. However, evidence about matrices contamination is scarce. Identifying main transmission routes could optimize health messages aiming to prevent ingestion of parasite eggs. We evaluated Echinococcus granulosus contamination of matrices in two areas of Chile and Peru.

Methodology/principal findings

In stage 1, areas with high active CE prevalence were identified through cross-sectional ultrasound surveys. Stage 2 was a case-control study encompassing matrices sampling in public places and households with and without CE cases in these areas, followed by (stage 3), matrices processing by sequential sieving and E. granulosus detection by PCR.
