A picture, a calendar or even a balloon may be the best way for millions of people living in China's vast
country areas to learn about AIDS, one of the biggest threats to public health in the world today.
China has decided to use user-friendly methods including exhibitions, VCDs and TV programmes to
spread knowledge of the disease across the nation to try to keep it in check.
Educating people nationwide about AIDS is the top priority (优先权) to prevent the disease from getting
out of hand. The farmers will be given knowledge in the easiest way that they can understand.
A recent survey from the commission (调查团) of more than 7,000 people in China showed that nearly
20 percent of them had never heard of AIDS before. Just over 71 percent said they knew AIDS was highly
infectious (传染), but most of them had no clear idea of how the disease could be spread. Just over 62
percent said they knew they could do things in advance to prevent them catching AIDS but they didn't know
what these measures were.
The month-long survey, carried out last December, talked to people in seven countries and cities across
China including both developed coastal areas and less-developed inland areas. The interviewees changed from
15 to 49 years old, and country residents were about 63% of the total surveyed.
Chinese residents, especially those in the country, have very little knowledge about what AIDS is all about,
not to mention prevention and treatment. By the end of last year, there were 22,517 known HIV\AIDS cases
in China. However, more than 6,000,000 people in China have been infected.
Since 1985, China has discovered 880 patients with AIDS-466 of them have died. Sharing needles,
prostitution (卖淫) and contaminated blood transfusions are major ways for HIV to spread. A lack of education
has been the biggest difficulty against nationwide efforts to prevent AIDS, especially in the countryside.
