How dangerous is it to have a virus?

Most doctors will tell you that the most dangerous part of having a virus is the fact that it will normally put your immune system in a very vulnerable state. This means that your body may not be as capable of fighting off bacterial invasions as it normally would. For instance, a person who is perfectly healthy and not suffering from any sort of virus or illness will usually be able to effectively fend off malicious germs that may enter his/her body. A person who has a compromised immune system due to the overload that occurs from trying to kick a virus out of the body will not be as successful at fighting off secondary illnesses. This is why many doctors routinely hand out antibiotics whether they suspect a virus or a bacterial infection. It is important to be aware that there are a couple of different schools of thought where over prescribing antibiotics are concerned. Some doctors do not like to prescribe antibiotics unless they are 100% sure they are needed as there is always a chance that a person can become immune to specific antibiotics after prolonged or continuous use. The best way to prevent secondary infection if you have a virus is to minimize your contact with the outside world during your illness. It is also vital that you drink plenty of fluids, allow your body plenty of rest and get ample amounts vitamin C.
