your chances of dying is about 1 in 500
That is currently the worst case scenario death rate. The absolute ceiling to our estimates. The actual death rate will very likely be much much lower. Becuse we have no good figures on how many people are actually infected. How many infected have very mild responses and dont even show proper symptoms and so they wont seek help and wont get tested? That information will only be available months if not years later.
Swine flu has estimated 0.02% death rate now. When the 2009 pandemic hit, the panic was also great. The media reported death rate in the first weeks was also much higher than the actual rate turned out to be.
For an example lets say 10 people are hospitalised in a very serious condition. They get tested and turns out it is some sort of a new virus never seen before. 5 of them die before any new cases are discovered. The death rate will be 50%. But you have no idea yet if we have a world threatening pandemic on our doorstep or a very mild case of a 99.999% of the times an asymptomatic virus.
disproportional auto-immune reaction by the freaking out society
Sadly this is indeed the pandemic we need to react to time and time again. There however are some conflicting and potentially worrisome reports about the possibility of being re-infected, some concerns about long term complications and etc which should raise the severity of our response to this outbreak but not to the level of panic we are having now.
It is a good thing to move when seeing smoke but you dont want to start evacuating skyscrapers and hospitals every time someone smells something that could be smoke(er)
The smaller and more similar your group the easier it is to keep up unity and guard for any attempts of outside meddling. How could the natives even approach separate conquistadors to find anyone to be swayed? Aztecs had a big empire over a wide area with a lot of vassals. Cortes could easily approach them and make his sales pitch.
And sure technology played a role. Conquistadors were different, unknown and that made the sales pitch easier to make as they looked more powerful than they actually were. Plus they were a small outsider group. The natives that sided with them likely didnt fear them long term.
Conquistadors were not that alluring to French. They could never hope to do the same thing to a neighbouring country that is both powerful and hates your guts even if they found people willing. Plus a failed attempt like that would have meant retaliation against your own country which would not have been desirable. If their gambit had failed in Mexico there would have been no larger consequences. But it was still seen a lot in medieval europe. 100 year war was full of nobles switching sides like this. Almost a daily occurence in Holy Roman Empire throughout its existence. It was a slow day when one set of Princes didnt betray another set to join a third set to be betrayed and conquered by a fourth set.
