I had a case of prolonged respiratory inflammation last spring. Put me off the bike for 6-7 weeks and off the work for nearly 3. During my sick leave I used taxi or bus to get to doctor's appointments and did my grocery shopping during those trips. Many of my friends also called regularly to see if I needed anything. Considering the medication I was taking, I doubt it would have been a good idea to drive even if I had a car.
