The delivery to the Superintendência de Controle de Endemias (SUCEN) of an insect suspected of being the “barbeiro”, the transmitter of the Chagas’ disease, unleashed a focal point investigation with laboratory and field operations. The insect had been found in the house of the person who had brought it in; examination showed it to be the “barbeiro”, that is, P. megistus, infected with Trypanosoma cruzi. Investigation proved the enzootic presence of South American Trypanosomiasis in the area and the possibility of houses being invaded by the T. cruzi. This was avoided through controls put into effect immediately, showing the importance of promptly informing the health agency responsible and thorough follow-up by health authorities.
