Patient’s immune system ‘naturally’ cures HIV in the second case of its kind



In 2013, doctors delivered a life-altering diagnosis to a woman in Esperanza, Argentina: She had acquired HIV, the virus that causes AIDS. Eight years later, the virus has all but disappeared from her system. 

In fact, stunned researchers were unable to find evidence of any HIV viral particles in her body, “despite analysis of massive numbers of cells from blood and tissues, suggesting that this patient may have naturally achieved a sterilizing cure,” they wrote on Nov. 16 in the journal Annals of Internal Medicine. However, they cautioned that science cannot definitively prove that no trace of the human immunodeficiency virus remains.
