Any HIV therapy that reduces the risk of an immune cell being infected by a factor of at least 100,000 is enough to keep the virus in check, researchers reported.

And the model also demonstrated that the complexity and cost of HIV treatment might be reduced -- and access to treatment improved -- by choosing drugs based on their ability to inhibit infection, Siliciano and colleagues reported online in Nature Medicine.
