Is there any truth to the rumors that there are new strains of the common cold?

Yes, there is some truth to the rumor. There have been several recent studies on how viruses mutate and evolve over time. These studies show that certain types of viruses can become more virulent or more contagious when they mutate. This means that a virus could potentially become more deadly or spread further if it mutates in a way that makes it easier for people to catch.
