The RLDT was highly specific, as all the culture positives were positive by RLDT, except 1 (sensitivity of 99%), and could detect all the PCR positives except 2 (sensitivity of 97%). Almost perfect agreement was found between RLDT and PCR (kappa 0.9). Rapid LAMP-based Diagnostic Test being more sensitive than culture and RDT, the agreement was moderate (kappa 0.6 and 0.5, respectively). Rapid Diagnostic Test missed detection of cholera in 11 samples, positive by other tests. The accuracy of RLDT was 100% in detecting cholera from water samples.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Rapid LAMP-based Diagnostic Test was specific and sensitive, detecting 21% more cholera-positive cases than culture or RDT.
