      You don’t just take the entire population and calculate the odds that they will contract and/or die of something. For instance, I could trivialize bike injuries/deaths in the US because countless people do not commute regularly on their bikes. Hell tens of millions don’t even have one and haven’t ridden a bike since they were children. The stat isn’t super useful unless we are discussing how many regular cyclists get hurt. Otherwise countless non-cyclists dilute the useful information - if they don’t ride bikes, they aren’t at risk at all. And that’s not even taking into account locale. Different population densities,topographies, etc. have different risks. But we can set that aside for now as I think you likely get what I’m driving at there.

      MRSA affects more specific demographics and conditions. Somebody who is older who contracts pneumonia and enters a hospital is far more likely than the average population to contract it - and it has a 10-20% lethality which is extremely high - so their risk has to be assessed in that context.

      If we only compared it against the general population, then hospitals would simply go “well in the grand scheme of things not many people die of MRSA.“ When what they’re (correctly) saying is “if you are elderly and have pneumonia we need to really watch out for MRSA.” Because that is a real risk.

      At 45 he’s not elderly but he’s within the range we see with MRSA unfortunately and pneumonia is a huge trigger for it (compromised immune system open to secondary infection). It’s incredibly resistant to antibiotics/cleaning supplies and is a real killer. Because hospitals clean so much it’s actually more likely to happen there than in “the real world“ because it gets selected out.

      So he isn’t super young (least contributing factor), he has pneumonia (big contributing factor), and is in a hospital (where it almost exclusively occurs). His odds were higher than that of the general population the same way if you go skydiving you have a higher chance of dying from falling to your death than the average population.
