STUDY OF RISK FACTORS FOR TOXOPLASMOSIS AND SEROPREVALENCE IN STUDENTS OF THE CAREER OF BIOCHEMISTRY U.S.F.X.CH.

Abstract

Toxoplasmosis studies in Bolivia have been carried out in pregnant women who come to their prenatal controls and few refer to risk factors for the disease. Thus, the objective of the present investigation was to establish the risk factors and seroprevalence for toxoplasmosis in a heterogeneous population: men and women of the Biochemistry degree of the San Francisco Xavier University of Chuquisaca carrying out a prevalence study with a quantitative approach, of observational, retrospective and analytical design.

We worked with a sample of 290 students of the Biochemistry career in which immunoserological techniques were developed: HAI as a discard technique and ELISA IgG and IgM for confirmation. 20.7% of seroprevalence were reported for toxoplasmosis with a predominance of IgG (96.7%) and in the case of IgM it was positive for a pregnant woman and for a male. The most predisposing risk factors for infection were: consumption of well or river water (OR = 38 and Chi square of 50.21), direct contact with land (OR = 33.29 and Chi square of 119.97), consumption of raw or semi-raw meat (OR = 5.74 and Chi square 11.91). Followed by living with cats and weather factor. All statistical analysis had an CI: 95.0%.

The decrease in seroprevalence in relation to other studies may be due to changes in environmental factors: decrease in consumption of raw or undercooked meat since the Influenza AH1N1 pandemic, greater coverage of provision of drinking water in rural and urban areas from management 2009
