I am sorry if you misunderstood me.
A great number of surveys now, show that a lack of some nutrients (vitamins C & D, Zink...) make people much more likely to catch CoViD 19 than if they hadn't. (No combined survey to this date, as far as I know, only a number of surveys on each of these nutrients taken separately.) Which is consistent with theoretical models and previous surveys on other diseases. Yet, even with the right diet, a skater remains frail to any infection (caught at the moment or not long before) at the end of an exhausting skating session.
But once the bug is there, the status in vitamins (C?), D, K and in Zinc is a strong predictor of the outcome. So, if a skater gets it and becomes seriously ill, it may arouse suspicions, and even some judgement. I have said nothing more, because there is nothing more. As far as I know, there is no survey of the outcome of CoViD patients with or without a combination of all these nutrients, only each nutrient taken separately, and then, only on mortality, or need of ICU, or of hospitalisation, I have never read anything differentiating between mild and moderate symptoms, because it would be hard to avoid subjectivity, and also because few people use all their lungs and heart and stamina capacity everyday, so it seems to be generally thought that it doesn't matter. But as these nutrients are closely related to the need of hospitalisation or ICU, or to the risk of death, our mind tends to extrapolate and to think that an early administration of these nutrients may often advert a moderate illness, and tend to admit a sort of reciprocal, that a young person with moderate symptoms may have not had the right nutrients, and sometimes forget the "may"... hence suspicions.
About her value as a neurosurgeon, I can tell you that if she does become one (medicine students often change their initial preference when they discover other domains or admire a professor etc, I think otherwise there would be no great gynaecologist/obstetrician or gut specialist or other "less glamour" domains), I would certainly prefer (for myself) an intervention by her, even young and less experienced than others, than by a random neurosurgeon. I am sure she would be extremely serious and focused and intelligent and all what makes a great surgeon, and that her hands skill may match her legs one, which makes a dramatic difference even between great surgeons, and particularly in neurosurgery.
