The aim of this study is to analyze the trend of spreading out coronavirus (COVID-19) for the second wave attack in Bangladesh during this winter season. In this study, we included all reported new confirmed and death cases from March 30 to December 14, 2020. Our intension is to explore the trend of dispersion in infected and death cases after January, 2021. In this paper, we have conducted statistical analysis of Covid-19 in Bangladesh to deliver with reliable and perfect forecasts of the outbreak. We used MS excel and SPSS software for regression analysis and found the slope of the trendline of the data and R-squared value for both infected and death cases. The new confirmed cases gradually increase with date (from March, 30 to June) and reach towards the peak for first wave attack. We get the slope of the trendline for infected case which is increasing first as 2    47.562, 0.8799 R and decreasing later as 2     20.709, 0.6816 R (from July to September) for first wave. After then again, the slope is increasing. Death cases are also following the same trend pattern. This analysis may help to take significant role for securing public health for Bangladeshi people. In this situation, Bangladesh needs to take emergency management system to protect the attack of the virus which we going to face for second wave. As well as people should concern about the guidelines provided by IEDCR and WHO up to get vaccine.
