Thank you! Will do a deeper dive on this, much obliged. I've been trying to keep up with the research, but wasn't certain whether a person could recover and then weeks or months later have a relapse of symptomatic fatigue without other symptoms, or a cluster of symptoms. It's that temporal gap that has me squinting, but the fatigue from seemingly nowhere, weeks after a more-than-mild second infection screams covid to me.
Nobody in my circle takes my concerns seriously, & I fear for them.
