This is the basic SIR model for COVID 19 where
  • Susceptible (S): This group comprises individuals who are susceptible to contracting the infectious disease. They have not been infected before and can become infected if they come into contact with infectious individuals.
  • Infectious (I): This group contains individuals who are currently infected and can transmit the disease the susceptible individuals.
  • Recovered (R): This group contains individuals who have recovered from the infection and may developed immunity to the disease, providing them the protection from reinfection
  • β: Infection rate
  • γ: Recovery Rate
  • N: Total population = S + I + R
