As schools across the country began to open for the new school year, an American teacher read aloud to students without wearing a mask. This is a warning story.
In May, an unvaccinated teacher at an elementary school in Marin County, California, read aloud to her students after taking off the mask, even though the school requires everyone to wear a mask indoors.
According to a report from the US Centers for Disease Control and Prevention, the teacher developed symptoms on May 19. She continued to work for two days before being tested for COVID-19 on May 21. The teacher tested positive for the delta variant.
On May 23, the school began to receive COVID-19 case reports from students, parents, teachers, and school-related staff. The Marin County Public Health Department conducted contact tracing, including whole-genome sequencing.
The CDC report stated that 26 cases were found to be related to the teacher, including her 12 students. The report stated that in her classroom, the “attack rate” of the two rows of students closest to her was 80%, and that of the last three rows was 28%.
A student in another classroom also tested positive for the coronavirus. All students in both classes are too young to be eligible for the COVID-19 vaccine.
At the same time, England’s National Bureau of Statistics stated that the country’s coronavirus infection rate this year was 26 times that of the same period last year. Officials warned that the upcoming opening of schools and universities may lead to an increase in the number of cases.
On Sunday, the Indian Ministry of Health reported 45,083 new COVID-19 cases in the past 24 hours.
According to the Johns Hopkins Coronavirus Resource Center, there are more than 32 million COVID cases in India. Johns Hopkins University reported that only the United States has more, with 38.7 million cases, and the United States has reported 49,712 new cases in the past 24 hours.
