According to AIDS expert in Australia, the AIDS virus on the particular person is a result of defective mutation / strain. The lab should test the liver / lymph of the person to test if the virus still exist on his body.
Several people are born immune to HIV because of CCR5 negative gene. The HIV virus may develop slowly without becoming AIDS.
Major companies had developed new drugs targetting CCR5.
http://www.searchforacure.org/main.asp"Some people don't get infected with HIV - they are born immune. Scientists have figured why. Some people are born without a CCR5 receptor - a type of door on T cells.
Several companies are developing drugs which lock this 'door'. These drugs are called CCR5 'antagonists'.
Scientists are pretty sure these new drugs will be safe because they have studied people born without CCR5 receptors and discovered they are pretty much like everyone else - they don't die younger than other people, they don't get sick more often. They seem normal."

Because this class of drugs might be more powerful when used together, it is not a waste of time for each company to develop its own.
CCR5 antagonists are very different from any other kind of HIV medicine and because of this, might have some special uses as well as some special problems."
