Everyone is busy discussion where the virus came from, and if it was man made or intentionally released or not.
But the real cover up is that some countries are affected very badly, like Ecuador and China. And others aren't! Look at Nicaragua with only 1 reported death!
Places like the US and India appear to be doing lock down and social distancing as a cover for why they aren't badly affected. If India doesn't do anything and they aren't affected by the virus, the whole world will look at them and wonder what about them is different.
I would expect a cover-up would first try to blame a naturally evolved 'virus'. If that didn't fly, I would expect the story to shift to a 'bio-weapon'. I would expect China to 'fess up' to it being their 'research' and 'our bad' whether that is the reality of the situation or not. This is somewhat more palatable to them politically than a hit to the confidence of their public health system, and it is vastly more palatable to other partners around the world.
An even better strategy would be for the Chinese to 'mildly resist' it being the 'Wuhan BL4 lab' in the face of 'obvious' evidence to that effect. 99.9% of people will take their 'resistance' as a sure sign that they have something to hide and are thus 'guilty'. One way or another, expect all efforts to be made to completely bury their mandatory vaccination program which, at least according to some, shifted legally on exactly the day that the illness first popped up.
I think this is a very good prediction of how the cover up is and will continue to go on. They're even willing to take some blame to keep people away from the truth.
