Health problems associated with international travel: A case of cutaneous myiasis in China due to Cordylobia anthropophaga imported from Uganda.

More affordable international travel, global trade and commerce, and the exporting of labor have all contributed to international population mobility. Furthermore, population migration leads to the incidence or recurrence of once-controlled diseases. Evidence shows that the popularity of travel can impact health through imported infections and illness. Imported cutaneous myiasis, a type of skin lesion, has attracted the attention of the current authors. This condition often occurs among travelers and it has been reported in several non-endemic countries. However, diagnosis of myiasis and identification of the larvae are difficult. Advances in molecular detection techniques could provide a new way to identify larvae. This study used sequencing of the 28S rRNA gene and morphology to identify the larva infesting the upper arm of a Chinese woman returning from Uganda. The larva was identified as Cordylobia anthropophaga (C. anthropophaga) and the sequences were submitted to GenBank (accession number: KM506761). As foreign interaction increases, imported health problems may become more common in China. Knowledge about various pathogens needs to be increased and molecular methods need to be used to accurately identify those pathogens.
