Question: Is AIDS still a risk for couple who have normal male/female sex?
The risk in western countries of transmitting AIDS from one person to another is highest in injecting drug users and homosexuals, but it is still a problem with heterosexual sex. The saying that when you have sex with someone, you are biologically having sex with every other person that your partner has had sex with, is still true. Although less than one in ten AIDS cases occur from heterosexual sex in western countries, there is still the risk of other sexually transmitted diseases.
In Africa and Asia, the situation is vastly different, with virtually all cases of AIDS occurring with male/female sexual contacts. In some African countries, up to one in three people in the entire population have AIDS, while in southeast Asia one in 20 people in Cambodia are infected.
The incidence of AIDS has steadily dropped for several years in developed countries with better education, and safe sex techniques (eg. using condoms) but seems to have reached a plateau now, with new cases being diagnosed at about one third the rate they were at the peak of infections in the early nineties. About 600 people a year in Australia catch AIDS every year.

Question: Where did AIDS come from? I believe it is a divine retribution from God against those who have sinned. What do doctors really known about the history of AIDS?
The story begins in Central Africa, where it is now believed a mild form of AIDS has existed for centuries. This mild form (known technically at HLTV one) has been isolated from old stored blood samples dated in the 1950s. From Africa, it spread to Haiti in the Caribbean. Haiti was ruled by a vicious dictator (Papa Doc Duvalier), and many Haitians fled to Africa to avoid persecution.
Once ‘Papa Doc’ and his son ‘Baby Doc’ were removed from power, these exiles returned, bringing AIDS with them. In the process, it mutated (to HLTV three, now known as HIV) and became mote virulent, causing a faster and more severe onset of symptoms. Viruses mutate routinely (eg. different strains of influenza virus every year).
There may also have been some movement of the disease directly through Africa to Algeria and France.
American homosexuals frequented Haiti because it was very poor, and sexual favours could be bought cheaply. They returned home from their holiday with the AIDS virus, and it has spread around the world from there. The first cases were diagnosed in California in 1981.
Fortunately for most of us, it is a relatively hard disease to catch. AIDS can NOT be caught from any casual contact, or from spa baths, kissing, mosquitoes, teats, towels or clothing. Only by homosexual or heterosexual intercourse with a carrier of the disease, of by using contaminated needles or blood from a carrier can the disease be caught.
Many people who are not homosexual, promiscuous or drug addicts have been affected by this dread disease, including a number of of Australia’s haemophiliacs, who depend upon blood products to stop them bleeding excessively.
