Port Quimie Junior Secondary School in south Epi cancelled all classes last week after some of its female students began behaving strangely.
The school principal Charley Tari told the paper the girls behaved in strange ways as if sick or possessed by spirits.
Mr Tari said all of the affected students have been sent home.
He said classes had resumed but many in the school were still fearful because it was not the first time it had happened.
