MERS, and SARS data has been published multiple times. For this new beastie we were at 3% early last week when fatalities were still sub 50. (A Google search will list many reports of that value.) 5% is the common number now being used as the documented fatalities pass 100. It's a conservative estimate too considering that yesterday there were 80 recorded fatalities and today we are at 100+. We are in the early stages so we are going to see incremental bump ups. Nothing unusual about it either. Yesterday, before the latest batch of dead bodies was cataloged, the WHO used a fatality rate of 4%. You can listen here https://www.pscp.tv/WHO/1LyxBNMYqXkxN
Some people are still relying on initial WHO comments about the illness which WHO has now retracted and admits were overly cautious.

The point here is that;
1. This is not a campaign against China and;
2. This is not similar to the seasonal flu.
