The
CDC recommended that everyone, including those who have been
fully vaccinated, wear a mask in public indoor settings in areas
with substantial and high transmission. The agency also
recommended universal indoor masking for all teachers, staff,
students, and visitors to K-12 schools, regardless of
vaccination status, according to a news release.
“While data continues to show the effectiveness of the three
COVID-19 vaccines currently authorized in the U.S., including
against the Delta variant, we are still seeing the virus rapidly
spread among the unvaccinated,” IDPH Director Dr. Ngozi Ezike
said in a statement. “Cases and hospitalizations due to COVID-19
both continue to increase, overwhelmingly among the
unvaccinated, but the risk is greater for everyone if we do not
stop the ongoing spread of the virus and the Delta variant. We
know masking can help prevent transmission of COVID-19 and its
variants. Until more people are vaccinated, we join CDC in
recommending everyone, regardless of vaccination status, wear a
mask indoors in areas of substantial and high transmissions, and
in K-12 schools.”
Areas of substantial transmission are considered by CDC to be
those with 50 to 99 cases per 100,000 people over a 7-day
period. Areas of high transmission are considered to be those
with more than 100 cases per 100,000 people over a 7-day period,
according to a news release.
