Pooled average incubation period of COVID-19 is about 6 days

Objectives:
What is the incubation period of SARS-CoV-2 (COVID-19)?  

Study design:
This review article included 18 studies, representing 22,595 participants.

Results and conclusions:   
The investigators found pooled average incubation period of SARS-CoV-2 was 5.7 days [95% CI = 5.1 to 6.4].

The investigators found subgroup analyses by geographic location showed that the pooled average incubation period of SARS-CoV-2 was 6.1 days [95% CI = 5.34 to 6.94] in China and 4.54 [95% CI = 3.9 to 5.2] in other countries (Singapore, South Korea and globally).

The investigators concluded pooled average incubation period of SARS-CoV-2 (COVID-19) is about 6 days. The longest incubation period has been observed in China. Global health initiatives as well as local health planners should consider this average incubation period when designing optimal prevention and control strategies for SARS-CoV-2.
