Rt is a measure of how quickly a virus spreads, representing the average number of people
who catch the virus from one infected patient.
A low value of Rt indicates that the social distancing and lockdown are effective while a
high value indicates that the social distancing measures are poor. When Rt is below 1, it is a
good indicator that the outbreak is under control.
