What Killed George Washington?

I don’t know if anyone knows for sure what killed our first President, George Washington. We do know he fell ill starting as a sore throat. As the hours passed he became sicker and weaker, hardly being able to speak. Excepting his own fate, that his time was near. He didn’t believe in taking medicine. Now was it a case of Strep throat, Influenza, epiglottis or something else that lead to his demise. That mystery may never be solved.
