Answer is............
NO, They are not.
HIV/AIDS sufferers are classified under the same banner as "people with communicable diseases" such as Yellow Fever,Typhoid etc.
Under Thai Law,if they have knowledge that you are suffering from HIV/AIDS you are not welcome.
It goes on to say that although a Doctor is not there to administer a test for HIV/AIDS when granting a visa, they may require a Doctors certificate and CAN request you to take a test,especially, if you wish to extend your visa and/or you apply for a long stay visa.
This, in effect, deflates wowpows argument, of the long term goal being to provide a two tier system whereby Thais who have no money, acquire the drugs very cheaply [cheap generics or stolen patents!!!] and middle class Thais and Foreign Residents pay the "going rate" for them!
Why??? Because Foreigners are not welcome if they have the misfortune of having this illness.
So, there you go!
I have never been aware that Foreigners had access to cheap HIV/AIDS drugs or any other drugs in this Country and relied on Foreign suppliers and Foreign clinics that deal with Ex-Pats such as the ones in Bangkok, to acquire the necessary drugs for Heart, HIV/AIDS drugs etc.
Amazing indeed!
