The samples are stored at the Wuhan Blood Center, and are estimated to arrive by 2019, providing real-time tissue samples from a large Chinese population area where SARS-CoV-2 is thought to have started infecting people.
Blood bank specimens were kept for two years, Chinese officials said, if required as evidence in any of the blood-related courts.
The two-year waiting period will soon end in a special month of October and November 2019, when many experts think the virus could first infect people. A senior official from the China National Health Commission, told CNN to prepare for the upcoming trial, and confirmed the tests would take place when the two-year limit was reached.
“This brings us very close to the ground we have seen of real-time samples to help us understand the timing of this event,” said Yanzhong Huang, chief medical officer at the international health council’s foreign relations council.
They “absolutely will have value,” said Maureen Miller, associate professor of medicine at Columbia University. He urged China to allow foreign experts to observe the process. “No one will believe China’s conclusions unless there are qualified observers,” he said.
The head of the Chinese research team, Liang Wannian, said in a July news conference that China would test samples, adding that if Chinese experts “get the results, they will give them to both Chinese and foreign experts. Teams.”
Liang said the samples came from a blood pump opening, which was closed and stored, and Chinese experts “conducted several surveys of the test methods and action plan, which will be performed after the end of the two-year limit.
The samples, if properly stored, may contain important indications of the first human inventions to fight the disease, experts said.
Liang stated in July that although the first reported case was in Wuhan on December 8, “our research with ancient Chinese research papers shows in full … December 8 may not be the first case. There may have been other cases before.”
Dr. William Schaffner, from the Vanderbilt University Department of Medicine’s infectious disease unit, said the samples provided “an interesting opportunity. You need to come back to feel exactly what months the virus began to leave its toes in China.”
The samples could even indicate who was first infected, where, and their age and occupation, Miller added.
“It’s common to see samples,” he said. “So you can take it away from the population, age, community of men where they live. All of this data will be available.”
Schaffner said the samples could be brought to Geneva, or another neutral location, to allow WHO experts to take part in the experiment.
He said two things that could happen with samples could be “the reliability of blood samples – making sure they weren’t made in the recent past,” but also how the population representatives like all blood donors were. “Miller said most of the samples were probably taken from healthy people” so they represent asymptomatic cases. And as we have learned from this epidemic, asymptomatic cases exacerbate this epidemic. “
Huang said it was unclear how “the outside world could rely on what was found to be true or satisfactory,” and the experiment showed China’s opportunity to “tell the world that they are determined to undermine the first regime.”
Leaders in Biden conducted a 90-day intensive study on how the virus originated, however an unconfirmed report had officials still examining natural transmission from animals to humans and the laboratory dropping as a practical theory, but unable to determine which one was a possibility.
President Joe Biden, receiving the sample, said: “Important information about the origins of the epidemic exists in the People’s Republic of China, but from the beginning, Chinese authorities have worked to prevent foreign researchers and members of the international community from accessing it.”
