To whom it may concern,
We really appreciate your attention and patience! Please accept our sincerest apology for the delay in releasing prediction results after more than 10 days of the current COVID-19 outbreak. Since its launch on May 25, 2020, the Global Prediction System for COVID-19 Pandemic of Lanzhou University has conducted 16 predictions of accidental outbreaks in China, which has received wide attention and support from the society. However, we are still regularly upgrading and improving the prediction system in order to improve the prediction accuracy. When the current COVID-19 outbreak occurred, the system was being improved and upgraded. The complicated travel routes, various affected provinces and multiple branches of the spread of Delta variant have brought new challenges and pressures to the epidemic prediction. While actively cooperating with Lanzhou's epidemic prevention and control policies, we urgently analyzed the transmission chain and development situation of this round of epidemic. As we upgraded our systems, we made epidemic predictions for 6 provinces and 7 cities involved in the current epidemic and the whole country. Based on the analysis of the transmission chain and development trend of this round of epidemic, combined with our preliminary researches, we put forward relevant epidemic prevention suggestions, hoping to be helpful to the domestic prevention and control of the epidemic.
