Eli5; how we find “patient zero” when there is disease outbreak? (Like how they found who started the ebola outbreak in 2014)
In: 5171
I saw a pretty cool show on this before. SHort answer they genitically test it. As they get results globally, using transmission rates, and mutations, the can show what cities it spread from etc etc..the show was pretty damn cool. They showed the previous years flu epidemic and where each of the outbreaks started, how it mutated where it travelled to etc, and were able to, obviously speak to people who had it to find out where they travelled from, when they noticed syptoms etc etc…quite a bit of detective work…
