In the wake of their deaths, Calanog told KVUE the couple's bodies will remain on the island until it is determined that the illness is not infectious.
The Ministry of Health and Medical Services has ruled out influenza as the cause of the tragic deaths of U.S. tourists David Paul and his wife Michelle.
The Texas couple, Michelle and David Paul, arrived in Fiji around May 22, according to NBC News. Authorities say Michelle Paul, 35, died on May 25 at a clinic in Fiji and David Paul, a 38-year-old Air Force veteran, died in a hospital three days later.
She said the couple's remains can not be returned to the United States until a cause of death is determined.
The families of David and Michelle Paul said they couldn't believe it when authorities in Fiji called them, saying the two suddenly died, ABC News reported on June 4.
Her husband, David, died days later.
Authorities are continuing to investigate the deaths. "At this point, we are not aware of any specific public-health threat to the community".
The relative, Tracey Calanog, told WFAA the couple loved to travel and had been planning to go to the area for a while. After her passing, hospital staff reportedly planned to transfer David to an Australian hospital by helicopter for additional treatment but he died shortly before they could, according to KVUE.
The company says that it is working with the family to help bring the family back to Texas.
Family members believe that David and Michelle may have contracted a deadly virus, as the Fiji government had issued warnings about a unsafe flu season in the region.
