I probably err on the side of caution. With mild COPD--found this out from my oncologist, and a weakened immune system, plus pushing 70 years of age, I have been avoiding being among others--especially groups since this virus (viruses) appeared. It may be overkill, but I'd rather be safe than sorry. My advice to you is to skip PT until the Corona Virus settled down--it will stop, especially with warmer weather coming.
