An epidemiologic field study was conducted in the village of Borbòn in Esmeraldas province in northern Ecuador to compare different parasitologic methods in the diagnosis of infection with the Entamoeba histolytica/Entamoeba dispar complex. The results of two stool antigen detection assays (the Prospect Entamoeba histolytica microplate assay and the E.(More)
Chagas disease, a neglected tropical disease that due to population movements is no longer limited to Latin America, threatens a wide spectrum of people(travellers, migrants, blood or organ recipients,newborns, adoptees) also in non-endemic countries where it is generally underdiagnosed. In Italy, the available epidemiological data about Chagas disease have(More)
Onchocerciasis is a major blinding disease in equatorial Africa and Central and South America. Ivermectin is a safe and effective drug in the treatment of this disease and now forms the basis of disease control in most endemic areas. We report the findings of long-term control of this infection in the Río Santiago focus in Ecuador, between January 1990 and(More)
Cardiovascular diseases are widespread in developing countries, but little is known about cardiovascular risk profiles in rural communities. To assess the importance of arterial hypertension in a rural district of Ecuador, we screened 4284 of the 8876 adults who lived in the area. 1542 (36%) individuals had hypertension, only four (0.3%) of whom were well(More)
BACKGROUND Seventy percent of imported malaria cases in Italy occur in immigrants, generally with milder clinical presentation due to premunition acquired through repeated infections. Nevertheless, premunition could be progressively lost after a long period of nonexposure. We investigated the changing pattern of malaria in immigrants in two definite 5-year(More)
BACKGROUND Since the year 2000, in Italy, there has been a constant decrease in the number of cases of imported malaria in immigrants. Nevertheless, immigrants still account for about 70% of reported cases. To our knowledge, no data are yet available on imported malaria in children. This paper describes the main characteristics of malaria cases observed in(More)
Strongyloidiasis remains an underestimated public health problem, just as it was at the dawn of last century. In 1901, Professor William Sydney Thayer published a review, ''On the Occurrence of Strongyloides intestinalis in the United States,'' concluding: ''…one may be justified in emphasizing the following points: 1. ''Diarrhoea associated with the(More)
Yaws is no longer a national and international health priority for intervention, but there is still a negative perception of the disease in the few affected communities. A survey in 1988 in the northern region of Ecuador documented a prevalence of 16.5% of clinical cases and 96.3% of serological cases. A continuous, long-term community-based surveillance(More)
