Health officials in Fiji say they don't yet know the cause of the sudden deaths of a Texas couple holidaying on the island but have ruled out influenza .
David Paul, 38 and Michelle Paul, 35 died within two days of each other after falling ill from an unknown ailment.
Their two young children had been left with relatives at home.
Michelle Paul's father, Marc Calanog, told the Fort Worth Star-Telegram that he got a text message from Michelle on May 24 saying : "We are both going to doctor now. We have been throwing up for eight hours. David also has diarrhea. My hands are numb."
He said he got a call on May 25 that Michelle was dead, and that David Paul was dead two days later.
David Paul, an Air Force veteran, worked as an engineer at Lockheed Martin in Fort Worth, a company spokesman said. Michelle Paul worked for Marriott International.
Fiji's Ministry of Health and Medical Services said on Wednesday that the investigation is ongoing.
The ministry said staff and health workers who were in contact with the couple are being monitored as a precaution, but that all are currently well.
The ministry said it's also working with local police, the World Health Organisation and the U.S. Centres for Disease Control and Prevention to determine the cause of death.
