Coronavirus in China: travel restrictions should continue to avoid a resurgence, researchers say

Chinese researchers said allowing for the movement of people to Covid-zero regions like China would result in 234.2 million infections and 2 million deaths within a year.

The key to controlling Covid-19 lies in the development and widespread use of vaccines that are more effective in preventing infection, said a research paper published in China CDC Weekly, a bulletin of the Chinese Centre for Disease Control and Prevention.
