Can you tell me, are their medicines that prevent hiv from ever turning into aids?

Yes.: There are many medications that halt the progression of HIV infection. These drugs are known as "antiretroviral" medications. When two or three drugs are taken together in combination, they can suppress viral load to undetectable levels and stabilize patients, allowing for decades of essentially normal life. These drugs must be taken faithfully and as prescribed, and they are not a "cure"...
