In b4 pappy dogs say, we followed WHO guidelines
About 1-2 months ago, India only clocked about 10-25K cases in Feb/Mar.
Then in early April, it started to have 100,000 daily cases. Thereafter consistently 300,000-400,000.
In a normal situation, infection rates will increase gradually like a drop of ink spreading in water. Based on data science, the sudden increment in April was a sudden spike up and sustained, meaning to say that the hibernation period is about 4-weeks or more.
The mutation in India may not become more lethal but it hibernates for a longer period of time for the infected person to go around spreading it. The covid cases in the past 2 weeks were probably the first-batch infected (4-6 weeks ago) and now they start to fall sick.
If this hypothesis is true, then we will see the spike in Singapore after end-May.
