Lower incidence of the upper respiratory tract infections among general practitioners as compared to their patients

A retrospective cohort study suggest that general practitioners (GPs) run a significant reduced risk (more then 50%) to develop an upper respiratory tract infection (URTI) with fever compared to their patients. This difference can't be explained by variables such as gender, age, children and particularly young children, vaccination against influenza, presence of chronic illness or allergies, medication taken on a regular basis, smoking habits and regular physical exercise.
