• Increase of Covid cases in Italy.

    Long queues, and many hours of waiting, at the drive-in to swab

  • Coronavirus: 4,458 new cases in 24 hours, 22 deaths, over 128 thousand swabs carried out

08 October 2020 "Today, with the new 4,458 cases of SARS-CoV-2 infection (albeit with contained mortality and hospital situation under control), many are experiencing moments of anxiety, sometimes unfortunately accentuated by a communication that tends to confuse the (right) recommendation of (due) caution with cues of distressing (and counterproductive) alarmism ", writes on Facebook the virologist Guido Silvestri who however urges" everyone to be optimistic and remember the Science that is coming to the rescue of humanity scourged by the pandemic ".



Fifty-seven years old, born in Perugia, Silvestri explains the three important areas of progress that could help defend us from the Covid-19 coronavirus: "

The first area is that of vaccines

, in which eight promising candidates are in phase-3 of clinical trials, with various platforms (inactivated virus, adenoviral vectors and messenger RNA) and excellent preliminary results from both preclinical animal studies and phase 1 and 2 clinical studies. It is now a matter of months, if not weeks, before programs begin mass vaccination (which seems to be already underway in China and Russia). It should be remembered that these platforms were developed especially in previous research efforts for vaccines against AIDS, tuberculosis, hepatitis, malaria, flu, which has enormously accelerated the their application for Covid-19. The

second area is that of genetic studies

which, using technologies of great "throughput" (Hospital services and treated patients,

ed

) s developed to study cellular DNA in the context of other diseases, they have now made it possible to discover gene variants significantly associated with severe SARS-CoV-2 disease. These studies are important to define clinical risk markers in patients with COVID-19 to be used to "personalize" therapy and understand if the high lethality of the first wave has contributed to the infection of highly susceptible subjects for genetic reasons. The

third area is the development of neutralizing monoclonal antibodies

against SARS-CoV-2. Here, Trump's rapid improvement after administering the Regeneron cocktail created an "acceleration" of development, with companies Regeneron and Lilly announcing super-promising results of interim phase-3 studies of their products, with reduction of the risk of hospital admission if administered at the time of the positive swab between 72% and 85% (which should correspond to a similar if not greater reduction in lethality) ".



" All to reiterate - concludes Silvestri - while we prepare to face these last months of forced coexistence with the virus, which is now really numbered ".
