The COVID-19 outbreak originated from Wuhan, China has spread over the world, causing a "Global Pandemic". We analyzed daily confirmed cases and deaths from different countries to understand the progression of the ongoing pandemic in different parts around the world. The data indicated that the pandemic is in different stages in different countries, where they are either at the end of the second wave or middle or early phase of it or still in the middle of the first wave of infection, and they can be divided into four groups. Type 1 countries such as UK, France, Spain, and the Netherlands are currently witnessing the second wave of infection with an exponential increase in daily cases. Countries such as Australia, United States, Japan, and Poland are currently in the declining stage of second-wave, grouped as Type 2 countries. Type 3 countries such as Germany, Italy, Belgium, and Russia are recently seeing the second wave with slowly rising of confirmed cases. Type 4 countries including India, Brazil, Argentina, and Mexico are currently fighting against the first wave of COVID-19. These countries have a chance to learn from the countries which have overcome the second wave successfully. To be ahead of the epidemic curve and preventing it, countries need to make future plans on family, hospital, and community levels. Isolation of the highly vulnerable elderly people and young children, preventing social or public gathering, following the guidelines of COVID-19 prevention including wearing face masks regularly can save countries from devastating effects of the second wave of pandemic COVID-19.
