title: [Serological markers of hepatitis B and C, and HIV in La Calera and Cuambio, Guerrero, México].
abstract: 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.
  
  
  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.
