Depends on the density of the population in the area and weather (sometimes) and the how lethal the virus is. If a virus is dangerous enough to be called a pandemic, then it would have to have a good way of spreading like airborne or waterborne or carried by insects etc etc.
MY OPINION is that if there were no cure for cold but people continued their normal lives, I am guessing that the whole US will get a case of cold in less than two years.

∙ 12y agoIt varies considerably from virus to virus. Some will invade a host but stay dormant for a long time (even decades) before they start to reproduce, Herpes Zoster (Shingles) and the virus responsible for "cold sores" are examples of these. Some, like some types of the flu and the common cold, begin the replication process as soon as the host cell is invaded and can start to shed the virus in a matter of a few days.
