Norway wants to resume salmon sales after China all-clear

Ryan said he "fully expects" China to publish the genetic sequencing of the virus from the Beijing outbreak as it has done in the past.

"The risk of the epidemic spreading is very high, so we should take resolute and decisive measures", Xu Hejian, a spokesperson for the Beijing city government, said at a news briefing on Monday, the Guardian reported.

From June 11 to 16, Beijing reported 137 domestically transmitted COVID-19 cases, most of which were related to the now-closed Xinfadi wholesale farm produce market in the city's Fengtai District.

Chinese authorities say the virus may have originated from overseas, and they're suggesting it may have come via imported salmon.

The city's anti-epidemic measures had relaxed in recent weeks after the annual meeting of China's parliament in May saw thousands of delegates flock to the capital. There is also no blanket curb on residential compounds. "There can only be so many cases around us now if there were already many people with no symptoms or light symptoms back then". So far, the city has 27 areas designated as medium-risk and another area - close to Xinfadi - marked as high-risk.

Provinces have begun screening people from Beijing, while health authorities have barred those considered medium- and high-risk from leaving the city.

Online classes have been resumed and students are not allowed to return to school from Wednesday.

On Monday, the Beijing Hospitals Authority selected 100 medics including 24 doctors, 62 nurses and 14 staff from clinical labs and radiology departments, to aid the treatment at Beijing Ditan Hospital.

"Many people have become careless, frustrated with wearing masks", he said.

State-run newspapers reported that the virus was discovered on chopping boards used for imported salmon at Beijing's Xinfadi market amid worries about a second wave of the pandemic in China.

Not long after declaring itself virus-free, New Zealand detected a re-emergence of the virus.

The limited number of cases meant Beijing did not yet need to deploy a citywide emergency response and could instead make targeted adjustments in certain areas, he said.

Until the new outbreak, most of China's recent cases were nationals returning from overseas as COVID-19 spread globally, and the government had all but declared victory against the disease. Beijing, with the capacity to test more than 90,000 people daily, tested more than 70,000 Sunday alone, city authorities said.
