The CDC’s recent decision urging everyone including K-12 schools to wear masks indoors to avoid the spread of Delta Variant was brought about by the rapidly increasing number of infections.
The CDC’s decision comes as a result of infection cases quadrupling in July. The number of cases increases from an average of 13,000 cases every day at the start of the month to 56,000 cases. CDC had to revise its guidance of wearing a mask as the highly transmissible delta variant has created a surge in infected cases.
CDC’s guidance says that fully vaccinated people can spread the delta variant. As a result as fully vaccinated and none vaccinated people who live in places where the coronavirus transmission is classified as high should all wear face masks when in public places. CDC called for universal mask-wearing in K-12 schools stating that masks should be worn by all staff members including teachers, visitors, and children. These guidelines are amongst others implemented for covid 19 prevention in K-12 schools. The CDC has also encouraged students to go back to personal schooling as not to endanger their selves. Though vaccination has been authorized for adolescents research for vaccinating children under 12 is still ongoing. The CDC has stated that only 30 percent of adolescents between ages 12 to 17 have been vaccinated.
Previous Guidelines Implemented by the CDC
The CDC announced on May 13 that fully vaccinated people did not need to wear face masks indoors or outdoors in most situations. This was a means set up by the Biden administration to motivate people into getting vaccinated at the times before the delta variant.
The CDC’s guidelines of may did not totally eliminate the need for face masks on vaccinated people. Vaccinated people were still required to put on face masks on planes, trains, and other public transport systems and still had to follow other local mandates.
Reasons the CDC changed its Guidelines
During the spring before the surge of the delta variant research had shown that vaccinated people were at low risk of infection, hospitalizations, and death. The odds of a vaccinated person transmitting the virus was thought at the time was thought to be low. With the delta variant in the picture, everything changed. The CDC states that the rapidly spreading delta variant that accounts for a large majority of new cases in the United States had greatly altered the equation.
Breakthrough infections in vaccinated people are still rare and unvaccinated people still represent the large majority of people in the united states. Although infections are still rare in vaccinated people new unpublished research shows that vaccinated people have a similar viral load as unvaccinated people. This means that they will still be able to spread the virus. The CDC has mentioned that the delta variant behaves very differently from other variations of the virus. This has lead to the CDC going back on its progress to ensure public safety
