A Fairfax County girl who was removed from kindergarten in November because she has AIDS will be allowed to return to school under medical supervision, the School Board announced yesterday.

Emerging from a 2 1/2-hour closed meeting, the board voted, 8 to 0 with two members absent, to accept Superintendent Robert R. Spillane's recommendation to readmit the child, under the condition that her medical condition be reviewed at least weekly.

Spillane previously had said it was unlikely that he would favor allowing a child with AIDS in a regular classroom.

In addition, the board said yesterday that the school system will ask the county Health Department to provide a registered nurse at the school while the child is attending.

"The superintendent and his staff have plans to make this transition back to school as smooth as possible, which includes working with school staff and community to prepare the child's return to the classroom," said board member Joy Korologos, who chaired the meeting.

No date has been announced for the child's return, although board members said they hoped it would be soon.

The girl's mother filed suit against the school system Dec. 22 charging that her daughter's ejection violated a federal law that prohibits discrimination against the handicapped. It was the first such lawsuit in the Washington area and one of only a handful around the nation.

Neither the girl nor her school has been identified.

A panel including a Health Department employe, a pediatric infectious-disease specialist and a school system employe will meet at least every three months to review the child's condition, the School Board said. If the girl's condition worsens, Spillane will have the authority to remove her from school until the board's next meeting, when it will act on his recommendation.

The two lawyers representing the girl's mother said they were pleased by the board's action and said the conditions set for the girl's return were acceptable.

"It's a shame they couldn't have acted rationally a month ago," said Frank Feibelman of Richmond. Lawyer Kenneth Labowitz of Alexandria said the action "is a good sign" for other families with AIDS-afflicted children.

A hearing on the mother's motion for a preliminary injunction, which was scheduled for Jan. 8 and requested that the child be allowed to return to school, will probably be canceled, Labowitz said.

Before heading into its closed meeting, the board defeated a motion by member Letty Fleetwood, from the Providence district, to add a personnel issue to its agenda.

The motion was not explained in public, but a source said it dealt with Spillane's conduct in calling a news conference on the girl's lawsuit the day it was filed before briefing the board about the case. Several board members have said they were unhappy about not having been kept up to date, and one said that the issue would be raised again.

At that news conference, Spillane said the lawsuit was premature because he had not yet received medical recommendations in the case. His comment to reporters after the news conference questioning the lawsuit touched off a controversy.

Yesterday's emergency meeting was called Thursday after county Health Director Richard K. Miller informed Spillane that he saw no medical reason the child should not be back in school under certain conditions.

The only facts about the child's condition that have been made public are that she is believed to have acquired AIDS from a blood transfusion shortly after birth and that she is being given AZT, the only drug approved for the treatment of AIDS.

Miller said Thursday that meetings were planned for Monday at the child's school to ease her return.

Some board members are concerned about possible parent backlash, "and that's one of the reasons for informing parents about the situation," said board member Anthony Cardinale. But he said, "I have no reservations {about admitting the child} based upon the medical report."

The board is scheduled to meet again Thursday to hear Spillane's recommendations for a policy spelling out how the school system will handle cases of students and teachers with AIDS. The board previously had resisted writing a policy, but reversed itself Dec. 26 -- four days after the filing of the lawsuit and Spillane's news conference -- and ordered the superintendent to draft one.

The county Council of PTAs has been urging the School Board to draft an AIDS policy for months, and the lack of a written policy was one of the issues in the lawsuit by the mother of the child with AIDS.

Federal and state health authorities say that most children with acquired immune deficiency syndrome can attend school without restriction. Only in cases where children bite, bleed or are unable to control bodily fluids should limitations be considered, according to medical authorities. Lawyers for the child said she is eligible for school with no limitations.

In barring the child from the classroom, Fairfax officials cited a Virginia law prohibiting students with communicable diseases from attending school.
