Molecular screening of Plasmodium infections among migrant workers in Thailand
Background & objective: A cross-sectional study was conducted to determine the prevalence of Plasmodiuminfections among migrant workers in Thailand.Methods: A total of 241 migrants at Kanchanaburi, Pathumthani and Nakornpathom provinces of Thailand wererecruited in our surveillance. Blood sample...

Blood samples were examined for human malaria parasites by using microscopyand semi-nested multiplex PCR (SnM-PCR).Results: Laboratory diagnosis revealed 6.2% total positive rate. As compared to microscopy (26.7%), SnM-PCRwas more sensitive (93.3%) for malaria. Plasmodium falciparum was predominant than P. vivax (53% : 40%,respectively). The majority of positive cases were from Myanmar workers who had low parasitaemia and withoutsymptoms.
