Certain strains of the herpes virus cause cold sores. Herpes simplex virus type 1 usually causes cold sores.
simply because there are hundreds of different strains of cold virus. viruses that causes colds are among the most active in terms of mutation hence it is really hard to control and monitor them. when you had a cold a month ago and had contracted again after recovery, the very reason for that is that you have been infected by a different type of cold virus.ever wondered why there are no drugs available in the market that really "cures" colds? simply because there are a lot of strains in existence and you cannot possibly have a "cure-all" medicine for all types of cold virus. :-)

Yes a virus does cause the common cold.
The common cold is a virus. There are multiple strains of this virus. Anyone who is infected by a strain to which they have not already been exposed will become ill. Once you have recovered your body will have adapted to that particular strain and will be able to fight it immediately should it ever attempt to infect you again. However, you will still be susceptible to "catching" a new strain. Science does not yet know of a way to destroy a virus without also destroying the cell it has infected and so there is no "magic cure" for a cold.
