AIDS
1. AIDS is a sickness that attacks the body’s natural system against disease. AIDS itself doesn’t kill, but because the body’s defence system is damaged, the patient has a reduced ability to fight off many other diseases, including flu or the common cold. Since its discovery, AIDS has caused nearly 30 million deaths (as of 2009). As of 2010, approximately 34 million people are living with HIV globally. AIDS is considered a pandemic – a disease outbreak which is present over a large area and is actively spreading. Africa and South America are the continents where AIDS is most rampant.
2. So far there is no cure for AIDS. We know that AIDS is caused by a virus which invades healthy cells, including the white blood cells that are part of our defence system. The virus takes control of the healthy cells genetic material and forces the cell to make a copy of the virus. The cell then dies and the multiplied virus moves on to invade and kill other healthy cells.
3. The AIDS virus can be passed on sexually or by sharing needles used to inject drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her baby. Many stories about the spread of AIDS are false. One cannot get AIDS by working with someone who’s got it, or by going to the same school, or by touching objects belonging to or touched by an infected person. Nobody caring for an AIDS patient has developed AIDS.
