I see that the USA now appears to be the main hot-spot for coronavirus.
Looking at the data currently (11:00 GMT on Sunday 22 March) on **LINK** , and on the pages linked from there for individual countries, USA is making rapid headway up the chart.
Future projected levels must be approximate, but:
China currently has 81,054 cases, daily increase around 0.05%, so expect around 81,200 in 4 days time
Italy has 53,578 cases, increasing around 14% per day, so around 90,000 cases in 4 days time
USA has 27,111 cases, but increasing around 35% per day, so also around 90,000 cases in 4 days time
So by next weekend, the USA looks headed to be the worst affected country in terms of total number of confirmed infected cases.
I suspect the figures are generally very suspect, in terms of unreported (and generally milder) cases. For example, Italy has a very high death rate, implying true infection rates are much higher.
I better not comment about leadership of the USA! 
It also cannot help that the USA does not have a modern healthcare system freely available to all, as is available in Europe.
