An internal report from the US CDC to which the New York Times had access, assures that the Delta variant of the SARS-CoV-2 coronavirus is as contagious as chickenpox, which in temperate countries has reached 90% of susceptible individuals before 20 years.
In addition, this report adds that vaccinated people transmit the Delta variant infection like unvaccinated people. And with the ability to spread serious disease.
We know that the Delta variant is much more contagious than the previous ones. But every new piece of news we hear about this strain is almost worse than the previous ones.
And experts are starting to say they see every day more likely that it could shatter the protections provided by vaccines. Plus, it can cause more serious illness than any other known version of the virus.
These are two new statements extracted by the prestigious newspaper The New York Times, from an internal presentation circulating within the CDC (Centers for Disease Control and Prevention).

The greatest danger is in the nose and throat, hence the masks
People infected with the Delta variant have about the same amount of virus in their nose and throat as those who are not vaccinated. And that means they can spread the virus just as easily and at the same risk to those around them.
But it doesn’t end there, since the internal document they are handling at the CDC presents a broader and much more worrying view.
Because he views Delta as more contagious than the viruses that cause MERS, SARS, Ebola, colds, seasonal flu, and smallpox. And as contagious as chickenpox, according to the document, a copy of which was obtained by The New York Times.
That is why, according to the report, and as the Washington Post announced Thursday evening, the immediate next step for the agency is to “recognize that the war has changed”.
All those who have had access to the document, which may be released today, assure that their slides perfectly reflect the alarm that exists among scientists about the spread of the Delta variant around the world.

They ask to act now!
Delta is a very serious threat and it is now. That is why we must act now. At the CDC, we are very concerned about the data coming in on the threat of this & rdquor; variant.
And while it is true that some scientists still maintain that transmission of the virus from vaccinated people is rare, many scientists now claim that it is much more common than previously thought.
This is the rationale that led the CDC to recommend the use of masks for those vaccinated. And in this report, they describe the need for its use as “essential”. Especially for people who are immunocompromised or those who, vaccinated or not, have close contact with young children, the elderly or vulnerable people.
Infection with the Delta variant produces amounts of virus in the airways ten times greater than those seen in people infected with the Alpha variant, which is also highly contagious, the document notes.
The amount of virus in a person infected with Delta is a thousand times greater than that seen in people infected with the original version of the virus, according to a recent study.

A real example & mldr;
The report echoes, among other things, a real-life case that occurred in a town in Massachusetts following the Independence Day festivities that took place on Sunday, July 4.
Well, on Thursday, just 4 days later, there were already 882 cases of the coronavirus. And officials say 74% have been vaccinated.
A fact that infectious disease scientists have described as “one of the most impressive examples of citizen science we have seen”.
Bad news and good news
As with so many things in life, it is possible to find bad news and good news around the same event.
In this specific case, the harm could be very bad, and this forces us to raise the system of protection, individual precautions and impose the necessary limitations on ourselves.
Because in this report, we are already starting to say that infection with the Delta variant is more likely to lead to serious illness than with the other variants known to date.
Additionally, studies in Canada and Scotland have found that people infected with the variant are more likely to be hospitalized, while other research, conducted in Singapore, has indicated that people infected with Delta are more likely. to need oxygen.
But the good news, and very important, is that with the numbers the CDC manages, it is still possible to defend with data that vaccines are very effective in preventing contagion from ending in serious illness, hospitalizations and deaths.
This is what prestigious virologist John Moore says:
“Overall, Delta is the disturbing variant we already knew it was, but the heavens don’t fall on us and the vaccination still strongly protects against the worst outcomes.”
