So this is scary

This is an exponential curve: This is an exponential curve: Worldometer This is also scary... Age chart This is one explanation why estimates of mortality ratios vary from 1% to 6%. It depends which age-group the infected people are in. There's an age bias in infection rates across age groups as well. The median age group for infection is 51. (There are as many people infected older than 51 as there are younger.) As average (mean) age is around 72, there are many more people under the age of 51 than over it, so it seems you're much more likely to be infected if you're older, and more likely to die of Covid-19 the older you get. (I'm not yet in the over-60's group, but not as safe as an 8-year-old.) "World is approaching coronavirus tipping point, experts say"

Wuhan novel coronavirus 2020

... if nothing was done. Google sheets has an extrapolation function for exponential growth based on a limited amount of data. The results are alarming, but it is to be hoped that action to inhibit the spread of the virus will flatten out the curve. Seems quite likely at the moment that the damage to global supply chains caused by China's almost complete shutdown may cause more harm than the virus itself. Left unchecked, the result would be catastrophic. The kink in the graph may be a good sign. The red curve is where the exponential function says it should be, based on the recent data. The blue is based on date from the beginning of the reported cases. It shows where cases would be if no intervention had taken place and the virus had proceeded unchecked. The curve flattening out is either because intervention is reducing the rate of infection, or because the Chinese Communist Party's internal police are frightening people into not giving true numbers... we'll k...
