I closed a topic about this earlier because I felt the topic would raise people’s anxiety.
As the issue isn’t going away, I think it’s worth revisiting the subject to say that it’s well documented that people who have our condition often feel better after or even during an illness, including myself.
We don’t know what the reason for this is, but as @bunny88 says, it’s more likely that our bodies aren’t reacting in the same way as before, rather than there being some kind of super hero response to illness where we have attained some sort of immunity.
At this point, I am of the opinion that everyone here should be mindful of the official advice from your health authority regarding the Corona Virus and that while we have no indication that pfs patients should consider themselves at greater risk, being vigilant and careful is in your best interest.
