Besides the dozen students in the teacher’s class, 10 other students at the school also later tested positive for the coronavirus.įour of them had siblings in the infected teacher’s class and were likely exposed to the virus at home, according to the report. In all, 27 coronavirus cases were identified in this outbreak, including the teacher. At the time of the outbreak, 72 per cent of eligible people had been fully vaccinated in the city where the school is located, according to the report. The outbreak’s effect on the broader community may have been limited by Marin County’s high vaccination rate, one of the best in California. “Strict adherence to … masking, routine testing, facility ventilation and staying home when symptomatic are important to ensure safe in-person learning in schools.” “New evidence of the delta variant’s high transmissibility, even among fully vaccinated persons, supports recommendations for universal masking in schools,” the authors wrote. The scientists who wrote the report said the results show why it is so important that universal masking inside schools is widely recommended in California, masking is required in indoor school settings. “The outbreak’s attack rate highlights the delta variant’s increased transmissibility and potential for rapid spread, especially in unvaccinated populations such as schoolchildren too young for vaccination.” “This outbreak of COVID-19 that originated with an unvaccinated teacher highlights the importance of vaccinating school staff members who are in close indoor contact with children ineligible for vaccination,” the authors of the report wrote. No one identified in the outbreak required hospitalisation.
Vaccinated parents in the outbreak experienced symptoms including fever, chills, cough, headache and loss of smell. Of the infected parents, one was unvaccinated, while three were vaccinated. The teacher’s students began falling ill on May 22.įour parents of children in the class were later infected in the outbreak.
The teacher informed the school on May 23 that the test was positive and self-isolated for a week. Nonetheless, the teacher continued working for two more days until May 21, the same day the teacher went to get tested for the coronavirus, the report said. The teacher at some point began coughing, suffered a headache and seemed to experience symptoms of fever. The teacher started feeling symptoms on May 19 of nasal congestion and fatigue and attributed them to allergies, according to the report written by experts from the University of California, Berkeley, University of California, Davis and University of California, Santa Cruz. The teacher reportedly read aloud to students while unmasked, despite rules requiring teachers to be masked indoors. A minority of those sitting at the back of the class were infected. Most of the students sitting closest to the front of the class were infected. The detailed report showed that a dozen children were infected with COVID after the teacher read a story unmasked. Among the teacher’s 24 students, 22 were tested and 12 tested positive for the Delta variant of the coronavirus, according to the report, written by county health officials and experts. The teacher was one of only two staff members at the school in Marin County, San Francisco, who had not been vaccinated. San Francisco: An unvaccinated, unmasked California primary school teacher who came to school even while visibly sick infected a dozen students with the coronavirus, all too young to be immunised, according to a report published by the US Centres for Disease Control and Prevention.
