Project summary

Validation of a new rapid test for cholera compared to standard culture and PCR.

Lay summary

This study will compare the results of a new dipstick test for cholera that detects only Vibrio cholerae serogroup O1 (but not serogroup O139) with the results of standard stool culture and PCR using stool specimens collected on filter paper.

Potential for public health impact or global health decision-making

Validation of a new dipstick rapid test will allow for more rapid detection of cases and potentially will allow for more rapid declaring of an outbreak.
