I found the article below interesting, given my minor Coronavirus symptoms, which the lack of smell. I exposed to CONVID-19 in what I would deem a limited way. Curious about the degree of exposure, I did a bit of digging for journal articles regarding the strength of viral exposures and the trajectory a disease takes.
It does appear that there is a strong correlation between disease severity and the initial viral load. In simpler terms, the more one is exposed to a virus, the more dangerous it is.
Below is the title, the authors, and a link to the article itself, that you may find useful and informative.
