Unidentified fumes sent three people to the hospital Wednesday and caused offices at the Elaineco building in Contant to be evacuated.
Workers and patients at the Maternal and Child Health office at the building known as the new AQ building suddenly began coughing, sneezing and even choking around 9 a.m.
Reportedly no strange odors were identified.
Two workers and one patient were sent to the hospital and all of the staff went for toxic screenings, according to the Independent and Daily News.
Laura Hassell, director of environmental health, said people also experienced irritation of the throat and chest pains.
The incident was investigated by officials from Planning and Natural Resources, environmental health, V.I. Fire Services,
Emergency Medical Services and the Police Department, but the source of the fumes has not been determined.
Hassell said while she is able to do a plate count to determine the density of bacteria in the air, there is no equipment available in the territory to test for chemicals.
