To prevent further spread of the Delta coronavirus variant, the US Centers for Disease Control and Prevention has updated its mask guidance on Tuesday to recommend that fully vaccinated people wear masks indoors when in areas with “substantial” or “high” transmission of Covid-19, which right now includes nearly two-thirds of all US counties.

CDC Director Dr. Rochelle Walensky told a media briefing on Tuesday, “In recent days I have seen new scientific data from recent outbreak investigations showing that the Delta variant behaves uniquely differently from past strains of the virus that cause Covid-19,”.

CDC also made the point that ams need to be work properly and cover the nose as pictured.

She added, “This new science is worrisome and unfortunately warrants an update to our recommendations,” and “This is not a decision that we or CDC has made lightly.”

A source involved with the decision process told CNN that new unpublished data shows that vaccinated people infected with the Delta variant can have as much virus in their nose as people who are unvaccinated, which is the primary driver for the CDC’s latest mask guidance change, with overall though, vaccinated people still play a small role in transmission and breakthrough infections remain rare.

The new guidance also recommends fully vaccinated people to test 3-5 days after a possible or known exposure, and to continue to wear a mask when in indoor public settings for the next 14 days or until a negative test result.

In addition, the new guidance also says that all people at a school, regardless of vaccination status, so staff, teachers, students and visitors, should all wear a mask.

The report says that it might not be the guidance that people were hoping to hear, but as advised throughout this pandemic, “We’re in this together…Remember to be kind, mask up, and get vaccinated when you can”.

In addition, another report from the USA says that Americans who refuse vaccinations are endangering millions of immunocompromised people

In an example the report says that all Kimberly Cooley wants to do is hug her 6-year-old nephews, but she can’t because tens of millions of Americans are choosing not to get vaccinated against Covid-19, adding that Cooley received two doses of Pfizer’s Covid-19 vaccine in February, but blood tests show the shots didn’t give her antibodies against the virus.

That’s because, like millions of Americans, Cooley takes medications to suppress her immune system, after she had a liver transplant in 2018 with a study by Johns Hopkins researchers published Monday found that vaccinated immunocompromised people like her are 485 times more likely to end up in the hospital or die from Covid-19 compared to the general population that is vaccinated.

Based on an estimate by the CDC, about 9 million Americans are immunocompromised, either because of diseases they have or medications they take and it has been known for months that Covid-19 vaccines might not work well for this group. The hope was that vaccination rates overall would be so high so that the “herd” would protect them.  But it didn’t work out that way, because about a third of eligible people in the US have not received even one dose of a Covid-19 vaccine.

A study published Monday in the journal Transplantation found fully vaccinated organ transplant recipients were 82 times more likely to get a breakthrough Covid-19 infection compared to the vaccinated general population, and 485 times more likely to be hospitalized or die from Covid-19.

Dr. Dorry Segev, a transplant surgeon at Johns Hopkins Medicine and lead author of the study said, “This is a stark reminder that there are many vulnerable people around us who have been unable to achieve the same levels of protection that the rest of us have been able to achieve, and as a result are at much higher risk of getting sick or dying from this terrible virus.”

The message is clear though, think of others, not just ourselves and do our civic duty mask up and get vaccinated.
