Should I stay home from work with a cold?
Last updated September 3, 2026.
If you can, yes for the first 2 to 3 days - that is peak contagion and usually the worst-feeling stretch. If you cannot, the CDC's minimum bar: symptoms improving and 24 hours fever-free without medication, then 5 more days of mask, distance, and handwashing, since a cold stays contagious through its first week. The productivity math agrees: sick days cost less than a half-speed week plus three sick coworkers. Fever, chest cough, or vomiting are home-day symptoms regardless of culture.
What to do
- Guard days one to three. Peak contagion and peak misery overlap - that is the stay-home window.
- Meet the bar if you must go in. Fever-free without meds, improving, masked in close quarters.
- Handwash obsessively. Cold viruses travel on hands and surfaces as much as air.
- Draw the severity line. Fever, deep chest cough, or stomach symptoms: home, full stop.
