Introduction: Congenital syphilis continues to be a public health problem in Mexico., Objective: To assess the similarities and differences between national standards, guidelines and international documents related to the detection of syphilis in pregnant women and congenital syphilis., Method: Two algorithms were developed based on the standard of female care during pregnancy and on the standard for prevention and control of sexually transmitted infections. Based on the Centers for Disease Control (CDC) guidelines, algorithms were developed for syphilis during pregnancy, syphilis in the newborn and sexual contacts., Results: The standard for pregnancy mentions that syphilis testing should be carried out in every pregnant woman on her first contact or at delivery, without diagnostic tests being specified. The Official Mexican Standard (NOM) on sexually transmitted infections mentions the traditional algorithm for syphilis detection, treatment follow-up, coinfection with human immunodeficiency virus and congenital syphilis criteria. The CDC recommend reverse algorithm, antibody titer, treatment and follow-up as part of diagnosis., Conclusions: The elimination of mother-to-child transmission of syphilis requires NOMs updating and homogenizing, as well as the study of stillbirths and neonates born to mothers with syphilis., (Copyright: © 2019 Permanyer.)

Introduction: herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) are the most frequent sexually transmitted infections (STI) among college students 18-24 years old. Educational interventions for STI prevention can help to decrease viral STI prevalence among students., Objective: to know the change in knowledge, perception of risk and sexual behavior among 182 students of the Autonomous University of the State of Morelos., Material and Method: a community intervention trial (before-after) was carried out, using brochures for prevention of HSV-2 and HPV, including information about these STI, with emphasis on the risk factors identified in students of the same university., Results: we found a change in the perception of STI risk during the intervention (56.5 before vs. 67.7% after intervention), possibly the brochures assisted students to learn more about their own risk behaviors. Likewise, there was an increase in knowledge in both HPV and HSV-2., Conclusions: it is necessary to increase the sample size in future interventions to assess further the change in knowledge, sexual behaviors and the prevalence of infections.

Objective: To perform a hepatitis B, C, and HIV survey in an enhanced sample from two rural communities with the highest anti-HBc prevalence found in ENSA 2000., Materials and Methods: This was a cross-sectional study.We studied the communities of La Calera and Cuambio, two adjacent rural towns of the district of Zirándaro, Guerrero, targeted because of the high prevalence of anti-HBc shown in ENSA 2000.We assessed the prevalence of hepatitis B and C, and HIV serological markers and associated factors among inhabitants older than 10 years., Results: A very high prevalence of hepatitis B markers associated with socioeconomic factors was confirmed, while hepatitis C prevalence was low and HIV absent in the two communities addressed., Conclusions: National serosurveys are an accurate tool for identifying communities with hepatitis B high endemicity where focused research and control measures are needed.
