I'm actually curious: how many 'virus particles' does a person need to be exposed to on average to contract the virus?

  The keyword you may be interested in is "viral load", and AFAIK we do not have much data on this, as it's extremely difficult to measure. https://timesofindia.indiatimes.com/city/delhi/why-viral-load-is-tough-to-detect/articleshow/78454509.cms https://timesofindia.indiatimes.com/city/delhi/why-viral-loa...

  Challenge trials in animal models suggest somewhere in the 100-1000 range. Lower initial does also seem to lead to less severe courses of disease.

  Surely only 1 is enough, otherwise how does the first one spread in the first place?

    There should be some culminative chance distribution that starts at 1 virus ye.
