During the COVID-19 pandemic, is it safe to go to the doctor (General Practicioner) for a regular check-up?

I am a diabetic, with other complications (high cholesterol, High blood pressure) who did not get a good report as far as diabetes goes about six weeks ago. Furthermore, I have been away from home the past eight or nine days helping with Tornado recovery efforts in Nashville.

I have a follow-up doctor’s appointment on Tuesday. To be honest, I am afraid to go—I know doctors are taking all precautions, but I still think a doctor’s office is one of the worst places to be if one is not sick.

I have two elderly, vulnerable parents who are extremely susceptible—my father has a compromised immune system due to chemotherapy—both my parents are in their eighties with mobility problems and rely on me. Contracting the virus would be deadly to them.

My girlfriend, whom I share an apartment with, probably doesn’t have much of an immune system either since she never gets out and has stayed in the apartment for the past month.

How safe is going to a general practitioner who normally treats the sick, if you are only going in for a check-up? Should I cancel and reschedule?
