Christian Chenay is almost old enough to remember the 1918 Spanish flu, and treated typhus sufferers during World War Two. Now, as he nears his 99th birthday, the French doctor is still caring for patients through the coronavirus epidemic.
Dr Chenay holds virtual consultations for patients, some of whom he has treated for decades, over the phone and internet, and is back to making weekly visits to a retirement home for clergy after a brief spell in quarantine.
But he had to halt appointments in his surgery in Chevilly-Larue, a Paris suburb, last month after two patients turned aggressive, demanding he hand over his small supply of face masks.
