With the rapid spread of the variant strain Delta of SARS-CoV-2, some countries have shown a small rebound trend, and the global pandemic may face the risk of a third outbreak. As of September 4, more than 220 million people have been infected with COVID-19 and 4.5 million have died worldwide. According to the prediction results of the Global Prediction System of COVID-19 Pandemic (GPCP), in September, the outbreak resurgence would appear in many parts of the world, with more than 37 million cases estimated.
The world’s top 10 countries with the most projected new confirmed cases in September have been presented in Figure 1. It is shown that the US would remain the first. The outbreak in many European countries is likely to worsen in September. The COVID-19 is still raging in India, Thailand, Brazil and the UK, where the average number of daily new cases would remain more than 30,000. COVID-19 is still spreading in Iran, Spain and other countries. The global situation has also become more complicated.
