“実質的で高い透過率のある地域, CDCは、完全に予防接種を受けた個人が、デルタの拡散を防ぎ、他の人を保護するために、公共の屋内環境でマスクを着用することを推奨しています。,” the agency wrote ahead of a briefing. Though rare, breakthrough infections do occur in fully vaccinated individuals, しかしながら, unvaccinated populations account for nearly all current hospitalizations and recent deaths.
In a significant shift from prior guidance, the health agency also recommended “universal indoor masking for all teachers, スタッフ, 学生, and visitors to K-12 schools, regardless of vaccination status.”
“最近では, I have seen new scientific data from sequenced outbreak investigations showing that the delta variant behaves uniquely differently from past strains of the virus that cause COVID-19,” CDCディレクター博士. Rochelle Walensky told reporters over a call. “Information on the delta variant from several states and other countries indicate that in rare occasions, some vaccinated people infected with the delta variant after vaccination may be contagious and spread the virus to others.”
“This new science is worrisome and unfortunately warrants an update to our recommendations,” Walensky said.
Walensky sidestepped whether the new guidance would remove incentive for some parents to seek vaccines for kids.
The CDC previously advised masks be worn indoors by all individuals ages 2 and older not fully vaccinated against コロナウイルス. The CDC previously stated that those who are fully vaccinated didn’t need to wear a mask or physically distance in any setting, including while participating in extracurricular activities or while eating. しかしながら, it noted that based on the needs of the community, a school may opt to make mask use universally required regardless of vaccination status.
The CDC urged those not yet vaccinated, and eligible to receive a COVID-19 vaccine, to do so, 書き込み: “Unvaccinated individuals should get vaccinated and continue masking until they are fully vaccinated. With the Delta variant, this is more urgent than ever. The highest spread of cases and severe outcomes is happening in places with low vaccination rates and among unvaccinated people.”
