RECOUNT OF REPORTED CASES OF HUMAN FASCIOLIASIS IN BRAZIL OVER THE LAST 60 YEARS
Palavras-chave:Trematode, parasites, Fasciola spp., public health, zoonosis.
ResumoFascioliasis is an important anthropozoonotic disease caused by the ubiquitous trematode helminth, Fasciola spp. Here, as elsewhere, it is thought that the disease lacks proper reporting, and the available literature does not reflect unreported cases found in the Brazilian population, or new recently reported cases. The purpose of this work was to perform a recount of human fascioliasis (HF) cases in Brazil. For this, we considered all positive cases published in local and international official Journals, from 1950 to 2016. A theoretical-conceptual research method based on a systematic bibliographic review was applied to identify, select and index articles using the Endnote Basic Software. Here, only 48 cases of HF were found, of which 21 (43.7%) occurred in the South of the country. The small number of reported cases reflects the difficulty in diagnosing HF correctly (clinical and fecal tests). This work provides a real figure of HF reported cases in Brazil and has also corrected inaccurate information found in the literature by conducting a historical survey of the disease. Fasciola hepatica is highly endemic in ruminants and, hypothetically, the number of human cases should also be considerably higher than that reported in the literature. These findings call for more attention in regard to this neglected disease in Brazil.
