ICMR in daily briefings had said we will get 0 new cases by 20 May as per their mathematical modeling.
I don't know much about that, but this is my personal view. please go through this thread from start, when I warned initially everywhere everyone put silly logic to deny the truth. If ICMR had some magic wands which CDC doesn't have, I would agree. The steep rise in cases worrisome.
Anyway these are just theories, but again not impossible!!
