Mathematical analysis on bronchitis infection

Influenza is a very highly contagious respiratory disease. In this work, we are considering the population to treatment for influenza with secondary bacterial infection of bronchitis. The mathematical model constrains are number of susceptible(S), Infected with Influenza (D), Treatment(T), Infected with bronchitis(I
₂
), Recovered(R). The equilibrium and stability analysis represented in this work. This mathematical model concludes that the present situation of treatment is successful only 79.9%, so some necessary actions are required in this direction.
