And of course you will probably acquire an additional runny nose virus, due to the fact that there remain several hundred different cold infections. But you will unlikely get the exact same cold infection that you had previously due to the fact that you have actually developed immunity to that particular cold virus.Parents have previously had a lot of the runny nose viruses. Grownups have established resistance to the viruses they have actually suffered from. Therefore there are not so many runny nose infections around for adults to catch. That is why parents just get infected with a couple of colds per year whereas children get 10-12 runny noses per year.
