What are the facts about the Common Cold Incubation Period?

Normally the common cold incubation period ranges from about two to five days but what must be noted is that its symptoms can appear in as little as a few hours, once the virus first enters the body. This is mostly explained by the large variation in viruses that can cause the symptoms of common cold. Some of these viruses can cause the symptoms to appear much faster than other viruses. Another explanation for the huge range of the incubation period is that some people who have the virus do not show the symptoms. This makes it harder for the medical practitioners to speculate a precise incubation period.

Rhinoviruses were first injected into the nasal pathways of volunteers in clinical trials and almost all of them became infected. Some scientists argue that people with a strong immune system do not develop the symptoms while others say that common cold is actually initiated by the functions of the immune system. To eject the virus out of the body, the two most common actions carried out by the body is sneezing and coughing.
