One of many growing health concerns today is the transmission of HIV/AIDS. It is estimated that some 33 million people are infected with AIDS. AIDS is a condition caused by the human immunodeficiency virus or HIV. Acquired immunodeficiency disease or AIDS is a condition that characterizes later stages of HIV infection.
The early stage symptoms (those shown approximately four weeks after infection) of HIV can be mistake for the common flu and some experience no symptoms in the early stages.
HIV, upon entry into the body, attacks the immune system by infiltrating the lymph nodes and killing off helper T cells, more specifically the CD4 lymphocytes. These cells are important for the coordination of the entire immune system. Some may remain symptom free eight to 10 years after initial infection with HIV until AIDS has developed. By this time, the immune system is severely compromised and opportunistic infections, or those that attack during time of weakened defenses, may occur. Symptoms during this stage include swollen lymph nodes, persistent fatigue, chills, distorted vision and more.
HIV can be transmitted through sexual contact, blood to blood contact, infected needle sharing and from mother to unborn child. Having unprotected sex places you at an increased risk for contracting HIV. There is no cure for HIV and the best outcome for those infected with the virus can be a long battle with the use of drugs to try and prolong the spread and development of AIDS.
In the '80s, when HIV was discovered, there were few drugs to help fight the disease, but now drugs have been much improved. Sadly, after 20 years on some medications, some people have been shown to develop resistance and new research is always being conducted to find new and improved drug treatments.
