MONSALVE-CASTILLO, Francisca Mercedes et al. Prevalence of infectious agents in indigenous women of childbearing age in Venezuela. Biomédica [online]. 2012, vol.32, n.4, pp.519-526. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.v32i4.749.

Introduction. The ToRCH syndrome includes the following infectious pathogens: Toxoplasma gondii, rubella, cytomegalovirus and herpes simplex virus 1 and 2. In susceptible pregnant women, these pathogens can cause abortions and congenital malformation in the newborn babies. Objective. The seroprevalence of infection by ToRCH agents was determined in women of childbearing age in several Venezuelan Yukpa indigenous communities. Material and methods. In 2007, 109 samples were selected from 151 women with an age range of 14 to 40 years old. The determination of antibodies against ToRCH agents was carried out through the indirect enzyme immunoassay technique by ELISA´s technique of Smartest Diagnostics. Results. Of the 109 samples, 85.5% presented antibodies against T. gondii, 95.4% for rubella, 75.2% for cytomegalovirus and 97.2% for and herpes simplex virus 1 and 2. A relationship between abortion and infection by cytomegalovirus and herpes simplex virus 1and 2 was noted in 21.1% and 30.2% of women presented, respectively. Conclusions. The findings show a high prevalence of ToRCH agents in women in childbearing age in Yukpa indigenous communities in Venezuela. Poor sanitary conditions and consumption of water contaminated with oocysts may be an important way of transmission of T. gondii. Overcrowding in the communities, sexual activity at an early age and number of partners and may be related to the presence of cytomegalovirus and herpes simplex virus HSV-1 and 2.
