A study was undertaken among 118 children and 37 workers at a day care center to control an acute hepatitis focus by epidemiological surveys, physical examinations and the taking of samples for glutamic piruvic transaminase, immunoglobulin M dosages,  total hepatitis A antivirus, and surface antigen against the virus of hepatitis B, C and E. The hepatitis A virus was the cause of the outbreak. It was possible to locate the index case. All the infected by the hepatitis A virus were under 4. Most of the susceptible were children (96 %). 78 % of the adults were protected, showing evidences of previous contacts out of the outbreak. Those under 5 that were vaccinated according to the National Program Against the Hepatitis B Virus  had high values of seroprotection (over 94 %).

Keywords : Viral hepatitis; focus control; susceptibility; seroprotection.
