Gosh, how old are you? You've never smoked and have emphysema? Are you around smokers? I've always read that second hand smoke can also cause emphysema in people.

So, yes, having a lung condition will put you at greater risk. https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/people-with-medical-conditions.html You need to make sure to socially distance, be around people who take it seriously and wear a mask and avoid anyone sick or outside your circle socially if you can.
