F I G U R E 4 COVID-19 incubation period (IP) according to age in previous and present studies: (A) mean or median age, (B) percentage aged ≥ 65 years. Substudies are indicated by arrows from main study. "Age" refers to age of study sample of incubation period when available, or to age of parent sample when age is not available for study sample. Although previous studies on COVID-19 incubation period did not look specifically at the effect of older age on incubation period, I reviewed these studies for any such clues. Of the twelve studies 5,12-20,22-23 on COVID-19 incubation period ( Figure 4) , it was noted that the incubation period for the severe group (whose subjects were older with median age of 61.4 years and 43.5% aged over 65 years) had a longer median incubation period of 7.5 ± 7.2 days when compared with 6.5 ± 4.6 days for the milder group (whose subjects were younger with median age of 44.5 years and 13% aged over 65 years). The study by Qin et al 22 reports on a long COVID-19 incubation period (mean 8.29 days; median 7.76 days) that is close to the present figures, but their sample was younger (median age 40 years, 13.2% aged over 60 years) and a different methodology was used as discussed above.
