The 174 days’ daily data have been taken from the website of worldometer Bangladesh from 10 March to 30 August, 2020 for the analysis. To analyze the trends and to identify significant changes in trends joinpoint regression analysis has been used. Results: The number of cases increased by the rate of 4.98 percent per day in Bangladesh, however, from 11th June to 30th August i.e. for 81 days, the growth rate is found negative means we observed a decline in the COVID-19 cases per day with the rate of -0.6 percent.
