Acquired Immune Deficiency Syndrome or better known as AIDS is a life-threatening disease. It is one of the most dreaded diseases of the 20th century. AIDS is caused by HIV or Human Immunodeficiency Virus, which attacks the immune system of the human body. It has, so far, ended more than twenty-nine million lives all over the world. Since its discovery, AIDS has spread around the world like a wildfire. It is due to the continuous efforts of the Government and non-government organizations; AIDS awareness has been spread to the masses.
AIDS – Causes and Spread.The cause of AIDS is primarily HIV or the Human Immunodeficiency Virus. This virus replicates itself into the human body by inserting a copy of its DNA into the human host cells. Due to such property and capability of the virus, it is also known as a retrovirus. The host cells in which the HIV resides are the WBCs (White Blood Cells) that are the part of the Human Immune system.
HIV destroys the WBCs and weakens the human immune system. The weakening of the immune system affects an individual’s ability to fight diseases in time. For example, a cut or a wound takes much more time to heal or the blood to clot. In some cases, the wound never heals.
HIV majorly transmits in one of the three ways – Blood, Pre-natal and Sexual transmission. Transfusion of HIV through blood has been very common during the initial time of its spread. But nowadays all the developed and developing countries have stringent measures to check the blood for infection before transfusing. Usage of shared needles also transmits HIV from an infected person to a healthy individual.
As part of sexual transmission, HIV transfers through body fluids while performing sexual activity. HIV can easily be spread from an infected person to a healthy person if they perform unprotective sexual intercourse through oral, genital or rectal parts.Pre-natal transmission implies that an HIV infected mother can easily pass the virus to her child during pregnancy, breastfeeding or even during delivery of the baby.
