What is AIDS?

AIDS or Acquired Immune Deficiency Syndrome or acquired immunodeficiency syndrome is a disease of the human immune system which is caused by the human immunodeficiency virus also known as HIV. This situation gradually reduces the efficiency of the immune system and leaves individuals prone to various infections and tumors. According to the statistics about 2.1 million people are died because of AIDS which also includes children. For more information on Aids click here to see Aids Powerpoint Presentation.

Though the gradually spreading of disease can be controlled through treatments on AIDS and HIV but there is no cure and vaccine till date. There is antiretroviral treatment which reduces both the mortality and the morbidity of HIV AIDS, but these drugs are costly and everyday access to antiretroviral medication is not available in all the countries. 

As there are difficulties in treating HIV AIDS prevention is the best way to control AIDS. Many health organizations are promoting safe sex and needle-exchange programs in attempt of HIV AIDS. 

Awareness about aids can help to reduce the widespread of AIDS up to some extent. Also if one million people are suffering from aids and if they are ignorant then at least more than 50 % will also infected by aids. Thus there should be lot of awareness for AIDS and one should avoid contact with HIV positive person.

How AIDS transmits?

 HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can involve anal, vaginal or oral sex, blood transfusion, infected hypodermic needles, exchange between mother and baby during pregnancy, childbirth, breastfeeding or other exposure to one of the above bodily fluids.

However there are no documented cases of HIV being transmitted by tears or saliva till date, but it is possible to be infected with HIV through oral sex or in rare cases through deep kissing, especially if you have open sores in your mouth or bleeding gums.

Taking preventive measures and awareness can help reduce HIV AIDS as “prevention is better than cure”.
