How long does a cold last?
Last updated September 3, 2026.
About a week for most people - symptoms peak around days 2 to 3 and fade over 7 to 10, with a cough sometimes trailing to two weeks. You are most contagious in the first 2 to 3 days and usually not contagious after the first week. Past 10 days without improvement, a returning fever, or severe sinus or ear pain means it is no longer just a cold.
What to do
- Ride the first three days at home if you can. That is peak contagion.
- Treat symptoms, not the virus. Rest, fluids, and over-the-counter relief - antibiotics do nothing for colds.
- Watch the 10-day line. No improvement by then, or improvement followed by a crash, earns a visit.
- Respect the one-sided signs. One-sided facial pain, ear pain, or shortness of breath are not cold symptoms.
