Viral Incubation Periods^a

Virus	Median (Range) Incubation Period
Adenovirus [23]	5.6 days (4.8–6.3 days)
Coronavirus [23]	3.2 days (2.8–3.7 days)
Influenza A [23]	1.4 days (1.3–1.5 days)
Influenza B [23]	0.6 days (0.5–0.6 days)
Parainfluenza [23]	2.6 days (2.1–3.1 days)
Respiratory syncytial virus A and B [23]	4.4 days (3.9–4.9 days)
Rhino/enterovirus [23]	1.9 days (1.4–2.4 days)
Metapneumovirus [23, 24]	Not available (3–6 days)

^aViral incubation included in this table correlate with the viruses detected on the laboratory respiratory viral panel, rapid influenza, and rapid respiratory syncytial virus tests used in this study. There has been no established incubation period for metapneumovirus in the literature, and the range is based on reported cases.
