Toxoplasma gondii seroprevalence in a university hospital in Chile

Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii. It is estimated to affect a third of the world's population. In Chile, in 1996, a seroprevalence of IgG antibodies against T. gondii of 36.9% was reported, which progressively increased from north to south of the country. There are no updated reports of the seroprevalence of T. gondii in the Metropolitan Region. In the present study, we determined the seroprevalence of anti T. gondii IgG in the 2013-2018 period at the Clinical Hospital University of Chile. Of a total of 1,666 results, 386 (23.2%) were positive, without gender differences, but with a significant increase with age. A decrease in seroprevalence was not observed in the last six years, however the results obtained show a significant reduction compared to previous research carried out in the Metropolitan Region.
