A way to decrease HIV and AIDS would be to educate and learn. You may or may not know that HIV and AIDS can be transmitted through sex and other things as simple as just drinking out of the same water bottle. There have been many breakthroughs and set backs including AIDS and HIV. Many sexual related cases includes failing to wear a condom or inform the partner if he/she is aware they are infected. However some people are just born with it and can not do anything about it. It can also occur with improper living conditions, one of the places it is most commonly found is in Africa because they only have a few places with clean drinking water and proper shelter. One of the common species that spreads it often are bugs, most typically mosquitos. They bite someone with aids, then they bite another person without aids and then the person without suddlenly has it. Although it can be years before you know you have it. It is an estimated 7 or so years after every sexual partner before you know you have AIDS or HIV. However most cases have begun to decrease in most regions but is still here. It was a goal to have it stopped by 2010 but that did not happen.
