Deadly Yet Easily Treatable
In the outbreak of 119 confirmed and suspected cases in Venezuela, 20.3% required hospitalization, and a 5-year-old child died of acute myocarditis. These percentages differ from those reported in vector transmission, which is asymptomatic in the acute phase for 95%-99% of cases or will only develop a mild febrile illness that resolves on its own.
“Not all cases will present as severe, because depending on the inoculum, there may be individuals with subclinical situations. But any food poisoning that occurs in endemic areas, where food is not properly controlled, and these street foods are associated with processes in jungle areas, raises the possibility that T cruzi is involved and should be considered as a differential diagnosis,» noted Dr. Chuit. “The treatment is highly effective, and people recover quickly.”
“The most important thing about oral transmission of Chagas is that someone infected in this way needs antiparasitic drugs immediately. We can cure them if we treat them immediately,” said Dr. Beatty, adding that treatment is sometimes delayed due to lack of access to appropriate antiparasitic drugs. “Here in the United States and in Latin America, it is quite common for healthcare professionals not to understand the differences between vector, vertical, and oral transmission. By not treating these patients, they become ill quickly.”
Dr. Beatty and Dr. Chuit declared no relevant financial conflicts of interest.
