Beijing reports new Covid-19 case as Northeastern outbreak spreads to nine cities
Beijing reported one new local Covid-19 case Tuesday, its first in 21 days, as infections linked to the latest flare-up in Northeast China have spread to nine cities around the country.
The 53-year-old Beijing patient had dined with an asymptomatic carrier who was previously in the Liaoning province port city of Dalian, where 44 cases have been reported since last week, the capital’s health commission reported (link in Chinese). The pair met in Jinzhou, another Liaoning city.
Cases linked to the Dalian outbreak, which is thought to have originated with a seafood importer, have been detected in cities in five provincial-level regions, including the southern province of Fujian and as far north as Jilin and Heilongjiang provinces, Zhao Lian, deputy director of Beijing’s health authority, said Tuesday.

Dalian, a port city of 6.7 million people in Liaoning province, has recorded 44 Covid-19 infections since Wednesday after months of near-zero daily rises.
According to announcements by municipal authorities, more than 70% of the sickened people either work at the same seafood company or are related to those who do.
Dalian government officials said at a Thursday press conference that multiple food and environmental samples collected from the factory’s refrigerated goods, processing areas, staff dormitories and dining areas had tested positive for the virus.
It remains unclear how the facility was contaminated. Officials are exploring two main theories: either that the virus was introduced into the factory by an infected person, or that it spread to workers from contaminated seafood products imported from overseas.
According to government notices, officials at Dalian customs found traces on July 3 of the coronavirus in a sample taken from the inside of a container used to import frozen shrimp from Ecuador.
Scientists do not think SARS-CoV-2, the virus that causes Covid-19, can infect much marine life. In April, researchers affiliated with the United Nations and the Chinese Academy of Fishery Sciences published an article in the journal Asian Fisheries Science saying there was “no evidence” that fish, crustaceans, mollusks or amphibians could contract the virus and pass it to humans.
Zhu Hua, a virus expert at Hong Kong University, told Caixin that many viruses can remain infectious in subzero temperatures.
“The virus samples we use in the laboratory, which are stored in a liquid nitrogen environment at minus 80 degrees [Celsius], might live for decades,” Zhu said. “Even at minus 30 degrees, they can live for a few years.”
