BEIJING — China has shared with more than 100 countries its experience in the prevention and control of the novel coronavirus disease (COVID-19) epidemic as the world witnesses a growing number of infected cases of the disease, a Chinese epidemiology expert said on March 24.

Chinese experience underlines the core effect of separation between the source of infection and the susceptible population, Wu Zunyou, an epidemiology expert at the Chinese Center for Disease Control and Prevention, told a press conference.

"China's epidemic control work mainly focuses on three aspects, tight control of the infection source, breaking the chain of transmission and protecting the susceptible population," said Wu.

Timely detection, reporting, quarantine and medical treatment have contributed to effectively reducing the source of infection in China, said Wu.

To cut off the transmission chain, Wu stressed the importance of wearing face masks, washing hands and ensuring ventilation.

China prolonged holidays and advocates keeping a certain distance between people for the good of the susceptible population, he said.

Many countries have adopted those methods in light of their conditions, Wu added.
