- Scientists from the IITs of Kanpur and Hyderabad have applied the ‘Susceptible, Undetected, Tested (positive), and Removed Approach’ (SUTRA) model to predict the COVID graph in India.
- 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.
