SUTRA Model:
-
SUTRA is a mathematical model used for charting the trajectory of COVID-19 in the country.
-
SUTRA stands for Susceptible, Undetected, Tested (positive) and Removed Approach.
-
Parameters: The model uses three main parameters to predict the course of the pandemic:
-
Beta or contact rate: This measures how many people an infected person infects per day.
-
Reach: It is a measure of the exposure level of the population to the pandemic.
-
Epsilon: It is the ratio of detected and undetected cases.
