> Viruses and bacteria can in fact be both extremely, extremely contagious and extremely, extremely lethal.
Sure, but those two things would tend to work against it becoming a pandemic— unless it managed those two things but also kept its host healthy enough for long enough before becoming lethal to adequately spread it.
I looked into this once, it depends on how splashy the death is. A virus that made people explode instantly into a fine mist of airborne virus particles could be perfectly adequate for a pandemic (although holding off until help arrives might work even better).
"A virus that made people explode instantly into a fine mist of airborne virus particles could be perfectly adequate for a pandemic"
And what existing virus comes close to this trait?
I think we can safely assume that OP was picking a bit of a ridiculous hypothetical example to make a point that it’s possible for something to be deadly and transmissible, although in nature Baculovirus in Caterpillars has a similar mechanism (encourages their host to eat a lot, then climb to the top of a plant so when it turns to ooze it infects others) or cordyceps although both of these aren’t as highly transmissible as they hypothetical explode virus.
But the Black Death mixed high contagion and high mortality as an actual example that shows they aren’t mutually exclusive.
