Numerical modeling on age-based study of coronavirus transmission

Ethiopia is one of the countries highly affected by COVID-19 pandemic in Africa. A new study has looked at transmission dynamics outbreak based on age categories infected individuals. Infected individuals are divided into three (less than 14 years (I1), 15–54 (I2), and above 54 I3). Chebyshev polynomial fourth kind used to convert a fractional system an algebraic equations, which then solved using iterative methods. The fundamental reproduction number (R0) calculated next-generation matrix technique, disease-free endemic equilibrium points, as well their stability, carefully studied. We parameters starting conditions provided for our model data from Ethiopian Public Health Institute (EPHI) Ministry 29 February 2021, 7 June 2021.
