However, this action did not have the desired effect since AIDS continued to spread throughout China. From 1988 to 1993 most of those being diagnosed were intravenous drug users, and it was also common for new cases to be in the Yunnan among sex workers, people seeking treatment for sexually transmitted diseases, and Chinese people who had been employed abroad. Unfortunately, by 1998 AIDS had spread beyond coastal cities and Yunnan to all the regions of China.
