A Chinese official has warned that the epidemiological situation in the Chinese capital is "very serious" at a time when more than 8 million people infected with the emerging coronavirus around the world, more than half of them in Europe and the United States.

Zhu Hejian, a spokesman for the Beijing mayor, told reporters on Tuesday that the city was "racing against time" against the virus.

The municipality spokesman added that the capital "must take the most firm and strict measures."

And the city - which has a population of 21 million people - raised the number of tests it conducted to detect the virus, to more than 90 thousand tests per day.

While the renewed epidemic raises fears of a "second wave", the World Health Organization announced on Monday that it is "closely" following the situation in Beijing, speaking about the possibility of sending additional experts in the coming days.

On Tuesday morning, Beijing announced 27 new infections in the past 24 hours, taking the total number of cases recorded five days ago to 106.

The outbreak began in the wholesale food market of ChinaVade, one of the largest in Asia, where the virus was detected last week.

Since then, four other markets in the capital have been closed, in whole or in part, and quarantined about 30 neighboring residential areas.

Primary and secondary school students can now resume lessons from home.

Quarantine in other cities
And in the rest of China, cities have announced that expatriates from the capital are being quarantined.

A Shanghai city official said today that the authorities have decided to place all comers to the city from moderate to severe areas in relation to Covid-19 for a period of 14 days.

The resurgence of infections comes at a time when the country, in which the Covid-19 epidemic appeared for the first time at the end of last year, was able to eradicate the disease in practice in recent months.

According to official figures, China has counted 83,221 injuries, including 4,634 deaths. No deaths were announced a month ago.
