Students in Kazakhstan were asked to express their ideas with chalk
Have you ever heard of disease called smallpox? You may not have heard of smallpox because a United Nations agency called the World Health Organization (WHO) helped wipe out the disease. The last case of smallpox occurred in 1977. 
 
In "World without AIDS through the eyes of the children," the United Nations asked students in Kazakhstan (Central Asia) to express their ideas with chalk.
