The Cornwall Regional Hospital in Montego Bay has intensified the process of relocating offices and clinics from a section of its facility which has been plagued by the re-emergence of noxious fumes.
Workers at the hospital have been falling ill since Friday.
RJR News understands that nurses, doctors and porters are among those calling in sick.
The fumes, which has been affecting the first, second and third floors of the hospital, is also creating discomfort for patients and visitors.
The first, second and third floors house the accident & emergency department, the main administrative block, the lab and the clinical area of the ten storey hospital.
Anthony Smikle, Chief Executive Officer of the hospital, said a directive has been given for the affected areas on the first to third floors to be relocated.
"We have started to relocate some of the clinic and some the diagnostic services departments. We also are relocating some of those on the compound and others we will relocate off the compound, within a close radius to the hospital because the services are critical to patient care delivery," he disclosed.
He said some diagnostic areas have already been relocated while clinics will begin their move this week.
A team from the Pan American Health Organisation, as well as local experts were recently called in to try to identify the cause of the smell however, they were unable to do so.
Meanwhile, the Nurses Association of Jamaica (NAJ) will be visiting its members at the Cornwall Regional Hospital this week.
NAJ President Janet Coore-Farr, said the organisation has received reports of nurses and other members of staff experiencing discomfort and have called in sick due to the noxious fumes.
Mrs Coore-Far said she will visit the hospital on Thursday to get a firsthand look at what is taking place as well as to provide support for members of the association.
