An unvaccinated California elementary school teacher has infected at least 26 people, including 18 students, with Covid-19, according to a study released by U.S. health officials on Friday.
This incident shows the importance of vaccinating school staff, especially when students are too young to receive the vaccine, according to the Centers for Disease Control and Prevention (CDC).
The incident also underlines the importance of taking preventive measures, such as the correct wearing of masks, in light of the intensifying epidemic due to the outbreak of the highly contagious Delta mutant.
The teacher continued to work in May 2021, two days after experiencing symptoms, believing he was suffering from an allergy. And he did not put on the mask more than once in class, despite the recommendations in force in the Marin district in the suburbs of San Francisco.
A total of 12 students in his class were infected, including eight who were seated in the front seats. The infection also caught six students from another class, due to “interactions between students at school,” according to the study’s authors.
They were all under 12 and could not get the vaccine. I also counted eight other cases among the parents of students and their brothers.
The windows and doors of the school were open and the students wore masks.
Analyzes showed that they were all infected with the delta mutator, and no case required transport to the hospital.
At a press conference on Friday, CDC director Rochelle Walinsky regretted that “many schools” had not adopted measures such as imposing masks indoors for everyone. She said that “many injuries are usually recorded in schools that do not follow the recommendations.”
As many parents and caregivers express concern about the new school season in the country, Walinsky cited a second study, the results of which were released on Friday, to highlight the effectiveness of the recommendations.
A study in the Los Angeles area, the most populous area of the United States, showed that the rate of infections among children and adolescents in schools was 3 and 4 times lower than that recorded in the rest of the population of the region, at the peak of the epidemic in winter.
Authorities in this region are demanding that schools adopt a series of preventive measures, such as wearing masks and respecting social distancing.
