Silvestri responded to the “deniers”: “Wasn’t Covid seasonal?”.

Cases of “coronavirus” increase in several European countries (but not in the United States or Canada) in the middle of summer. And immediately the “seasonal deniers” start in fourth place with their fingers up (just like no-vax was left in fourth place after the first cases of vaccine clotting) because obviously asking some people to think calmly and without prejudice is like asking a wild boar to eat with a fork.” Virologist Guido Silvestri, a professor at Emory University in Atlanta, analyzes the rise in COVID-19 cases despite summer temperatures by looking at “what is happening, the things we know and don’t know, and above all to those to think, calmly, reasonable and above all something in a scientific way.”

In a Facebook post titled “But isn’t it said it’s a seasonal virus?” , this is the founding scientist’s first consideration of the social page “Pills of Optimism”: “The seasonal effect on respiratory viruses, including human coronaviruses, has been known for decades to anyone who knows the subject, and to deny it is foolish. How exactly does this effect include Sars-CoV- 2, especially the delta variant, highly transmissible, we don’t know (and we’ll see soon), but 2020 data on the ‘original’ virus suggests an important effect. Also remember that seasonality does not have a ‘white versus black’ effect, just as you don’t get infected. All smokers have lung cancer.”

The second reflection is that “the European reopening of April/May was followed by massive gatherings” and “massive transfers” between countries, “often associated with the ‘roving European football’ championship,” Silvestri notes, calling for a deeper study of the potential European impact on The trend of infection in the ancient continent.

The third point, “The effect of vaccines in separating SARS-CoV-2 cases from hospitalizations and deaths from Covid-19 seems quite clear – as noted by an Italian virologist established in the US – and that’s exactly what we expect the vaccines we use and the way we use them.” With it, and as we have mentioned in the past, we must continue to monitor this aspect very carefully, along with the occurrence of new infections and especially serious disease between vaccinated versus unvaccinated.”

Finally, “we keep in mind that some effects can add and/or cancel each other out in a very complex and difficult way to decipher – Silvestri highlights – on the one hand reopening and clustering and a ‘delta effect’ to drive an increase in cases, and on the other hand vaccines and seasonality that Pushing in the opposite direction. The net result of these effects, in terms of infections and/or deaths, could vary from country to country, and in no case will it be seen in the coming weeks.”
