State health and environmental officials say testing at Pines Elementary in Plymouth has not determined what might have caused dozens of kids to get sick.
School will remain closed Thursday while the investigation continues. State health department officials said Wednesday that lab results from samples taken at Pines Tuesday did not indicate any relationship to the kids getting sick. Investigators will survey staff and parents of the sick children to better their exact illness. In the meantime, carpets and air returns in the school are being cleaned.
Monday six children were sent to the emergency room, complaining of coughing, general respiratory distress and vomiting. This came five days after some 30 students began coughing and complaining of headaches.
The school outside of Plymouth was shut down Thursday and school officials thought they had corrected the problem later that day. Students returned Friday and no problems were reported.
Wednesday the state took swabs from air conditioning vents, walls and carpet. Those samples will be sent to Raleigh for further testing.
Experts say they concentrated on the schools "A" wing where the symptoms were most prevalent. The state looked at temperature, humidity, air supplies, volume of air, and carbon dioxide.
The team also looked at overall moisture levels and found nothing unusual. They also checked temperature and humidity levels in several places and say everything was with design parameters and within acceptable limits.
The school system says as soon as written reports are available, they will be made available to the parents and the public.
