This telugu newspaper says artesunate has been very effective in curing COVID-19 but Govt. of India and the world ignored this.

^^^Similar thoughts (about WHO) have been expressed by others who have studied the data and IMO knows much more than I.

Vayutuvan - More I think about it, (and many others are also saying this) it almost seems cruel - Both Penrose and Hawkins ought to have gotten it in Hawkins life time.

Then Pi(x) - Li(x) > 0 is true for x =1, 2, 3,...
