China: The Beijing Omicron infection related to a mail from Canada, and the Canadian Minister of Health: Unusual
On January 17, Beijing notified the traceability of confirmed cases of COVID-19 pneumonia in Haidian District, pointing out that the case self-reported that he had recently received an international email from Canada.
Combined with the epidemiological history of the case, the test results of samples of suspicious items, and the genetic sequencing results of the case specimens, the possibility of contracting the virus through foreign items cannot be ruled out.
Canadian Health Minister Jean-Yves Duclos said the statement was “unusual” when asked about it on the 17th local time.

Minister Canada: This view is ‘unusual’
The Canadian Global News Network video shows that Duclos said at a press conference on the 17th that important opinions must be based on information and expertise, “We all want to follow the opinions of experts in this regard, and I will ask the Canadian public. Experts from the health agency come to study the issue.”
When the reporter asked Duclos whether he did not rule out Canada Mail bringing Omicron into China, he said this was an “unusual” view, and re-emphasized, “I am not an expert, doctor or biologist, I will Get the right people to give the right advice and perspective.”
On January 17, the Beijing Municipal Government Information Office organized the 267th press conference on the prevention and control of the COVID-19 pneumonia in Beijing to introduce the traceability of the local epidemic.
Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention and a member of the national new coronavirus pneumonia expert group, introduced that the cases reported on January 15 had no history of travel and residence in other provinces and cities within 14 days before the onset of the disease ;
through the investigation of the cases, the contact history with various risk groups , no track overlap was found .
The case self-reported that he had recently sent and received international mail, “We have conducted a comprehensive investigation, sampling and testing.
The international mail was sent from Canada on January 7 and arrived in Beijing via the United States and Hong Kong, China, and the case was received on January 11. Mail.” The case stated that during this period, he only touched the outer surface of the mail package and the front page of the document paper, but did not touch the inner surface of the package and other papers.
22 environmental samples of the international mail have been collected, including 2 on the outer surface of the package, 2 on the inner surface and 8 on the paper inside the document.
The nucleic acid test was positive, and the specific mutation site of the Omicron variant was detected. .
Pang Xinghuo said that as of now, there are 8 people who may have been in contact with them during transportation, and the nucleic acid test results of the other contacts except the case are all negative.
In addition, 54 environmental samples of international mails from the same source and sent to another location that have not been opened were collected, and 5 were found to be positive, including 1 positive for the outer packaging and 4 positive for the paper in the document.
” Combined with the epidemiological history of the case, the test results of samples of suspicious items, and the genetic sequencing results of the case specimens, the possibility of contracting the virus through foreign items cannot be ruled out. “
Pang Xinghuo said that in the past, many provinces (cities) in some countries have also reported cases of transmission through cold chain or non-cold chain items.
Recently, there have also been reports of positive overseas mail and other items in many places in some countries.
She reminded that the new coronavirus can survive in low temperature for a long time, and the risk of transmission through objects increases in winter.
At present, the epidemic of COVID-19 pneumonia caused by the mutant strain of Omicron is high in the world.
Citizens should try to reduce the purchase of overseas goods during the period of high epidemic situation abroad.
If they receive overseas mail or items, they should wear masks and disposable gloves correctly to reduce direct contact and communication.
In addition to the recent confirmed cases in Beijing who have a history of contact with foreign objects, at a press conference held in Shenzhen on January 17, Lin Hancheng, a second-level inspector of the Municipal Health Commission, said that the first cases of the “0107” and “0115” epidemics in Shenzhen have recently appeared.
All have a history of contact with foreign objects. According to the comprehensive analysis of the results of the flow survey and virus traceability, the possibility of infection by overseas mail items cannot be ruled out.
At the Beijing prevention and control press conference held this afternoon (18th), Pang Xinghuo informed that from 0:00 on January 17 to 15:00 on January 18, Beijing added 2 new confirmed cases of local COVID-19 pneumonia and 1 positive nucleic acid By. She once again called on “less overseas shopping” to fulfill her personal responsibility for epidemic prevention and control.
Health Canada says likelihood ‘extremely low’
Regarding whether the new coronavirus can be transmitted through “human-to-human transmission”, the answers of various research institutions vary. In March 2020, the experimental results of a joint team of top international scientific research institutions such as the National Institutes of Health and the National Center for Immunization and Respiratory Diseases showed that under normal air humidity and temperature conditions, the new coronavirus can survive at least four on copper surfaces. hours, 24 hours on cardboard, and longer on polypropylene plastic and stainless steel surfaces, up to 72 hours. Some Australian research institutions also believe that the new coronavirus can survive on smooth surfaces such as banknotes and glass for 28 days.
According to Health Canada, the likelihood of coronavirus spreading through the mail is “extremely low.”
The Public Health Agency of Canada said in an email to the Canadian Broadcasting Corporation (CBC) that while mail may be contaminated, the risk of contracting the COVID-19 is extremely low when handling paper mail or cardboard packages, including international mail… We know that transmission of the virus is highest when people are in close contact with other people who have the virus. “
Gerald Evans, an infectious disease expert at Queen’s University in Canada, told the Global News Network that the new coronavirus will not survive long after it leaves the host.
He cited a study released last week by the University of Bristol in the United Kingdom that found that after the new coronavirus exhaled by an infected person enters the air, it loses 90% of its infectivity within 20 minutes, and most of the loss occurs within 5 minutes.
Colin Furness, an epidemiologist at the University of Toronto, said that although the survivability of the new coronavirus on paper depends on the roughness of the paper, it is unlikely that the virus will survive for more than a day or two.
China State Post Bureau: Effectively build a solid barrier for the prevention and control of the epidemic of international mail express
Since the discovery of the new coronavirus, people’s cognition has been constantly refreshed. In September and October 2020, there was a wave of COVID-19 epidemic in Qingdao.
At that time, Deputy Mayor of Qingdao, Luan Xin, introduced that Qingdao’s epidemic prevention and control work had found a sufficient chain of evidence for the first time in the world, indicating that the COVID-19 virus can be transmitted from person to person and frozen. conditions for long-term survival.
As for whether there is a risk of spreading the new coronavirus by international mail, Zhang Liubo, chief expert of disinfection at the Chinese Center for Disease Control and Prevention, said in an interview with reporter that the COVID-19 is still in a pandemic state internationally, and there is a risk of contamination in express delivery.
If the amount of pollution is relatively high, accompanied by saliva, sputum and other organic matter, and the external temperature is low, especially the northern hemisphere is currently in the cold winter season, the temperature during storage and transportation is low, and the temperature in the aircraft warehouse is also very low, which is conducive to the survival of the virus. , so it is possible for the virus to survive for seven days or even longer.
According to a CCTV News report on the 17th, the Department of Safety Supervision and Administration of the State Post Bureau has issued a notice a few days ago, pointing out that the current Spring Festival is approaching and the Beijing Winter Olympics is about to open. .
The notice requires that we further improve our ideological understanding, effectively build a barrier for the prevention and control of the epidemic situation of international mail and express, and strictly prevent the import of overseas epidemics through the delivery channel.
