According to UNAIDS (联合国艾滋病规划署) estimates, there were 38.6 million adults and 3.2 million children living with HIV at the end of 2002, and during the year 5 million new people became infected with the virus. Around half of all people who become infected with HIV do so before they are 25 and are killed by AIDS before they are 35.95% of the total number of people with HIV live in the developing world. But HIV still remains a threat to people of all ages and nationalities.
    Discrimination is the theme of the 2003 World AIDS Day. In many parts of the world, discrimination prevents people who are known to have HIV from securing a job or caring for their families. Discrimination can cause isolation. This can prevent people who have HIV and AIDS from being offered or seeking the treatment which could save their lives.
    In order for HIV to be effectively tackled on an international level, efforts need to be made to end the discrimination against people with HIV and AIDS; educate people in safer sex and drug use, using appropriate media; provide condoms freely to people in the developing world; provide financial and medical assistance so that people with HIV and AIDS can be treated.
    Started in 1988, World AIDS Day is not just about raising money, but also about raising awareness, education and fighting prejudice. World AIDS Day is also important in reminding people that HIV has not gone away, and that there are many things still to be done.
