title: [Surveillance of viral hepatitis in Argentina: analysis of information from sentinel units 2007-2010].
abstract: In Argentina, the four strategies of epidemiological surveillance from the National System of Health Surveillance (SNVS) are Diseases of Mandatory Report (C2), Sentinel Units (SU), Laboratory Surveillance (SIVILA) and National Programs (National Plan of Blood, information from blood banks). They collect information about viral hepatitis (VH). The objective of this work was to analyze the information recorded by the SUs of VH for hepatitis B and C in the period between January 1th 2007 and December 31h 2010. In this period, out of the 1,769 cases recorded (entered by 21 of 24 SUs), 806 entries were hepatitis B, 848 hepatitis C and 115 belonged to other definitions. The relative proportions between hepatitis B and hepatitis C were heterogeneous between the SUs. The age distribution was homogeneous, being the predominant group in acute hepatitis B the 25- to 34-year-old group. In hepatitis C, the age distribution was broader. The distribution by sex and risk factors was heterogeneous between the different SUs. In hepatitis C, genotype 1 was the predominant one. In conclusion, the information provided by the SUs contributes as an evidence of the public health problem posed by this pathology in our country.
