[Seropositivity of HIV, HBV, HCV and Treponema pallidum in blood donors in southeast Mexico].
OBJECTIVE
To determine the prevalence of serological markers for the human immunodeficiency virus (HIV), hepatitis B (HVB) and C (HCV) viruses, and Treponema pallidum in blood donors.


METHODS
The results of the screening tests from blood donors studied at the Central Blood Bank of the Ignacio Garcia Tellez National Medical Center, in Merida, Yucatan, Mexico between January 2002 and December 2004, have been retrospectively evaluated.


RESULTS
Of 39,933 blood donors, 424 (1.06%) were positive to one or more serological markers. The seropositivity rates for anti-HIV, HBsAg, anti-HCV and anti-Treponema pallidum were found as 0.13%, 0.20%, 0.44% and 0.29%, respectively. Western Blot positive was found in 41 (77.36%) of the 53 blood donors positive for anti-HIV.


CONCLUSIONS
In this study, the prevalence of serological markers was similar or lower than that reported in previous studies in Mexico.
