The migration of invasive vector species has contributed to the worldwide extension of infectious diseases such as dengue (
Aedes aegypti
) and chikungunya (
Aedes albopictus
). It is probably a similar behaviour for certain vectors of Chagas disease which allowed it to become a continental burden in Latin America. One of them,
Triatoma rubrofasciata
has also been spreading throughout the tropical and subtropical world. Here, the recent and massive peridomestic presence of
T. rubrofasciata in Vietnam cities is reported, and tentatively explained, highlighting the need for improved entomological surveillance.
