That is a lot of guys and no one is perfect. You didn't mention your age, that is okay, but patients with RA may be at greater risk of more severe infections. That is because of the autoimmune disease itself plus the medications used to treat RA and the person's lifestyle.
Droplets from an infected person's cough or sneeze can fall on objects that another person may touch hours later and that person could touch his/her eyes, nose or mouth without thinking.
Longer term RA patients may have lung and heart problems. People over 60 are also at more risk of infection. Feel free to call your Rheumy about this.
Your wife with COPD is definitely a high risk patient for Covid-19 and not recommended to be near other people. My Sister has this disease. I do not mean to scare anyone but some people are carriers with mild or no symptoms. Many companies do deliver to homes, as you know.
One of my Specialists called me from her home for my appointment, since she did not want any of her patients to possibly catch anything from other people at the hospital.
Thank you for your question and please do take care.
