Can you develop a cold nine days after exposure to someone with a cold?

Yes, it is possible to develop cold symptoms nine days after exposure to someone with a cold. The incubation period for cold viruses, such as rhinoviruses, typically ranges from 1 to 3 days, but symptoms can sometimes take longer to appear depending on individual factors and the specific virus involved. Additionally, if you were exposed to multiple viruses or your immune response is delayed, it could extend the time before symptoms manifest.
