- A new study looked at nearly 1,000 students, teachers and household contacts in 24 classrooms in Berlin, Germany in March 2021
- Six cases of COVID-19 were detected, of which two were among students, one among teachers and three among household members
- The students and teachers who got infected with the virus all studied in different schools
- Researchers say the findings suggest that infection levels in schools are low and closing schools ‘should be a last resort’ to control the pandemic
- This comes on the heels of an LA County study that found there is low Covid transmission in schools and few outbreaks.
A new study suggests that schools are not the main source of COVID-19 spread and do not lead to an increase in cases.
Researchers from the Institute of Tropical Medicine and International Health in Berlin looked at the results of COVID trials in dozens of classrooms between February 2021 and March 2021.
They found that only two students and one teacher tested positive, even as the alpha version that originated in the UK was gaining dominance in Germany.
The team says the findings suggest that clusters of COVID-19 infections are not common in schools and that cases are often isolated in classrooms.
The new study adds to a growing body of research showing that classes are not linked to frequent outbreaks and that students and teachers do not test positive more often than the general population.

One study found that six cases of COVID-19 were detected, two among students, one among teachers and three among household members (above). The virus-infected students and teachers all studied in different schools
for the study published on Tuesday jama network open, the team looked at 24 school classrooms – 12 primary and 12 secondary – across Berlin.
Out of 898 participants, 263 were students and 112 were teachers. The remaining 523 were members of the household of students or staff.
In Germany, in mid-February after cases of COVID-19 increased, the country imposed a lockdown and schools were closed.
In March 2021, schools were again opened to in-person instruction, but many adopted a split class-model, with attendance on alternate weeks being half the size of the original class.
Researchers looked at COVID-19 cases during the lockdown and two to three weeks after classes resumed.
In Germany (above) some Covid cases were also detected in schools in the form of daily infections, which the researchers say lead to low levels of infection in schools
During the lockdown, the team found that only one symptomatic adult member of the household tested positive for the virus.
During this time no student or teacher was confirmed to have the virus.
Four weeks later, in March 2021, students returned to schools, but with mitigation measures, including three feet between desks, increased ventilation and frequent wearing of masks.
Six of the tested participants had confirmed infections: two students, one teacher and three household members.
Not only this, students and teachers who fell ill with COVID-19 went to different schools.
New data from the L.A. County Department of Public Health shows 1.5 million, or 0.5%, of a total of 7,995 students and 1,193 employees out of 157,000, or 0.7%, have tested positive for COVID-19, which officials say is a factor in this. there is evidence. Covid transmission in schools is low
Researchers say these cases were discovered when the alpha version was spreading rapidly across Germany, indicating that schools are relatively safe even during the boom.
‘In early 2021, we detected only isolated SARS-CoV-2 infections, no clusters, and a school attendance with one infection,’ the authors wrote.
‘This low level of infection in schools confirms our previous data. Our data supports that school closures should be the last resort to control the SARS-CoV-2 pandemic.
The study comes on the heels of a recent report good from the Los Angeles County Department of Public Health (LADPH), which found that outbreaks of COVID-19 in schools are not common with some students and teachers testing positive – and a small number of close contacts contracting the virus.
Data published online found that, between August 15 and September 13, a total of 7,995 students and 1,193 staff tested positive for COVID-19.
With more than 1.5 million students and 175,000 employees in county schools, that means 0.5 percent of children and 0.7 percent of workers have contracted the virus since the schools reopened.
Additionally, a very small percentage of children have tested positive after coming into contact with infected persons.
According to LADPH, more than 30,000 students and staff were forced to quarantine for seven days after they came in contact with a patient.
However, only 63 of them tested positive themselves, which is equivalent to 0.2 per cent.
LADPH health officials say COVID-19 protocols followed by schools may be the reason for the low numbers, which include indoor masking and universal testing by the Los Angeles Unified School District.
