OBJECTIVE To measure hepatitis C virus (HCV) sero-prevalence, prevalence, hepatitis risk characteristics frequency, and genotype correlation with viral load among clients attending health care clinics. MATERIAL AND METHODS Venous blood samples from l12 226 consecutive consenting adults were collected from January 2006 through December 2009. HCV antibodies(More)
OBJECTIVE To estimate the prevalence of maternal and neonatal syphilis, to assess the usefulness of a rapid treponemic diagnostic test, and to evaluate the frequency of screening for syphilis during prenatal care in Mexican women. MATERIAL AND METHODS This was a cross-sectional study that included 1,322 women interviewed in two hospitals (Hospital General(More)
BACKGROUND AND AIMS Treponema pallidum can cause syphilis in pregnant women and congenital syphilis in the newborn. In Latin America, 330,000 pregnant women are diagnosed with syphilis every year. Adequate prenatal care to detect syphilis reduces maternal morbidity and fetal and neonatal mortality and morbidity. We undertook this study to determine T.(More)
OBJECTIVES This study tried to determine human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevalences among female commercial sex workers in Mexico City. METHODS A sampling frame was constructed that included bars, massage parlors, and street corners. RESULTS Prevalences for Treponema pallidum, herpes simplex virus type 2, HIV,(More)
Hepatitis A virus (HAV) remains a public health concern worldwide contributing to significant morbidity in developed and developing countries. This cross-sectional database study estimated the overall HAV seroprevalence and the seroprevalence by gender, age, region and socioeconomic status in Mexico. Between January and October 2010, serum samples collected(More)
BACKGROUND Drug resistance of hepatitis B virus (HBV) is an increasing clinical problem. Resistance to lamivudine in HBV isolates in Mexico has been poorly explored. OBJECTIVES To characterize the mutation patterns associated with genotypic resistance to lamivudine and their prevalence among HBV isolates in Mexico. MATERIAL AND METHODS Thirty-nine(More)
OBJECTIVE Assess frequencies of maternal and congenital syphilis, mother-child transmission and variables associated with syphilis in six urban hospitals in Bolivia. MATERIAL AND METHODS A cross-sectional study was performed between May and September 2004. We administered the Abbot Determine-TP rapid test and quantitative RPR to postpartum women without(More)
OBJECTIVE To study the distribution of the hepatitis B antibody (anti-HBc) based on a national serosurvey from 10 Mexican states showing a mean HBV prevalence higher than the national one. MATERIALS AND METHODS This was a cross-sectional study. During 2003, anti-HBc was analyzed at INSP in 19 907 sera, and the related sociodemographic factors were(More)
