3.5.7 Match the sentences true or false
1. AIDS itself doesn’t kill. 2. Africa and South America are the continents where AIDS is most rampant. 3. There is a cure for AIDS. 4. We don’t know what cells AIDS can invade. 5. The AIDS virus can’t be passed on sexually. 6. It can be passed in blood products or from a pregnant woman with AIDS to her baby. 7. One cannot get AIDS by touching objects belonging to or touched by an infected person.

1) AIDS itself doesn't kill, but because the body's defense system is damaged, the patient has a reduced ability to fight off many other diseases, including flu or the common cold.
2) Africa and South America are the continents where AIDS is most rampant, although in the States alone about 50,000 people have already died of AIDS.
3) So far there is no cure for AIDS.
4) We know that AIDS is caused by a virus which invades healthy cells, including the white blood cells that are part of our defense 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.
5) The AIDS virus can be passed on sexually or by sharing needles used to inject drugs.
6) It also can be passed in blood products or from a pregnant woman with AIDS to her baby.
7) 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 and, since there is no cure for it at present, be as helpful and understanding as possible to those suffering from this terrible disease.
