Does the mouth have a role in its transmission? Study explains why crown is highly contagious

The new Corona virus continues to baffle scientists day in and day out, due to its strange nature, symptoms and details.

A group of pathology researchers, dentists and otolaryngologists from the medical faculty of the University of São Paulo in Brazil reported that the novelty is able to multiply in the salivary glands, which has opened a new door to new possibilities.

Why is Corona so contagious?

In details, the research was published in The Journal of Pathology, and one of the authors of the article, Bruno Fernandez Matuk, explained that until now, it was believed that the viruses that cause common diseases are those that use the salivary glands as reservoirs, so research may help explain why the virus is highly contagious.

As for the study, according to which the scientists analyzed samples of 3 types of salivary glands, namely, the “parotid, submandibular and small” of adult patients who died from “Covid-19”, and concluded that the tissues responsible for the production and secretion of saliva are like reservoirs for infection.

The researchers also noted that, using an electron microscope, not only the presence of the pathogen, but also its reproduction in cells.

Does the mouth have a role?

It should be noted that scientists had previously identified “ACE2” receptors in the ducts of the salivary glands, to which the viral protein “SARS-COV-2” that causes Covid-19 disease binds, turning it into a gateway to the disease. ‘infection.

It has also been previously shown that in addition to ACE2, there are at least two receptors present in the salivary glands, namely (membrane-associated serine proteases) and furin, which act as targets for pathogen.

Although the infection is now believed to enter the body primarily through the nose, scientists will use new research to test whether the mouth can be a direct entry route for the virus.

painful threshold

It should be noted that the Covid-19 epidemic has killed more than 4 million people, as announced last Wednesday by the Director General of the World Health Organization, Tedros Adhanom Ghebreyesus, adding that the real toll is certainly higher than that, he said. .

“We have crossed the painful threshold of four million deaths from Covid-19, which is certainly a lower death toll,” Ghebreyesus said at a press conference.

Globally, the organization has recorded 183 million cases of infection since the start of the pandemic.
