China News Service, Beijing, August 31 (Reporter Guo Chaokai) A number of international experts jointly issued a paper to put forward the priorities of the next stage of the new crown traceability research. Chinese Foreign Ministry spokesperson Wang Wenbin said at a regular press conference on the 31st that traceability should be based on With a global perspective, the future traceability work will not be limited to a certain region, it needs to be carried out in multiple countries.
A reporter asked a question. Recently, more than 10 international experts from the China-WHO Joint Expert Group published an article in the journal Nature and proposed that the priorities of the next stage of traceability research include searching for the early stage in all areas within and outside China where evidence of the earliest transmission of the virus appears. Cases and antibody investigations on unreported cases within and outside China.
What is China's comment?
"We agree with the views of relevant international experts you mentioned." Wang Wenbin said that China has always advocated that scientific evidence should be used as a guide to effectively carry out international cooperation in scientific traceability, and jointly carry out the next stage of traceability research in many countries and places around the world.
In March this year, experts from China and the WHO released a joint research report on the traceability of the new crown virus, which also clearly pointed out that traceability should be based on a global perspective.
Wang Wenbin said that as scientists from various countries continue to study the new coronavirus, a number of experimental studies have shown that the emergence of the new coronavirus in many places around the world is earlier than the previously known time.
He further pointed out that public news showed that on September 12, 2019, the urine samples of Italian measles patients were found to be positive for the new coronavirus nucleic acid, and the sequencing results have been uploaded to the public database; in November 2019, an Italian woman's skin biopsy found multiple locations for the new coronavirus In situ hybridization reactivity; the genetic material of the new coronavirus was detected in wastewater samples collected in Florianopolis, Brazil on November 27, 2019; December 13, 2019-January 17, 2020, United States Archived samples from routine blood donations in 9 states tested positive for new coronavirus antibodies; the prevalence of neutralizing antibodies in France increased in mid-December 2019; a throat swab sample from a hemoptysis patient in France was tested for new coronavirus RNA in December 2019 Positive; a wastewater sample collected in Barcelona, Spain, in January 2020, tested positive for the new coronavirus nucleic acid; from January 2 to March 18, 2020, there were 24,079 blood samples from 50 states in the United States, and the new coronavirus antibody was detected in 9 samples ; Of the 624 white-tailed deer blood samples collected in multiple states in the northeastern United States from 2019 to March 2021, 1 in 2019, 3 in 2020, and 152 in 2021 were positive for new coronavirus antibodies and were infected None of the white-tailed deer showed signs of illness.
“There are still many such examples, which fully demonstrate that it is necessary to trace the source of the new crown epidemic in multiple locations and multiple locations. The traceability work to be carried out in the future must pay full attention to this.” Wang Wenbin said that China has been following the recommendations in the joint research report without interruption. China is carrying out domestic traceability research. China hopes that countries that have found earlier evidence can act as soon as possible. Like China, it invites WHO experts to carry out scientific research on the ground and work together to solve the mystery of the source of the new crown virus.
