In the United States, new data showed that a delta mutant of the corona virus is spreading faster than previously known, and even has the potential to infect restaurants with the vaccine.

Data collected by the Centers for Disease Control and Prevention (CDC) said that Delta mutants can cause serious injuries to people who have not received the vaccine, to a greater extent than all known mutants, such as alpha and beta, the Washington Journal reported.

The newspaper reported that it had seen data that was part of an internal report by American centers, showing that Delta is so highly contagious that it parallels the smallpox virus, which is highly known as its enemy.

The mutant was first detected in India in December 202, and earlier medical reports said that the portability of "Delta" was about 40-60 percent higher than that of Corona.

Although the report did not mention the new ratio, it was likely to be very large.

The report called on government officials to recognize that "war has changed" given the gravity of the mutant.

Referring to Delta, data from a district in Massachusetts showed an outbreak of new mutants there, which penetrate the bodies of vaccinated people with a similar viral load to those who were not vaccinated.

Viral pregnancy is a scientific term that reflects the amount of virus within the human body.

Although the Government document did not give figures, the Centers for Disease Control later revealed and after the report leaked further details about the Delta outbreak in the Massachusetts district.

American centers said that during the Independence Day holiday in Cape Cod County, a delta outbreak infected 469 people, although the majority (74 percent) were vaccinated.

The Centers for Disease Control and Prevention (CDC) states that Delta is more widespread than other versions of the corona virus, and other viruses such as smallpox and Ebola.

Although vaccines approved in the United States prevent more than 90 percent of severe infections, the characteristics of a dangerous mutant make them relatively less effective in preventing infection and transmission.

In an interview with CNN, the Director of the Centers for Disease Control and Prevention, Rochelle Wallinski, said that people should understand that we do not share false information, so Delta mutants are one of the most transmitted and infected viruses known.

More rigorous action was needed to counter the serious outbreak of mutant even among fed people.

Details of the report were leaked simultaneously. The Centers for Disease Control and Prevention changed recommendations for precautionary action.

This includes re-imposing the wearing of masks even for pollinators in indoor settings, regardless of their vaccination status, especially in areas where the virus is "highly or highly transmitted."
