Epidemiological status of kissing-bugs in South East Asia: A preliminary assessment

Abstract:

tKissing-bugs (Triatominae) are being increasingly reported as a biting nuisance in SE Asia, with severe bite reactions sometimes leading to anaphylactic shock. In addition, they pose a risk for vector-borne transmission of trypanosomiasis, with potential diagnostic difficulties due to the range of trypanosome species in the region. Here, we review available information about Triatominae in Asia, and present additional comparisons using morphometry, cytogenetics, and new DNA sequence data, to clarify the irrelationship with each other and with the better known American species. We deduce that all Asian Triatominae have probably derived from forms originally spread during the 15-18th centuries on sailing ships, from the area that now forms the southern USA.
