89. AIDS P.104

Each day， more than 6，000 people around the world fall victim to HIV. That's how serious the problem is. The World Health Organization has estimated that about 17 million people have already been infected with this disease. The news is that the virus is now spreading fastest in Asia. It's high time some steps were taken.

Two proven methods should be followed. One way is to teach people how to avoid catching the virus sexually through condom promotion. The other way is to encourage people to stop having casual sex. A word to the wise is sufficient， so don't take this warning lightly.
