SUTRA MODEL

Subject : Science & tech

Context : Scientists see flaws in SUTRA’s approach to modelling pandemic.

Concept :

‘Susceptible, Undetected, Tested (positive), and Removed Approach’ (SUTRA) model

The model uses three main parameters to predict the course of the pandemic.
The first is called beta, or contact rate, which measures how many people an infected person infects per day.
It is related to the R0 value, which is the number of people an infected person spreads the virus to over the course of their infection.
The second parameter is ‘reach’ which is a measure of the exposure level of the population to the pandemic.
The third is ‘epsilon’ which is the ratio of detected and undetected cases.
