The incubation period of 2019-nCoV infections among travelers from Wuhan, China

Category: Article Summary

Topic: Modeling and Prediction

• Based on travel history and symptom onset of 34 confirmed cases detected outside of Wuhan during Jan 20-23, researchers estimated a mean incubation period of 5.8 days (95% CI, 4.6-7.9) with a range of 1.3-11.3 days. These cases were likely infected in Wuhan. 
• Details for modeling the incubation period are included as well as a table comparing mean incubation period estimates across studies of 2019-nCoV, SARS-CoV, and MERS-CoV.
