Three that I know of.
The Eurasian/African one that is the least dangerous and doesnt transmit human to human.
The continental Americas strain that is pretty dangerous(lethality in the 30-60% range) but doesn’t spread human to human.
The new kid on the block, the Andes strain, an offshoot of the Americas one. Last Outbreak was in a small town in Argentina in 2018, first discovered 1995, first human to human 1996. ~40 known infections, 11 deaths. Can spread human to human. It has already been confirmed we are dealing with this one.
There’s kind of two varieties. The Americas one is different to the other and was discovered more recently.
