Viruses are minute infectious agents that multiply inside living cells. They are so small that most can only be seen with an electron microscope. Their sole activity is to invade cells of living organisms which they take over to make copies of themselves. All viruses have the same basic structure but their shape or size may vary. Unlike bacteria viruses cannot be grown in culture and antibiotics are not an effective treatment against them. There are some anti-viral drugs now available that work by either preventing viruses from entering a cell or by altering their ability to replicate.
Viruses can cause disease in a variety of ways:
The body's defence to virus invasion is fairly rapid but a virus is able to hide from the immune system allowing the infection to recur or become chronic.
