Hidden sets between embedded points to climb the delta

They were gold miners in French Guiana, Cape Code revelers, and health workers in India. Even though the world lived apart, they had two things in common in the end. All were vaccinated against covid-19. And they all became part of the set of infections.

In recent weeks, such cases have been proving that covid-19 transmission chains and excessive expansion events can also occur. almost all groups are vaccinated, to raise alarms among health officials and torpedo hopes to return to business as usual in the US.

In May 2021, the CDC told embedded Americans that they could go into hiding, but on Tuesday the agency reversed its course, saying inserted people should wear masks in indoor public spaces.

The reason was learned by researchers from an appearance in the coastal town of Cape Cod in Provincetown, Massachusetts, with a noisy parade in early July and crowded weeks of pool parties. Since then, health researchers say there have been more than 800 cases of kobid-19 associated with these events, 74% of which were in people who were vaccinated.

The appearance in Provincetown was caused by the so-called delta variant, which now covers most of the U.S. cases. In document released todayCDC chief Rochelle Walensky said the “key finding” is that vaccines infected with the Provincetown delta contain as many viruses as those that do not have a virus in their systems.

“High viral loads increase the risk of suggestion and raise concerns, unlike other variants, that delta-infected vaccines can transmit the virus,” he said.

The recommendation suggests a return to the layers of opposing measures, including masks and social exclusion, which could also make it difficult to reopen the school next month in the US.

Infection in a gold mine

Research around the world has revealed outbreaks of vaccines in recent weeks. For example, a scientific team from Paris and French Guiana recently described how covid-19 breached a South American gold mine in May, even though almost all miners received the Pfizer vaccine.

Despite being inoculated, 60% were infected with a variant called gamma. This surprised the scientists so much that they checked to see if the vaccines were damaged in the shipment, but they were not.
