TY - JOUR AU - Ogata, Tsuyoshi AU - Tanaka, Hideo T1 - SARS-CoV-2 Incubation Period during the Omicron BA.5–Dominant Period in Japan T2 - Emerging Infectious Disease journal PY - 2023 VL - 29 IS - 3 SP - 595 SN - 1080-6059 AB - 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.
