I don't know if anybody here can enlighten me, but I thought I'd give you guys a toss at it....
In a couple of discussions, I've heard references to some individuals being subject to high levels of 'viral loading' without showing any symptoms. From the contexts I've run across this, it seems to mean that some individuals become exposed repeatedly and garner multiple sources of infectious agents, even of the same particular strain of a single virus, like the coronavirus. The impression I'm getting is that some individuals are massively overloaded with a virus and either a danger to themselves, when they are finally brought low, or to others, upon whom they are shedding their vast excesses of the virus.
Google was not particularly helpful in that is directs to the concept as used in HIV infections as being the presence of the infectious agent in the blood, by a count per ml of a blood sample. No indication of how that relates to multiple sources of infectious agents, but does allude to a level within a given victim's blood stream.
I'm inclined at the point to dismiss my interpretation as a boogie man...that there are Typhoid Mary types out there spreading the infections. I probably misread something.
Of course, with no real testing to rely upon, it is a moot point.

With all of the millions of viruses out there, it wouldn't surprise me if some individuals are harbouring several viruses at the same time, even to the extent that they feel at a low ebb throughout the Winter. But I've not heard of viral loading and so I don't know how it affects the ability to transmit infection..

This is interesting. I read an article the other day (but can’t find it now) suggesting that viral loading was the reason why young healthcare workers were getting sick and dying from CV19.
It went against what I thought I understood about catching a virus, i. e that exposure was exposure, regardless of how many or few people you got it from. How sick you got depended on your own body’s response. The article seemed to suggest that healthcare workers got sicker because they had been exposed more often and to more virus than casual exposure.

Yep...That's the kind of thing I also ran across. In two separate articles.

Here... This seems to be addressing that same issue.

That's a very interesting article, WG.

I notice that, in response to a possible SARS-like infection, the Taiwanese Disease Control Department published a response strategy to Covid-19 and started screening of fever for inbound passengers and quarantine measures for passengers from Wuhan... on 31 December last year... three weeks before it detected its first case. Wow! www.cna.com.tw/news/firstnews/201912315004.aspx

It sounds like a logical theory. As a teacher I came across lots of viruses every year, but I'd generally feel perhaps a bit blue but otherwise fine. Once every 3 or 4 years or so, I'd be very very ill from a simple flu. I guess at some point the bomb has to burst.
