What are some of the most common infectious diseases?
Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, smallpox, and Ebola. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves.
What are some examples of viral diseases?
Examples of diseases that are viral in origin are influenza (swine flu), some types of pneumonia, poliomyelitis, cold sores and shingles, and AIDS (acquired immunodeficiency syndrome). Of course, host cells have several defenses against the viral attacks.

What is the difference between a virus and a disease?
A disease is a condition that impairs the body ‘s normal function resulting in the distinguishing symptoms. A virus is infective and is just as in our computers, a code that can multiply while living within the host. RNA or DNA surrounded by a coat of protein that invades, the virus cannot replicate without a host.
How are diseases caused by a virus?
Viruses cause disease by invading host cells, then taking over the cell and causing it to create more viruses. The immune system has a variety of ways of detecting that a cell is infected by a virus.
