The number of tests of few states have actually come down. This is being counterbalanced by some state(s) like UP. Though I really doubt the authenticity of those tests after a recent video leak. If you see the positivity rate has indeed gone up.
Also, if the recovery rate is so high, how come the death rate is almost constant? Secondly, how come we see a sudden spike in recovery rates, though the infection spread is still 80k+. Without the advent of some miracle drug, this sudden uptick in recoveries is just not possible. As other conditions like infrastructure, temperature etc is almost constant. Another act of God?
