Before revision:  However for other countries, it is almost inevitable to see the continuation of the outbreak in the coming months. Japan and Italy are in serious situations with no short-term end to the outbreak to be expected. There is a significant risk concerning the upcoming July 2020 Summer Olympics in Tokyo. Iran's situation is highly uncertain with unclear and negative future scenarios, while South Korea is approaching the end of the outbreak. Both Europe and the USA are at early stages of the outbreak , posing significant health and economic risks to the world in the absence of serious measures .
After revision:  However for other countries, it is almost inevitable to see the continuation of the outbreak in other countries. We identified that Europe and US have passed the inflection point and entered into an after-peak trajectory, which is estimated longer than what a classical Logistic model predicts, in contrast to most provinces in China where the after-peak trajectory is much faster. We expect Europe to have 1.83 million final total confirmed cases (2452 per million population) and US to have 1.26 million final total confirmed cases (3851 per million population). We identified three groups of countries in different level of outbreak progress, and the USA are at early stages of the outbreak , posing significant health and economic risks to the world in the absence of serious measures .
