There are different investigations unfilled the population energetic of COVID-19. In this work, we formulate an approximated hypersingular integral based Chebyshev polynomials of second kind to simulate COVID-19 growth. The planned scheme indicates an association consequences of integral equation model by employing live data from Malaysia for three different months. MATLAB code is developed to obtain the numerical results for the presented problem. Moreover, the error function is applied to determine the compact interval of the infected number. We could establish agreement action on the displays where the numerical results assert the theoretical concept.
