An Invasion of Infiltrators

Why might a species be invasive in one country but not a big problem in its native land? As an example, consider a plant that is a major weed in the U.S. but in its native land it may be a minor pest. Many weeds have chemical defense systems that make them taste bad. In the weed's native land the animals that feed on the weed often evolve along ...

Fighting Viruses

FightingVirusesViral diseases can be very difficult to treat because viruses live inside the body's cells where they are protected from medicines in the blood stream. Researchers developed the first antiviral drug in the late 20th century. The drug, acyclovir, was first approved by the U.S. Food and Drug Administration to treat herpes simplex virus infections. Only a few other antiviral medicines are available to prevent and treat viral infections and diseases.

Health care professionals treat HIV infection with a group of powerful medicines which can keep the virus in check. Known as highly active antiretroviral therapy, or HAART, the new treatment has improved the lives of many suffering from this deadly infection.

Viral diseases should never be treated with antibiotics. Sometimes a person with a viral disease will develop a bacterial disease as a complication of the initial viral disease. For example, children with chickenpox often scratch the skin sores caused by the viral infection. Bacteria such as staph can enter those lesions and cause a bacterial infection. The doctor may then prescribe an antibiotic to destroy the bacteria. The antibiotic, however, will not work on the chickenpox virus. It will work only against staph. Unfortunately, safe and effective treatments and cures for most viral diseases have eluded researchers, but there are safe vaccines to protect you from viral infections and diseases.
