In Beijing, a confirmed infection with the Omiljun strain originated in an international mail from Canada, which, through public information, we know is actually an express mail: a thick paper bag containing several pages of paper documents. On the inside and outside of the message, as well as on the surface of the contents of the paper, the viral nucleic acid test is positive.
The No. 17 case in Shenzhen announced by the Shenzhen Center for Disease Control and Prevention on the 17th contacted and spun off the courier from North America on January 12, and did not disclose the contents of the express delivery, nor did it disclose the nucleic acid test results on the surface of the contents of the express delivery.
Since we have never encountered an infection of mail from person to person before, both Beijing and Shenzhen have carefully expressed the judgment as: "The possibility of infecting the virus through overseas items is not ruled out."
This is the profession, this is the science, and when there is a phenomenon that subverts our original cognition, it represents the possibility rather than the so-called real hammer.
On January 17, local time, when the Canadian health minister was asked "Do you not rule out the possibility that Canadian mail will introduce Omikeron into China", Duclo replied that this statement is "unusual". He added, "I'm not an expert, a doctor or a biologist, and I'll let the professionals give the right advice and perspective." ”
This is an equally scientific and deliberate answer, starting with the fact that the question subverts the usual canadian perception that the mail-borne virus was once recognized as a very low probability event. The Mainland State Post Bureau once announced in 2020 that the transmission of the virus in mail is a very low probability event, and the public can receive mail with confidence. So, the health minister used "unusual" expressions of surprise to hand over "correct advice and opinions" to "professionals".
Obviously, in the face of this problem that may change the process of sending and receiving mail on a global scale, whether it is Canada, which is not lightly affected, or China, which is the beginning of the Omicron, or any country on the planet where there is international mail exchange, it should only be left to professionals and science.
In fact, from a scientific point of view, this problem is not difficult to solve.
The scientific method is: simulation experiments.
The packaging used in daily international mail is readily available, and there is no shortage of mail contents such as paper, and the strain of Omilon is now available for China: there are confirmed cases of the Omiljun strain in several provinces and places, and it should not be a problem to design several simulated international mail containing active viruses, and then simulate the delivery environment and detect viral activity at multiple time points. This is an experiment that is easy to design and implement.
Through experiments, we can know: the survival time of the Omiljung strain on the surface of a variety of mail and the surface of different contents, we can know the impact of the original mail disinfection method on the virus activity, we can determine whether a new disinfection method is needed, the safe time for international mail reception, and importantly, it is reasonable to confirm yes or no when the virus is traced.
In the absence of scientific trials in this area, it may not be enough to say that it is possible, because to prevent the spread of the epidemic, this current "possible" channel does not allow "possibility" and needs to be clarified as soon as possible.
Some domestic public opinion has already said that this is poisoning or sabotage, and that people's responses are careless or careless, but in fact, they are all unfounded false assertions. The real basis must and can only come from science, and it is much easier to prove this than to study vaccines or drugs against viruses.
Under the general situation of the global epidemic, it is necessary to rely more on science, rely on scientists, spit on the mouth, and only spread the virus.
Do the real thing, don't talk nonsense.
