I tried to find out if any health authorities are actually recommending that. The closest I could find is the World Health Organisation which says people with COVID-19 should wear them, and healthy people in contact with people with COVID-19 should wear them. I can't find any mention of people with chronic illness.
Therefore, that's a definite I don't know.
So as always, check with your doctor if you have the opportunity, and make whatever you feel is the best choice for your health.
I do know that using a mask incorrectly can increase the risk of infection. If the virus is on the mask, that is rubbing against your face, that's a risk factor. If you're using one, be careful to do it correctly.
Here's the WHO's advice on who should wear a mask.
And, importantly, here is how to use one properly.
If you need to make your own, and can sew, you'll find a pattern here: https://freesewing.org/fu-facemask-freesewing.org.a4.pdf. The instructions to go with the pattern, if needed, are here: https://freesewing.org/docs/patterns/fu/
Remember if you're using a reusable mask, it will need to be washed or, soaked in disinfectant prior to washing, as soon as it comes off. Be careful how you handle it until it's clean, and wash your hands.
Stay safe out there lovely lupies. We're going to get through this.
Just saw this video from the Lupus Foundation of America, in which Duane Peters from the Foundation asks Rheumatologist Dr Blazer about safety going out, and she recommends masks and gloves.
