There are key differences between HIV and a regular virus. The body is able to adapt to the genetic makeup of a regular virus, and know how to obsolete it as a result. However for HIV, it is a constantly mutating virus in that the body's immune system cannot keep up with its roulette of genetic makeup.
HIV attacks the immune system directly
HIV attacks helper T cells that are trying to fight infection, rather than attacking healthy body cells like a cold virus does. HIV attacks lymphocytes directly.

A person has to be infected with the herpes virus (type 1) to get a cold sore.
That's a fine description of the "common cold".
Every virus is different. Some are infectious for only a couple of days; some are infectious until after your body has been buried. Some may be infectious for longer than that; bodies of the victims of the 1917 influenza strain have recently been exhumed, and were discovered to STILL be dangerous.
A cold virus can typical live for a day in a medicine bottle. This virus cannot last longer than this without a host.
Usually disease can be contracted through air or fluids. Through human to human it is more often airborne than fluid borne.
The herpes that causes cold sores remains in the nervous system and is reactivated from time to time. The sore reappears at this time. A cold virus doesn't act this way in the nervous system. Once a person has a cold, that person makes enough antibodies so that the virus doesn't cause a cold again in that person.
Usually a cold virus take from 3-5 days but depending on the virus and the human body differences it can take less than a day. Some bodies attack the virus quickly giving you symptoms faster.
Here are some examples of airborne viruses that cause infectious diseases in humans: •The common cold (there are more than 100 different viruses that cause the cold) •Pneumonia (there are more than 50 different viruses that cause pneumonia... pneumonia can be caused by a virus and/or bacteria) •Hepatitis B •Mumps •Measles •Small Pox •Influenza (including the Swine Flu H1N1) Hope this helps!!!!!!
You can't. Your body needs to take time to produce the necessary antibodies, which is how your immune system fights a common cold. That can take from 7 - 10 days for a typical common cold virus. You can treat the symptoms and begin to feel better sooner than that time frame, but each individual will take different times for the development of antibodies and this can vary depending on the specific cold virus involved.
Because the virus will mutate. When you get the flu more than once each time it is a different virus.
