COVID-19 Schools Infection Survey, England - Office for National Statistics
• Since March 2020, 1.0% of primary school-aged pupils and 2.7% of secondary school-aged pupils met the Delphi criteria for having experienced long COVID lasting at least 12 weeks.
• “Loss of taste or smell” was the only symptom group where the prevalence was significantly higher for those who had received a positive coronavirus (COVID-19) test since March 2020 than those who hadn’t, for both primary and secondary school-aged pupils aged under 16 years.
• Both primary and secondary school pupils who tested positive for COVID-19 showed no significant difference in the number presenting with a “probable mental disorder” compared with those without a positive test.
• Primary school pupils with long COVID (under the Delphi criteria) were significantly more likely to have a probable mental disorder (30.0%) than those without long COVID (7.7%); the trend was similar for secondary school pupils (22.6% compared with 13.6%), but this is not statistically significant.
