Sarin said, Delhi had recorded its first coronavirus case on March 3 and mathematical modelling of the pandemic from China suggests that it takes about 10 weeks for the epidemic curve to decline.
What is flattening the curve?
The curve is said to flatten when the reproduction number is one. For example, 10 people giving the infection to only 10 people.
What is a declining curve?
If the reproduction number is less than one, meaning 10 people (primary cases) passing on the infection to less than 10 persons, say 8 people (secondary cases) and those persons, in turn, passing it on to less than eight people, and so on.
In India, the reproduction number for coronavirus cases is ranged from 1.7 to 2.5, he said.
