COVID-19, from WHO a report, the published one, with really interesting content.  The report concerns the geographical origins, the way the coronavirus is spread and lays the foundations for a mapping project that could, in the future, avoid the repetition of certain dynamics.

COVID-19, WHO: it is not sure that the coronavirus originated in Wuhan, China

This statement had already been launched a few months ago by an Oxford professor at the prestigious British broadcaster BBC.

But the formal recognition of this hypothesis by the world’s leading body in the field of health care significantly changes the thickness of the same.

The assumptions adopted by the WHO to justify the statement are essentially two:

• The first concerns the remarkable genetic stability of the virus, identical in large tracts of its genome in the various strains, to indicate its suitability to affect the human organism, perhaps remaining silent for a long time. This is confirmed by the analysis of wastewater from some places in the world, which demonstrates the presence of the virus before December 2019 in Wuhan.
  –
• The second is its propensity to use vector hosts, intermediate organisms: the famous bat of Wuhan has gone down in history, but things are not exactly like that.

The studies collected by the WHO, collecting organisms of all the world case reports, have shown that SARS-CoV-2 is in fact present in many other animal species and that with them humans can give rise to various forms of zoonosis.

COVID-19, WHO: at least 500 animal species are infected or can be infected by the coronavirus

Some examples cited by the World Health Organization report are cats, many forms of non-human primates, pangolins (they are anteaters), shrews, tigers and lions (in the USA), ferrets, the famous minks (in Denmark a slaughterhouse), shrimps and salmon.

There are more than 500 animal species that can act as intermediate organisms in the passage of the coronavirus to humans, based on ACE receptors suitable for COVID-19.

Although emphasizes the WHO report, there is no evidence of food transition from animal food to humans.

The WHO report clearly states that it is not possible to demonstrate a food-borne zoonosis, while studies from various places in the world have clearly shown that surface contamination is at the basis of the zoonosis.

Let’s take a concrete example.

You are in front of your lunch. A salmon or steak reminds you that you are hungry, and that dish is the solution to your appetite.

The WHO report states that there is no evidence at all that food will infect you.

It says, however, that it is absolutely proven that the sink on which you placed the steak will be contaminated, the shopping bag in which you placed it, the supermarket counter in which it was placed, the counter of the wholesaler who delivered it to the supermarket, the market area that the wholesaler went to, the slaughterhouse that the market turned to, and so on back to the breeder of the animal that then generated the meat from that steak.

The theme then is the attention to hygiene.

Understanding the origins and inserting them into a precise picture is the real objective of the WHO report: “while the pandemic continues to develop – says the incipit, which you find in full form at the end of the article – it is essential to understand how the epidemic began to prevent further introduction of SARS-CoV-2 viruses and help prevent the introduction of new viruses in the future.

It could also potentially contribute to the development of treatments and vaccines (Zhang Z. et al. 2020).

Identifying the origin of the virus, however, is a complex task that requires strong international and multi-sectoral collaboration, and a commitment to harness skills, expertise, and work globally”.
