You can see the mortality rate for China is around 3.5% of those infected and the Rest Of The World which is under 1.5%.
Not only that, you can see a classic histogram curve from China which shows this flu virus is almost over.
The 'season' for flu viruses is coming to an end, and the warmer weather will further reduce deaths in the rest of the world.
BTFD !
