Bob died of pneumonia. That’s the cause of his death, but you don’t just “catch” pneumonia … pneumonia is caused by germs (bacteria, virus, food particles etc…) or chemicals getting into the lungs and causing inflammation, which results in fluid, shedding of dead cells, etc etc…:
the flu (including RSV in children)
pertussis / whooping cough
a cold (yes, just a common cold)
There are actually MANY different causes of pneumonia.
Please wash your hands and get vaccinated (if you can). You never know when you’re around an at-risk person (the young, the old, the immunocompromised, chronically ill, smokers, alcoholics, those allergic to eggs etc…) And if you’re out in public, you’re definitely in contact with at-risk populations.
If you’ve ever watched a “cold” or “the flu” make its rounds through a long-term care facility and kill 4 or 5 of your favourite old ladies … you know how important it is to do your part.
