Viruses cause such respiratory infections as the common cold (rhinovirus), the flu (influenza), some pneumonias and bronchiolitis (respiratory syncytial virus, or RSV). It can be difficult to determine whether you have a viral or bacterial infection because the symptoms are often similar.
Catching the Same Cold Twice: No, a cold is a viral infection, and once the virus has been in your system, you become immune to it if you have a healthy immune system.Therefore, if you are exposed to the same virus, it will have no effect because your body already has defenses built for it.However, you can catch a second kind of cold virus after having a different kind before. The reason this happens fairly frequently is that common cold viruses mutate quickly into new forms.his is probably why, once you are sick with a cold, you are less likely to get the flu or anything else at the same time since the immune system has already been alerted and is working hard. However, it is not impossible, it has happened.
