Objective: To assess the prevalence of mumps antibodies in children and adolescents of Mexico, two years after the introduction of the mumps-containing vaccine MMR.
Materials And Methods: Evaluation of IgG antibodies with a commercial kit of indirect ELISA.
Results: 2 111 children (1-9 years) and 2484 adolescents (10-19 years) were studied.
HPV is the sexually transmitted agent most common among young people, like college students. The aim of study was to associate sexual behavior characteristics of women with HPV, detected in genital samples taken before the introduction of the HPV vaccine. Female students during 2001-2005 donated genital samples and the samples were re-analyzed in 2013 for HPV genotyping by RT-PCR.

The aims of the study were to determine the HSV-2 seroprevalence and to evaluate the risk factors for HSV-2 in a national representative survey among adolescents and adults in Mexico.
Methods: A cross-sectional study was carried out in Mexico on the basis of the National Health and Nutrition Survey 2012, a national representative survey.
Objective: To identify the population group in which syphilis increase was concentrated.
Materials And Methods: The information was collected from the Mexico health statistical yearbooks. The information disaggregated by sex, age group and state during the period 2003 to 2013 was used to form different databases.
Article Synopsis
- - The study aimed to identify how common HPV is among male college students and explore risky sexual behaviors linked to the virus, with a focus on different genotypes and viral loads.
- - Conducted from 2002 to 2003 at the Autonomous University of Morelos State, the research involved 253 male students who completed surveys and provided samples; results showed a 19.4% HPV prevalence, with HPV16 being the most frequent subtype.
- - Key findings indicated that a history of STIs, female partner's use of contraceptive pills, and exchanging sex for money were significantly associated with HPV infection, with HPV16 having a notably higher viral load than other types.
Objective: To determine HSV-2 seroprevalence, risk factors, and antibody avidity among a sample of Mexican pregnant women.
Material And Methods: The avidity test was standardized with different urea concentrations and incubation times; the cut-off point was calculated to determine the low avidity (early infection). IgG antibodies against HSV-2 were detected from pregnant and postpartum women from Morelos, Mexico, and the avidity test was performed to positive samples.
