According to the Health Service Executive (HSE), up to 12,000 children are out of school as a result of being close contacts.
The policies that surround close contacts appear to be having a negative effect on the reopening of schools as about 1,200 schools have now identified a case among students.
An additional several thousand students are off classes after contracting the disease or because they tested positive for the virus.
Current policy prevents close contacts from resuming school until they receive a negative PCR test ten days after being designated as a close contact.
Across the country, there have been close contacts reported in approximately 700 primary schools and 500 secondary schools.
The figure may rise as it only reflects cases from last week when some schools had yet to reopen or were not running at full schedule.
Approximately 1,200 children have been infected with the virus while 2,800 contracted the virus but have not yet resumed school.
