evidence: Scientists have cured a handful of people of HIV by piggybacking on treatments they received for blood cancer. But does that bring a widespread cure any closer? Over the past year, news of two new people cured of HIV grabbed headlines, stirring hopeful talk of what these scientific wonders might portend for the four-decade fight against the virus. [...] In July, at the International AIDS Conference in Montreal, researchers announced the case of a fifth person possibly cured of HIV. Diagnosed with the virus in 1988 and 63 years old at the time of his stem cell transplant three years ago, the American man is the oldest to have achieved potential success with such a treatment and the one living with the virus for the longest. Because of his age, he received reduced intensity chemotherapy to treat his AML. Promisingly, he still beat both the cancer and the virus.
