Le résumé fourni par la source

Plasmodium falciparum infection threatens military populations deployed to highly malaria-endemic regions, such as Peruvian Army peacekeepers deployed to Central African Republic. During deployment, malaria cases were identified by microscopy and rapid diagnostic tests. After deployment, we performed malaria diagnosis by malachite green loop-mediated isothermal amplification and photo-induced electron transfer PCR assays. We used ELISA to test for P. falciparum C-terminal 19-kDa region merozoite surface protein 1-specific IgG from 97 peacekeepers. Malaria prevalence during deployment was 33.33% and we detected 4 cases after deployment: P. falciparum (n = 2), P. ovale (n = 1), and Plasmodium spp. (n = 1). IgG surveillance showed a seroprevalence of 31.96% in peacekeepers, who had a high P. falciparum exposure during deployment. Our findings reinforce the necessity of active surveillance in military populations to reduce the risk for introduction of new Plasmodium species and strains into the Americas from malaria-endemic areas.
