Dayrit said the victims, one of whom is still in coma, could have suffered from "acute disseminated encephalomyelitis" with a final diagnosis of a systemic viral infection.
He cited the preliminary investigation report of the Department of Healths National Epidemiology Center which has sent a team of experts to Ormoc.
Instead of the West Nile fever virus, Dayrit said they are eyeing the Japanese B encephalitis virus which, he added, exhibits the same symptoms as the former such as sore eyes, high fever and tonsillitis.
But he said the victims must undergo an "etiology test" to really identify what virus afflicted them.
Dayrit allayed fears of Ormoc folk on the possible spread of the strange virus.
He said the DOH-NEC team has checked the situation at the Larrazabals MR compound in Barangay Bantigue in Ormoc, and has ruled out such an event.
Only four of the Larrazabal children were brought to the family-owned Cebu Doctors Hospital. Except for Marcos Larrazabal II, who is still in coma, the three kids, along with the rest of the victims, were declared out of danger.
Dr. Potenciano Larrazabal, the hospitals chairman and the victims grandfather, said laboratory tests showed that they were indeed afflicted by a virus.
But he said he and three other doctors were at a loss and could not identify the virus. With Freeman News Service
