Return to work following sickness absence due to infectious mononucleosis.
BACKGROUND
Epstein-Barr virus infectious mononucleosis among adults is notorious because of the prolonged incapacitating fatigue it causes.


OBJECTIVE
To investigate the duration of sickness absence and return to work following infectious mononucleosis.


METHODS
Episodes of sickness absence due to infectious mononucleosis were selected from an occupational health services register. The duration of sickness absence and return to work was assessed with Kaplan-Meier survival analysis.


RESULTS
Two thousand one hundred and thirty-seven episodes of absence due to infectious mononucleosis had a median duration of 91 days. Young employees (aged 15-24 years) had the highest return to work rates. Women had longer sickness absence than men. Employees working in small companies were absent longer than employees in large companies.


CONCLUSIONS
Occupational physicians should advise gradual return to work, starting 4 weeks after the onset of the illness, in order to prevent physical deconditioning and prolonged illness.
