Function of the Immune system
Explain why antibiotics are effective against bacteria but not against viruses.
Define pathogen, active immunity, passive immunity, antigen, and antibody.
Active immunity - the immunity that results from the production of antibodies by the immune system in response to the presence of an antigen.
Passive immunity - the short-term immunity that results from the introduction of antibodies from another person or animal.
Antigen - a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
Antibody - a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
Symptoms: Fever, Fatigue, Swollen lymph nodes (often one of the first signs of HIV infection), Diarrhea, Weight loss, Cough, Shortness of breath.
Common: Every 9½ minutes, someone in the U.S. is infected with HIV. It is estimated that there are over 56,000 new cases of HIV in the U.S. each year. It is estimated that 1.7 million people in the U.S. have been infected with HIV since 1981 and approximately 1.1 million Americans are currently be living with the infection.
Treatment: This is the main type of treatment for HIV or AIDS. It is not a cure, but it can. stop people from becoming ill for many years. The treatment consists of drugs that have to be taken every day for the rest of a person’s life. The aim of antiretroviral treatment is to keep the amount of HIV in the body at a low level. This stops any weakening of the immune system and allows it to recover from any damage that HIV might have caused already. The drugs are often referred to as: antiretrovirals, ARVs, anti-HIV or anti-AIDS drugs.
