This is a really important question, and the short answer is: possibly, but it's complicated.
Research suggests that certain viral infections may play a role in triggering RA in people who are already genetically predisposed to it. COVID-19 is among the respiratory viruses that have been looked at in this context. Here's what is currently understood:
- The immune system's response to a virus like COVID-19 can sometimes cause it to mistakenly attack healthy tissue
- This process, called molecular mimicry, is one way infections may contribute to autoimmune conditions like RA
- Not everyone who gets COVID-19 will develop RA — genetics and other environmental factors also play a role
- The connection between specific infections and RA development is still being actively researched If COVID-19 occurred before RA symptoms appeared, it's worth mentioning this to a rheumatologist. Even if it's just noted in a medical chart, it could contribute to ongoing research efforts.
What is well established is that COVID-19 can trigger RA flares in people who already have the condition — as one myRAteam member shared, their RA became very active immediately after contracting COVID-19.
