How did Isaac Asimov die?

Isaac Asimov died on April 6, 1992, at the age of 72. He succumbed to renal failure, a consequence of a long-standing battle with HIV/AIDS. He contracted the virus through a blood transfusion in 1983.

It's important to note that Asimov was very private about his illness, choosing not to publicly disclose his HIV diagnosis until after his death.
