According to an internal document from the US Centers for Disease Control and Prevention (CDC), the Delta variant spreads just as much as chickenpox, and complete vaccination hardly reduces transmission of the virus. Delta can also cause a much more severe COVID-19 mileage than previous variants.
- The Delta variant is already dominant in most countries. In the United States, it is responsible for almost 90 percent. illnesses. In Poland, it is over 60 percent.
- It is considered the most dangerous of all known variants of the coronavirus
- The latest figures from the US CDC say its R0, or reproduction ratio, is 8-9. That’s four times more than the original Wuhan coronavirus variant and twice as much as the Alpha strain

Delta variant very contagious, even despite vaccinations
An unpublished CDC document that was leaked to the media shows data that fully vaccinated people can spread the Delta variant as much as unvaccinated people.
CDC director Dr. Rochelle Walensky confirmed the authenticity of the document in an interview with the American media. – It’s a serious matter. This is one of the most infectious viruses we know about. At the level of measles or chicken pox, she told CNN.
Walensky spoke a few days ago about changing the guidelines for fully vaccinated people. She recommended that those who took both doses of the vaccine also wear masks in rooms and places where transmission of the virus is high. In her opinion, in schools, everyone – employees, students and visitors – should wear masks at all times.
“An extreme situation requires extreme measures,” she explained.

Delta variant like chicken pox
The CDC report says the Delta variant is as infectious as chickenpox. Each infected person infects eight or nine others on average. The primary variant of the coronavirus was transmitted like a common cold, an infected person transmitting the virus to an average of two other people.
The strength of the spread of viruses is indicated by the R0 index, or the reproduction rate. “There are really few diseases with an R0 of eight or nine,” Walensky told CNN.
The CDC report shows that in the case of vaccinated people, this rate is slightly lower than in the case of unvaccinated people. However, it must be emphasized that vaccinated people are protected against the disease itself.
- The Delta variant of the coronavirus is highly contagious, but far from the record holder
«Vaccines in over 90 percent. protect against the severe course of COVID-19, but may be less effective at preventing infection or transmission. That is why, despite vaccinations, more cases of disease occur and it spreads faster »- reads the report. Vaccines with the Delta variant reduce the risk of serious illness and death by a factor of ten, while the risk of infection by three times is reduced.
The data in the presentation also shows that the Delta variant can cause more severe disease than previously known strains.
In the United States, there were over 70 jobs in the last day. illnesses a day. For comparison, the average on June 22 is 11 thousand. 299 cases of coronavirus.
“The number of cases we have now is much higher than last summer,” Walensky told CNN.
Since Wednesday, the average number of cases over the past seven days has increased in all but one state.

The CDC document urges to further increase awareness that vaccination is the best defense against the Delta variant. The US administration has already taken steps in this regard. President Joe Biden announced a series of new regulations designed to vaccinate as many citizens as possible. Introduced, among others vaccination compulsory for all federal employees
– It’s an American tragedy. People are dying, and those who do not have to die will. Watch the news. You’ll see stories of unvaccinated patients in hospitals who, as they die from COVID-19, ask for a vaccine. Doctors then answer: I’m sorry, it’s too late, Biden said recently.
