The Chinese authorities announced yesterday that people infected with the Corona virus who came from a hotspot in northeast China were behind the transmission of the epidemic in five provinces, including the capital, Beijing.
China was largely able to eradicate the epidemic thanks to the imposition of masks and measures to isolate and track contact with the infected.
No deaths have been recorded since mid-May.
However, in recent months, new spots of limited injuries have appeared in various regions of the country, which have caused concern. China announced 68 new infections within 24 hours, the highest daily high since mid-April.
Among them, 57 were counted in northwest China's Xingyang District. And the rise in cases is also affecting for several days Urumqi, where millions of residents are being examined.
Six new cases were recorded in Dalian, the coastal city of Liaoning Province. A hot spot was detected last week at a local seafood processing plant.
The city of six million is one of two cities hosting the China Football League which resumed at the end of the week, and with the additional cases announced yesterday, it is now recording a total of 44 patients.
What constitutes an additional concern is that this focus contributed to the spread of the virus in five provinces, including Fujian, which is more than 1,200 km away, as announced by the health authorities.
The rise of cases in Dalian has also had repercussions for Beijing, where a person was declared infected with "Covid-19" in connection with a person carrying the virus, but without showing symptoms of the disease, he came from the coastal city.
It is the first domestic case registered in the capital since the epidemic was eliminated in early July.
Faced with this danger, the Dalian authorities announced extensive population checks, and said they had taken 1.68 million samples.
