What do you think of epidemic prevention and control at home and abroad?

For the domestic epidemic, China adheres to the consistent policy of preventing export from abroad and preventing spread within the country, promptly discovers, diagnoses, isolates in time, blocks the spread, and forms strong prevention and control measures. Most of the foreign epidemic control methods are based on China's prevention and control methods, especially China's makeshift hospitals, which have led the world. However, the United States' negative prevention and control measures have caused the epidemic in its country to spread very rapidly and the number of cases to increase sharply. Therefore, good epidemic prevention at home and abroad has a huge relationship with national policies and national unity, and China's anti-epidemic performance is an example.
