With the accelerated spread of the global epidemic, Beijing, as an international exchange center, cannot completely end the epidemic prevention and control in a short time, and is likely to be in the state of epidemic prevention and control for a long time, which is determined by the complexity, long-term and arduousness of epidemic prevention and control in the capital. Therefore, in line with the normalization of epidemic prevention and control, we should continue to adhere to the overall prevention and control strategy of "external defense investment and internal defense rebound", scientifically and accurately analyze and judge the epidemic trend, and adhere to strict prevention and control.
