According to this article in The Bangkok Post, 1.2 million Thais contracted HIV between 1984 and September 2008. Of those 92,111 have already died. Included in the numbers of the infected include 10,728 government officers. 90% of the total number contracted HIV, the virus that can lead to AIDS, through sexual intercourse.
As I wrote earlier, the HIV infection rate in Thailand presents great challenges to the current government and a great deal of attention needs to be paid regarding how to provide anti-retroviral medications to all of these people, as Thailand currently does.
A topic of much debate (at least at my university) is regarding the overall health care system in Thailand. The government of Thaksin Shinawatra created a 30Baht (.90 cents U.S) universal health scheme. Many middle class Thais feel that they already pay way too much tax to a government that redistributes it disproportionately to the poor. I tend to disagree and personally am happy to pay tax here knowing that it is going to helping people who really have nothing.
