Who are the people with natural immunity to David-19?

After a year of pandemic and millions of infected people still stand in the shadows of those who seem to be immune to the Sars Cov2 virus.

Valerie Fabbret of Alessandro Antonini, a married couple from Tern but who live in Milan, are an example. He got sick a year ago but thought it was a cold while she was standing by to take care of him without being infected. The confirmation comes several months after the serial test.

How can some individuals ' ability to resist infection be explained? It is still early to say scientifically, although scientists who are studying these cases already have an idea. “When there is a pandemic, the factors in the game are pathogens, host and the environment where infection” develops -feather Giuseppe Novelli, polyglinika geneticist hor Vergata's in Rome and president of Milan's Giovanni Laurenzin Foundation.

We're focusing on the second one that's essential. In the first few months of infection, we have found that there are astompotics, average cases and serious cases. But if the virus is the same then it's obvious that the host makes the difference. This happens all the time, with all of the” infections.- He cuts.

A team of scientists at the Toor Vergata, along with a group of more than 250 labs worldwide, have been co-ordinated by New York's Ruckfeller University and trying to find an explanation. We're studying Human DNA and statistical connection based on age and gender. We first focused on the gravely ill and have found that there is a 1012 % of cases that have a particular genetic characteristic. They fail to produce the first molecule of protection. On the basis of this experience, we've asked if there's a genetic difference in what we've called "resistant," so the people who, when they co-exist with a subject that is positive, not only don't get sick but don't get infected at all. The serious effect on infection has a number of risk factors. “We have found at least 50 genes that today give more or less the tendency of the disease. But that is not enough because to be scientifically confirmed, it has to be proved clinically.

We need to see if these genes have a weight in this matter” is Novell. To achieve accurate scientific results explaining why some people are immune to the virus, many studies must be done, especially on what are considered special cases, such as those of the Tern couple. Novell explains that a selection process has been launched in order to draw a scientific conclusion that will serve not only this pandemic but also the future. It's not easy to figure out if there are people who are really immune to the virus, based only on a test for Ovidius. As Roberto Luzhat, professor of infectious diseases at the University of Trieste, points out, <x1 ->munity is not provided solely by antibodies. It also exemplifies the so - called cell immunity”. Blood cells are needed to be studied.
