[Africa CDC/Mastercard Foundation] I remember my first COVID-19 patient. She was 16 and I was called to see her after she had been admitted to hospital. Alone in her hospital room, she looked scared. Though I tried to hide it, I was too. I was, after all, knowingly entering the same room as a COVID-positive person. At that time, we knew little about this highly contagious virus, and a vaccine was months away--at best.
