- Some 14.1% of health care workers (HCWs) were attending work while ill with influenza.
- Approximately one-quarter of medical doctors were working while ill with influenza.
- Full-time HCWs had significantly shorter sick leave duration than part-time HCWs.
A high prevalence of working while ill (presenteeism) has been documented among health care workers (HCWs). However, previous evidence is primarily based on nonspecific causes of sickness and self-reported data. Our study examined presenteeism among HCWs with laboratory-confirmed influenza.
