Face mask social distancing Nasal stick tests: Those unwanted coronavirus control measures are far from the end for K-12 children returning to school after summer break.
It is unlikely that the COVID-19 vaccine It will be available for children under 12 years old before school starts in the fall. But a new study finds that when elementary and middle school children cover up and maintain distance between school days A single infected child tends to infect less than one student on average. The 30-day course
But if schools stop using masks Abandon efforts to reduce pediatric mix-ups. And it can’t detect and isolate those who may be infected. An outbreak can certainly happen.
However, such outbreaks are not necessary. And it gave the school board and local mayors a difficult choice.
If they are reluctant to admit to the relatively small number of student infections. They may have to consider taking potentially unpopular measures. This includes attending mixed classes/online learning. Strict isolation measures for classmates of infected students and continuous use of face masks .
The researchers found that over 2,000 runs in their primary elementary school. using a relaxed approach to masking social distancing and separation A single infected child is on average 1.7 likely to spread the coronavirus to other children over a 30-day period.
That might seem like an extreme case for eliminating some of the most tricky public health measures in elementary schools. But it didn’t take into account the key components of the sampling that the model revealed about 8% of the time. Five or more children were infected by only one infected student over a 30-day period.
That’s still a minor outbreak. with a relatively small possibility But it felt very real with the family involved.
and in high school returning to class The risk is even greater when measures to reduce coronavirus transmission are inadequate. This is largely because older teens appear to be spreading and getting sick from the coronavirus at rates that are closer to adults than younger ones.
When there are students on campus 5 days a week and easing social distancing and cloaking measures. An outbreak of a single high school student could expose 23 to 75 additional infections among fellow students, employees or classmates’ families over the course of a month. Weekly tests can reduce the number of endpoint infections to five. during the same period
Importantly, the model did not consider the effect of vaccination among persons aged 12 to 17 years. The COVID-19 vaccine produced by Pfizer and BioNTech has been authorized for use in children aged 16 and 17 from December and for those who Aged 12 to 12 years 15 from May
The new findings were published Monday in the Annals of Internal Medicine. They arise from a detailed “representative” computer model in which quasi-persons among students, students, school staff and students’ families interacted under established rules that dictated their behavior and infection.
The model captures the range of outcomes that occur when large numbers of people interact under different rules. Therefore, it is especially useful to weigh the relative effectiveness of policy measures that will change the way people interact.
Researchers from the University of Maryland and Harvard’s School of Public Health created a model of an elementary school in which 638 children from 432 households participated. 30 teachers and administrators attended the students to assess how face-to-face teaching would be under. different participation rules
High schools are larger and student movements are more complex. in such form A total of 1,451 students from 1,223 families rotate through eight classrooms every day. 63 teachers teach these students and gather in staff rooms as well. and 60 other school staff gathered with students in and out of the classroom.
There are several types of experimental classes: full-time, one-on-one attendance by everyone. Organizing students in schools into “groups” with limited interaction. Halve the class size. and have half of the students come to campus twice a week. The other half came in person for two days and everyone worked online three days a week.
The researchers simulated these scenarios thousands of times under different circumstances: with high, medium, or low “relief” measures, with and without testing for asymptomatic infections. and different levels of isolation for students who tested positive and their classmates who were infected.
Dr. Ted Long, Executive Director of the New York City COVID-19 Test & Trace Corps. wrote an editorial accompanying the study: The findings underscore that the risk of bringing students back to university is small while the benefits are high.
“The evidence is clear: our schools can safely reopen,” Long wrote, noting that about 40% of U.S. schoolchildren have not been invited to return to their classrooms since the pandemic caused school closures across the country.
“If schools can reopen one-on-one learning Those schools must,” he added. “To avoid the mental health problems and the educational crisis that lies before us.”
The study comes as COVID-19 among school-age children has become the focus of growing concern.
A new report released by the Centers for Disease Control and Prevention makes clear the rate of hospital admissions among teenagers from COVID-19. It was nearly three times higher than the number of hospitalizations with flu in a typical flu season. Moreover, 31% of adolescents aged 12 to 17 are hospitalized for COVID-19. This spring had to be admitted to the intensive care unit. and almost 5% required a ventilator
Dr. Rochelle Walenski, Director of the CDC, made a deep call to the number.
Research results of the report “Consistently emphasizes the importance of preventive measures against COVID-19 among adolescents. This includes correct and consistent vaccinations and masks,” the authors write.
meanwhile Number of cases and deaths from COVID-19 The sharp increase among Brazilian children and adolescents has raised concerns that gamma variants This is the version of the coronavirus that was first detected and is now spreading widely in Brazil. May affect children more severely than other breeds.
Gamma variants accounted for 7% of genetically sequenced coronavirus samples in the United States in the two weeks ending May 8, and it’s been linked to higher transmission rates and some ability to avoid consequences. Affected by the treatment of COVID-19 .
