As the COVID-19 pandemic continues to spread to many parts of the world, governments are desperately seeking to balance the desire to involve the spread of the virus with the social and economic burden of physical distance measurements and closures in schools and workplaces. recently published on the medRxiv prepress server in September 2020 through researcher Richard Beesley of Juvenile Arthritis Research reports that they have an effect on the reopening of schools on the spread of the virus.
At the beginning of the pandemic, in many countries, schools and schools closed their doors to prevent the transmission of Coronavirus 2 of Severe Acute Respiratory Syndrome (SARS-CoV-2). Since then, some governments have had legal reopenings. The objective of this study is to know the threat posed by the reopening of schools in terms of viral spread and increased number of cases.
Researchers downloaded the number of new instances according to day and country to calculate cellular totals for seven days per day, matching numbers to compensate for independent points such as excessive variability in the degree of capacity at which verification centers operate on other days. of the week.
All countries in this survey had a total of seven days or more of new cases in a day or more since the registered onset of the pandemic in their countries. The daily life threshold for cases excluded the option that trends are inadvertently masked. Included countries had one or more transparent waves or peaks, but without a first wave in progress When other regions adhere to independent schooling systems and dates, unified national knowledge is not available, as in the United States, and those countries have also been excluded again, if variability is considerable, the knowledge collection is likely to be of poor quality and also an exclusion criterion.
The investigation drew a map of the reopening policy and the time of the closure and reopening of schools in general cases, for either outcome: a construction or no construction in cases.
They discovered 4 models:
In the first case, schools closed but did not reopen, and the total number of instances is not a thing in the opening of schools. The countries with this trend are divided into two categories, those that have an upward trend and those that they still have a low number of instances.
In Ireland, Italy and Turkey, for example, cases are higher, while schools have remained closed, due to comfort and visiting criteria and the increased number of holidays. Five other countries have had a strong set of cases, perhaps because other restrictions are still in place. Site.
B. was the position in which schools closed and re-opened before or when instances increased. This applies to Egypt, Portugal and Romania, and the result is to mask the effect of reopening schools.
In 3rd or category C, reopening is positioned after a minimization in the initial number of instances, and two subcategories were identified: one in which instances are being built and one with an even low number of instances. , with an accumulation in cases after the initial peak that occurred on average 37 days after the reopening date. The current category includes only China, which has vigorously implemented widespread testing, case detection, isolation and closure of schools where an epidemic is feared.
The cause of an increase in the number of reopening-like instances is likely due to more than one cause, as there is a heterogeneous trend of increase, which is accompanied by easing and tourist restrictions, especially when it allows visitors from other countries with superior COVID-19 occurrence. Other points come with the return of parents to the office when schools reopen, the return of young people to the custody of other members of the circle of family members other than their own parents, and increased use of department stores and other recreational facilities.
However, reopening schools is probably one of the contributing factors, as the increase in the number of instances exceeds the expected convenience-only constraints. The number of cases was higher, as in Canada, Singapore and the United Kingdom.
Where those limits are still in place, the number remains low.
D. The last style, in which schools remained open at all times. This was noted with Sweden, where, according to the researchers, “the country’s politicians announced that keeping schools open did not lead to an accumulation in the instances. “that Swedish schools closed during the summer on 9 June, and 23 days later, the total number of instances over seven days began to decline, which is consistent with findings from other countries where the accumulation of instances followed the reopening of schools approximately the same period of time, which raises abundant doubts as to the clinical basis of their earlier claim.
The knowledge implies that the accumulation in the cases in all the countries where the schools have reopened is greater than in the places where they remain closed. to the reopening of schools, however, the latter is a contributor.
English schools opened two weeks later than those in Scotland and Northern Ireland. During this short period, outbreaks began in 53 schools, involving 106 academics and teachers, with another 18,000 people quarantined. This casts a dark shadow over attempts to reopen in the UK, which has limited the ventilation and spacing of pupils in classrooms, greater when masks are not mandatory or are not even allowed.
Lack of concentration in the transmission of formites and symptomatic patients ignore the importance of aerosol transmission and asymptomatic propagation. Such futile attempts at containment make it inevitable that viral spread will occur even more after school reopens in countries that refuse to focus on controlling viral spread through restrictions. face-to-face and face-to-face meetings, as well as contact tracking and testing quickly. Fix and isolation when the transmission is thought to have occurred.
The study concludes: “Although the reopening of schools after an initial peak and a minimize reduction of COVID-19 infections is desirable for a variety of reasons, doing so without sufficiently good controls and protections would possibly lead to an exacerbation of spread in environmental school, which can also lead to further spread of the disease in the community. “
medRxiv publishes initial clinical reports that are not peer-reviewed, and therefore should not be considered conclusive, the consultant’s clinical practice / health-related habit, or treated as established information.
