COVID-19 incubation
Data about interval from {exposure} to {symptom onset}
  • The median incubation period was estimated to be 5.1 days (95% CI, 4.5 to 5.8 days)
  • 97.5% of those who develop symptoms will do so within 11.5 days (CI, 8.2 to 15.6 days) of infection.
  • These estimates imply that, under conservative assumptions, 101 out of every 10 000 cases (99th percentile, 482) will develop symptoms after 14 days of active monitoring or quarantine.
