Protective measures such as contact tracing and quick isolation of cases COVID-19 (New Coronavirus Infection) According to an Australian survey, it could be the key to safely reopening US schools in September of this year.
The study, which included thousands of schools and kindergartens, determined that a total of 27 children and teachers were in school while infected with the new coronavirus.
However, thanks to proper social distance, hand washing and contact tracing, the infection has spread to only 18 out of thousands of school populations, said a team led by Dr. Kristine Macartney, a pediatrician at the University of Sydney. She directs the National Center for Immunization Research and Surveillance in Australia.
“Our findings are the most comprehensive data ever. SARS-CoV-2 infection in schools and early childhood education. ” Lancet Child & Adolcent Health..The findings were published in the journal on August 3rd.
In the United States, the debate about the safety and wisdom of reopening schools is intensifying.As part of that, with the US Centers for Disease Control and Prevention Prevention As long as certain precautions are taken, the resumption should be safe and beneficial to the child’s academic and social well-being.
The agency’s new guidelines are based on the idea that children do not spread the disease as easily as adults and that infection with the new coronavirus usually does not cause much disease.
Unlike many countries, Australia has decided to allow schools to remain open even during an ongoing coronavirus pandemic.
Macartney and her group scrutinized data on the health of students and staff in more than 3,100 schools and 4,600 kindergartens in New South Wales.They tracked the health of people who were in school during the first date COVID-19 (New Coronavirus Infection) A case diagnosed by the end of the semester (April 10) in New South Wales (January 25).
Overall, only 27 people (12 children and 15 adults) attended school during the infection, according to the team. Potentially dangerous infections occurred in 15 schools and 10 kindergartens.
However, once identified, contact tracing was quickly introduced to identify and quarantine people who could help spread. SARS-CoV-2.
Close contact with a known infected person was “defined as people with a minimum of 15 or 40 minutes of face-to-face interaction with the infected person in an indoor space,” the researchers said.
Close contact with approximately 1,500 of the 27 infected individuals was followed by telephone and instructed to take a test if symptoms occurred.
About 44% of these contacts did You will be tested after showing symptoms that may show signs COVID-19 (New Coronavirus Infection)However, researchers pointed out that only 1.2% of these close contacts were tested positive for infection.
Overall, they did not appear to be effective carriers of the virus, they added.
“We found that the child-to-child transmission rate was 0.3% and the child-to-staff transmission rate was 1.0%,” Macartney and colleagues said. “Staff-to-child transmission was 1.5% and staff-to-staff transmission was 4.4%, suggesting that children are less likely to spread the virus than adults.”
And of the total population of 1.8 million children in New South Wales, 98 are known to be infected with the new coronavirus, which accounts for only 3.2% of the total. Was there. COVID-19 (New Coronavirus Infection) In the case of the state. This confirms that “the incidence of disease in this age group is low,” the study authors said.
The Macartney group emphasized that the investigation was flawed. For example, I could only track it. COVID-19 (New Coronavirus Infection) The proportion of patients who show signs of illness and the proportion of asymptomatic or very mild cases that may still play a role remains unknown. The study was also done relatively early. COVID-19 (New Coronavirus Infection) Pandemic, they said.
Dr. Ameshua Dalha is an infectious disease expert and senior scholar at the Johns Hopkins Health and Security Center in Baltimore. Reading the new report, he said, “These studies show that schools are part of the community and that community communication affects schools.
“As schools reopen, I believe it is a priority action, but it will be important to make plans to mitigate the unavoidable effects of the virus,” Adalja continued. “But if the location cannot be strongly planned and is located in an uncontrolled expansive area within the community, they will cause great confusion due to the virus.”
