The coronavirus pandemic, caused by the SARS-CoV-2 virus, has emerged as a significant global threat to all countries and societies. Analyzing infection rates, mortality due to Covid-19, and the impact of vaccination, weather conditions, and demographic and ethnic composition on infection and mortality rates can provide crucial insights into this disease. SARS-CoV-2, the novel coronavirus causing acute respiratory syndrome, first emerged as a global pandemic in the Chinese city of Wuhan in December 2019. According to the World Health Organization (WHO), there have been 768,237,788 confirmed cases of Covid-19 reported worldwide, resulting in 6,951,677 fatalities as of July 19, 2023. Analyzing various factors like infection rates, mortality, vaccination, weather conditions, and demographics helps us understand the disease better. The United States has the highest COVID-19 death toll, while African countries have reported the lowest. However, Africa's high death-to-infection ratio might be due to inadequate healthcare services and vaccination rates, which require urgent attention. In addition, the relationship between environmental temperatures and COVID-19 cases and mortality is still under investigation.
