title: First Report of Human Fascioliasis in an Endemic Region of Bovine Fascioliasis in Caldas-Colombia.
abstract: Fascioliasis causes significant economic losses to the cattle industry and is considered a reemerging zoonosis. In Caldas-Colombia, an increase of bovine fascioliasis was detected at the Manizales Municipal Slaughterhouse, which is a potential risk to public health. The ecoepidemiology of human fascioliasis was analyzed in a region of bovine fascioliasis in Caldas-Colombia. The risk factors were studied. Samples were taken from 111 people who were directly related to the bovine milk production process. The immunoglobulin G frequency of Fasciola hepatica was determined in serum. A seriate stool test and a molecular analysis were conducted on those with positive results to look for parasite eggs and DNA, respectively. 6.3% of the samples were positive for the presence of antibodies; none was positive for the presence of eggs, while two samples showed a weak amplification band of the 124-bp DNA fragment of F. hepatica. Fifty-seven percent of the positive samples came from places located at 2026 meters above sea level (masl); 71% of people testing positive had been recently dewormed. Also, 86% had been in contact with cattle and handled grass and excrement. They eat salads and drink untreated water from the springs or ravines of the area. An outbreak of human fascioliasis was detected in Caldas, associated with risk factors for the disease. Clinical trials to confirm the presence of the parasite and implement public health control measures are required.
