Common cold incubation is up to 3 days. Covid's incubation period is usually 5 - 6 days. In the case of both the common cold and Covid coronaviruses there can be no symptoms at all throughout the infection.
So, that is a difference. Anyway, thanks
On average, symptoms showed up in the newly infected person about 5 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14. In rare cases, symptoms can show up after 14 days. Researchers think this happens with about 1 out of every 100 people.
