What are viruses?
Viruses are infectious agents that multiply inside living cells. All viruses have the same basic structure, but their shape or size may vary.
How can you treat a virus?
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.
How can viruses cause disease?
Viruses can cause disease in a variety of ways, including:
- - Viruses may destroy or disrupt the activity of the cells they invade - this can be serious if vital organs are affected
- - Your immune response (defence) may lead to symptoms - fever and fatigue
- - Through interaction with the chromosomes of the host cell - i.e. viruses can cause cancer
- - They may cause disease by weakening the immune (defence) system allowing other illnesses to develop - as in AIDS
- - The body's defence against virus invasion is fairly rapid, but a virus can hide from the immune system allowing the infection to recur or become chronic
