VALDESPINO, José Luis et al. Seroprevalence of hepatitis C among Mexican adults: an emerging public health problem?. Salud pública Méx [online]. 2007, vol.49, suppl.3, pp.s395-s403. ISSN 0036-3634.

OBJECTIVE: Hepatitis C Virus (HCV) infection is becoming a chronic disease in 60-85% of individuals and is a cause of hepatic cirrhosis and hepatocellular carcinoma. The objective of this study was to report the seroprevalence of HCV infection in a probabilistic sample of the Mexican population. MATERIAL AND METHODS: This study is based on information obtained from the National Health Survey conducted in 2000. A total of 21 271 sera randomly selected for anti-HCV and RNA of HCV was studied. It was performed at the National Institute of Public Health in 2005. RESULTS: Seroprevalence of HCV antibodies was 1.4% (IC95% 1.1%-1.6%), of which 35.7% had active infection. Risk factors for infection were using heroine (RM= 9.8, IC: 2.1-41.4), being separated from his/her spouse (RM= 2.6, IC: 1.1-5.9), being a widower (RM= 2.2, IC: 1.1-4.3) and living in the northern states in the country (RM= 1.9, IC: 1.1-3.2). CONCLUSION: Results from this study indicate that HCV is an emerging public health problem in Mexico. Risk factors indicate that the main route of transmission is through transfusion of blood products (previous to 1996) and the second route is through usage of intravenous drugs and sexual practices.
