The problem is, and I know you will hate to hear this, is that these sorts of anecdotes may or may not mean anything. Symptoms like that have a long history of turning out to be false alarms. That's the reason medical trials have placebos: health is weird and people can cure themselves or make themselves sick from all kinds of ways that logic dictates shouldn't happen, like 'thinking' themselves into it, or just via random chance.
Does COVID-19 cause breathlessness in a tiny percentage of people who caught it? Possibly, it's a respiratory virus after all. Does it cause loss of concentration? Hmm, maybe, who knows. The body works in mysterious ways. But if it can cause that then more or less any symptom at all is fair game.
Seen another way, do people with wifi sensitivity truly feel headaches when wifi is turned on? They certainly believe they do, their suffering seems to be real, yet we know their self-diagnosis cannot possibly be correct ... at least not without significantly rewriting the laws of physics and biology as we know them.
It may be that your wife should lose the Slack group and see a doctor. The risk is that the collection of symptoms she's reporting (which have no known link with respiratory diseases) actually have another cause and COVID is a distraction. It could be an undiagnosed case of something else that needs attention. We know that COVID is being spuriously linked in the media to all kinds of random conditions and symptoms, and especially when in a community of other sufferers, it's possible for incorrect inferences to be made.
