Three schools in Co Clare have closed after Ireland's first "cluster" instance of coronavirus was confirmed on Wednesday evening.

Three schools in Co Clare have closed after a family of four was confirmed to have coronavirus (Covid-19) on March 4. The family, who are now in isolation care, had recently been in northern Italy, which is experiencing a severe outbreak of the virus.

According to The Irish Times, a primary school and a secondary school are closed for two weeks until March 18th, while another secondary school is closed for one day pending advice from the Health Service Executive (HSE).

The primary school sent out a text to parents on Wednesday night confirming the two-week closure: “A child in our school has tested positive for Covid-19 and as a precaution, school is closed from tomorrow (Thursday) for 14 days. Re-opening 18th March. Public health doctors will contact you individually from tomorrow on."

Management at the secondary school also sent a text to parents overnight confirming the short-term cancelation: “(School) will remain closed Thurs 5th March pending advice from HSE re. Covid-19 (coronavirus) cases in locality. Will advise further tomorrow.”

Scoil Chaitriona in Dublin closed earlier this week when one of its students became the first person in the Republic of Ireland to be diagnosed with the virus.
