In November 2013, a malaria outbreak of 11 cases occurred in Cusco, southern Peru, where falciparum malaria had not been reported since 1946. Although initial microscopic diagnosis reported only infection in each of the specimens, subsequent examination by the national reference laboratory confirmed infection in all samples. Molecular typing of four available isolates revealed identity as the B-variant (B) strain that was responsible for a malaria outbreak in Tumbes, northern Peru, between 2010 and 2012. The B strain is multidrug resistant, can escape detection by PfHRP2-based rapid diagnostic tests, and has contributed to two malaria outbreaks in Peru. This investigation highlights the importance of accurate species diagnosis given the potential for . to be reintroduced to regions where it may have been absent. Similar molecular epidemiological investigations can track the probable source(s) of outbreak parasite strains for malaria surveillance and control purposes.
