We all thought that my dad was going to die from covid19. The doctors were very pessimistic. He lived. He recovered very slowly over the last 4 months. During the first month, he could not speak English (he was born in Norway), he needed 3 liters per minute of oxygen, and he could not stand up. Now, he has no trouble speaking, does not need oxygen, and he can walk 300 yards if he has a walker. Every month he has improved.
