viral diseasesDiseases caused by viruses. Long-term immunity usually follows viral childhood diseases (see chickenpox). The common cold recurs into adulthood because many different viruses cause its symptoms, and immunity against one does not protect against others. Some viruses mutate fast enough to reinfect people after recovery (see influenza) or to keep the immune system from fighting them off (see AIDS). Certain cancers are caused by viruses. Vaccines can prevent some viral diseases. Most recently developed antiviral drugs work only against specific viruses; antibiotics are ineffective against viral diseases. See also poliomyelitis; smallpox. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |
