One variable that is still not known and would make a huge difference is how many people are asymptomatic and with that catch this and have no symptoms. That effects infection rates and also getting a better grasp upon how many recovered as well as infected. Not just a case of testing those for infection, that cat left the bag in every country on that end. Need to also test for those who are now immune without being aware. Otherwise may well see spreads more than expected due to these people spreading the virus when they have no symptoms and also prevent paralysation of those who are immune, isolating when they don't even know they had it already. So knowing that variable will become key in tackling this and currently we have no idea upon that.
