You should feel comfortable going to most routine medical appointments like annual physicals and mammograms. The one caveat is the dentist. Although dental offices are taking precautions, they work in patients’ mouths and use instruments that can release droplets into the air. In that case, you may want to postpone your routine cleaning until a later date. You can call them to discuss it further.
