I dont know how 1 million is a possibility, if they claim we are going the way of china and Italy they then it should peak out in 2-3 weeks so if that is very true 1 million is an extremely extremely extremely extremely fabricated number to even predict.
I am sorry but China data is not reliable since the Party is covering up a lot. Italy is more reliable (I live in Italy) but the lock down you have in place in some stated in the US is way less severe than in Italy (or Spain for that matter).
Italy has still a long way to go and it is emerging that the number of deaths is quite much higher than as reported since many people are now dying at home without reporting or being tested. This is happening for two main reasons: hospitals admit patients only when the symptoms are very serious and for a number of people that is too late.
Also since once admitted to the hospital you won't be able to see your loved ones many people decide to die at home in the care of their loved ones. It is very sad but it beats the terror of dying alone on an anonymous bed in a hospital.
I hope the number in the US (and in all countries for that matter) will be much lower but I have little hope since the lock down measures are designed to delay the contagion (and hence allowing hospital to care for the many patients) not to stop it long term.
