The typical incubation period for a cold is 1-3 days. This means that it takes between 24 and 72 hours from the time you are exposed to the virus until you start to experience symptoms. Of course, this doesn't mean you will get sick every time you are exposed to a cold virus.
From the time a cold virus enters the nose, it takes 8-12 hours for the viral reproductive cycle to be completed and for new cold virions to be shed (released) in nasal secretions. This time period is called the incubation period.here are over 200 viruses responsible for the common cold. According to the US Centers for Disease Control and Prevention (CDC), the incubation periods for a few of the most common causative viruses involved with the common cold are: Rhinovirus: 2-7 days. Coronaviruses: 2-10 days.
