The Medical Officer of Well being (MOH) of the regional division of public well being declared the prevalence of a SARS-CoV-2 outbreak on the college and ensured that each one associated circumstances had been documented within the Computerized Infectious Illness Reporting System (CIDR ).

They’ve additionally alerted the Nationwide Well being Safety Surveillance Middle of Eire. Companies had standardized the administration of COVID-19 outbreaks in these settings nationwide.

They referred all COVID-19 circumstances discovered to be infectious whereas attending college to regional “College Groups” for a Public Well being Threat Evaluation (PHRA), which assigned them a novel college identification quantity.

As soon as an infectious case working in a faculty was recognized, together with these with signs and even asymptomatic, these officers suggested them to self-isolate for seven to 10 days, relying on suggestions on the time.

In addition they recognized shut contacts, i.e. individuals who had direct contact with a confirmed case by the PHRA course of. They thought of an individual to be a detailed contact once they had been involved for greater than quarter-hour with a confirmed case on a faculty day whereas self-reporting their adherence to IPC measures, equivalent to face masking.

As soon as recognized, they barred these people from college for 14 days and offered them with sufficient public well being recommendation and testing info.

In addition they prioritized COVID-19 testing pathways for college students and employees in 2020-2021. They counted all shut contacts who examined constructive for SARS-CoV-2 as secondary circumstances. Shut contacts may solely return to high school after testing adverse on RT-PCR and turning into asymptomatic.

Eire additionally had a nationwide COVID-19 Contact Administration Program (CMP), a web-based info system, that helped hint the contacts of all RT-PCR confirmed COVID-19 circumstances.

Contact tracers have used this method to contact folks with confirmed COVID-19 to find out whether or not they attended college throughout their infectious time and to establish their shut contacts.

The crew carried out statistical analyzes of all obtainable knowledge on the nationwide COVID-19 contact administration program from week 19 of 2021. Be aware that these knowledge don’t characterize notified circumstances of COVID-19 which have undergone knowledge validation procedures by the CIDR system.

The researchers expressed categorical variables as percentages, estimating variations between teams utilizing a chi-squared check and contemplating p<0.05 to be statistically vital.


In response to knowledge from the CIDR system, 832 college outbreaks occurred between August 2020 and June 2021.

The examine findings revealed that college outbreaks in Eire had been usually small, with 34% of all such outbreaks involving two and 92% involving fewer than 10 circumstances. Surprisingly, lower than 3% of shut contacts of COVID-19 circumstances in class settings examined constructive.

The authors famous 21,727 RT-PCR confirmed circumstances of COVID-19 amongst youngsters aged 5 to 18 in Eire throughout the three phrases of the 2020-21 tutorial 12 months. Solely 2.4% of all youngsters aged 5 to 18 in Eire had COVID-19, representing 18.2% of the entire reported COVID-19 circumstances in Eire, or 119,640.

In comparison with folks with COVID-19 between March 2020 and July 2021 throughout all age teams in Eire, these aged 5-18 accounted for simply 13.3% of all circumstances. Nevertheless, these case numbers amongst youngsters aged 5-18 elevated over the three quarters of the 2020-21 tutorial 12 months, from 15.5% of 58,148 circumstances within the first quarter to 17.5% of 31,069 circumstances and to 23.9% of 30,423 circumstances in two and three time period, respectively.

It additionally helped them establish 90.5% (n = 90,953) of scholars and 9.5% (n = 9,521) of employees had been shut contacts. These outcomes confirmed that main and particular college college students had a markedly increased COVID-19 positivity price than employees members (2.4% versus 1.8%).

Then again, college employees members had a barely increased COVID-19 positivity price in post-primary colleges (1.9% vs. 1.8%), however this transformation was statistically insignificant (p = 0 ,88).


The present examine favors worldwide proof exhibiting that instructional settings had been a low-risk setting for SARS-CoV-2 transmission provided that they applied acceptable IPC measures and adhered to requirements.

Subsequently, college closures should stay a final resort as a COVID-19 mitigation measure and all youngsters should be allowed to proceed their schooling with minimal pointless disruption.

In any future pandemic, colleges shouldn’t be closed earlier than fastidiously contemplating all of the adverse results and advantages of disruption to schooling.
