The mortality rate of both appears to be the same. Ease of transmission appears to be similar too, in that people are transmitting the virus without showing symptoms. That’s what makes it dangerous. One undetected person can spread a lot of flu if they or authorities don’t know they have it.
Then there is the intentional terrorist wave to worry about. A suicide bomber mentality with only a 2.5% risk factor ups the ante a lot.
That’s what that death cult in Korea is doing. Purposely infecting Christians to bring about the end times. Can’t make this shit up.
Ease of transmission isn’t even close.
The 1918 flu was spread by migratory birds.
