[Absenteeism and influenza. Analysis of relationship between the excess morbidity and the influenza phenomenon].

The results are reported of a survey on the influenza phenomenon made on a sampling of about 100,000 subjects from the FIAT working community. The study is based on the absenteeism information for both over and under three days absence, for the time period between October 1976 and April 1977. In addition, a tentative evaluation of the influenza phenomenon has been made not only for the overall working population but also for various age groups.
