The incubation period of the common cold is typically 36 to 48 hours, but, in some cases, symptoms can arise within 12 hours, or slightly less, of catching the 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".
However, the incubation period differs depending on the specific common cold virus involved and the individual infected. There 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.
Adenoviruses: 2-14 days.
Respiratory Syncytial Virus (RSV): 2-8 days
Cold symptoms can also begin shortly after new virus particles are first produced in the nose (10-12 hours). The time from the beginning of the infection to the peak of symptoms is typically 36-72 hours. Adults can be infectious beginning a day or two before feeling any symptoms. Some people never develop symptoms even if infected allowing for more unknowing spread of the disease. The most contagious period is typically on the third day following initiation of symptoms.
Usually, yes. The most common causes are respiratory synsythial virus (RSV), parainfluenza viruses, influenza viruses. Metapneumovirus, human bocavirus, and a number of other recently discovered viruses are implicated as well.
