Which is skewed because there is NO way we know the true number of cases out there. We are seeing the numbers from those who have been tested. (1) Not everyone is going to seek out medical assistance and testing especially when they have a mild case and (2) we did not test for a VERY long time. This has already been in the US for months. We just did not know it for sure because we did not have a test. Someone's cold? Or flu? Or upper respiratory infection? Could have easily been Covid19.
The absolute spike in critical case hospital care in China, Italy, Iran, and now the Us though does show a very rapid and very severe sudden explosion in cases. While it may have been circulating and misdiagnosed in the very early stages and mild cases not noticed, we would not have missed hundreds of people in one community suddenly needing emergency care. We would not have missed a nursing home losing 15% of their residents in 2 weeks. We would not miss otherwise healthy health care workers suddenly contracting respiratory illnesses. All of those things have occurred in the last 3 weeks (6 weeks for China). Based on the rapid/exponential hospital spikes its difficult to say this has been in communities for months and everyone just had mild cases but suddenly we have hundreds of severe cases.
The death cases aren’t the big showstopper at these current raw numbers, the hospitalization numbers appearing in isolated communities are what has health experts and governments shocked and point to a serious epidemic.
