Chinese officials are concerned that COVID-19 may spread further as migrants return to their jobs in cities or other provinces after a prolonged Lunar New Year holiday.
Anyone returning to Beijing must to go into quarantine for 14 days or risk punishment.
A total of 1,716 health care workers in China have contracted COVID-19 despite WHO's guidelines, so this weekend, a team of 12 global and WHO experts will arrive in China to meet with local medical professionals for a "joint mission".
France reports Europe's first death from new virus -- a Chinese tourist from Hubei province -- while WHO hails Beijing's efforts for having "bought the world time". It was unclear how authorities would enforce the measure.
Hubei province, where the outbreak is believed to have originated, now includes cases based on a physician's diagnosis before they have been confirmed by lab tests.
Patients "clinically diagnosed" through lung imaging are now included, in addition to those that have shown up positive after laboratory analysis.
The World Health Organization (WHO) said that China is running more than 80 trials to find treatment for the COVID-19.
More than 2,600 new cases were confirmed from a coronavirus outbreak in mainland China, health officials said on February 15, a day after people returning to the capital from holidays were ordered to quarantine themselves for 14 days.
"China has bought the world time". What we don't know though is how much of the asymptomatic cases are driving transmission. "We call on all governments, companies and news organisations to work with us to sound the appropriate level of alarm, without fanning the flames of hysteria". The latest country to confirm a COVID-19 case outside of China is Egypt.
"It's impossible to predict what direction this epidemic will take".
