Presenteeism among healthcare workers can lead to burnout and healthcare-associated infections, but prior research has found that significant numbers of healthcare workers continue to work despite having influenza-like illness. This study surveyed 249 healthcare workers and 284 non-healthcare workers from 49 countries about their behaviors when experiencing influenza-like illness between October 2018 and January 2019. Overall, 59% of workers would continue to work when experiencing influenza-like illness, and the majority of healthcare workers (89.2-99.2%) and non-healthcare workers (80-96.5%) would continue to work with mild symptoms, such as a mild cough, fatigue or sinus cold.  Fewer non-healthcare workers (16.2%) than healthcare workers (26.9%) would continue working with fever alone.
