SARS-CoV-2 Incubation Period during the Omicron BA.5–Dominant Period in Japan
Tsuyoshi Ogata, Hideo Tanaka
Abstract
The mean virus incubation period during the SARS-CoV-2 Omicron BA.5-dominant period in Japan was 2.6 (95% CI 2.5-2.8) days, which was less than during the Delta-dominant period. Incubation period correlated with shared meals and adult infectors. A shorter incubation suggests a shorter quarantine period for BA.5 than for other variants.
