Expert says isolation has vital role in virus prevention

Virginio Bibang Ndong, from Equatorial Guinea, said China's efforts in prevention and control of the COVID-19 pandemic should be learned by other countries.

"I told my parents that I would not go back home in February when China reported an increased number of confirmed cases of COVID-19," he said.

Ndong, who arrived in China in 2014, is studying medicine at Southern Medical University in Guangzhou.

"I was very confident that China would tackle the problem in an efficient way, and I have now told my family members in Africa how to prevent themselves from being infected," he said.
