For just the second time since the global epidemic began, a patient appears to have been cured of infection with H.I.V., the virus that causes AIDS.
The news comes nearly 12 years to the day after the first patient known to be cured, a feat that researchers have long tried, and failed, to duplicate. The surprise success now confirms that a cure for H.I.V. infection is possible, if difficult.
Yes! Scientists have long tried to duplicate the procedure that led to the first permanent remission 12 years ago. With the so-called London patient, they seem to have succeeded.
