"Although they were provided medical treatment as standard of care, their illnesses progressively worsened and despite best efforts, they died within a few days of each other", the statement said.
While the cause of death remains under investigation, the family says that early indications point to some type of virus that was strong enough to debilitate two healthy, young people.
"The Embassy has facilitated contact between the U.S. Centers for Disease Control and Fiji's Ministry of Health to ascertain the causes of death and to assist in any related measures".
A young Texas couple died suddenly while on vacation in Fiji after coming down with a mystery illness, their family said. 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.
In an attempt to find Zooey, Calanog said she called numerous local dog kennels and posted about her on social media until she was successful in reuniting with the pup.More news: Four dead in northern Australia shooting

David Paul worked for Lockheed Martin as a sustainment group engineer, according to company spokesman Kenneth Ross. Their beloved pet dog Zooey had been left at a boarding kennel, but relatives did not know which one. "I've never seen a community like Fort Worth come together for complete strangers to help find a family member".
The US Embassy in Fiji, who were contacted for comment by KVUE, didn't comment specifically on the couple's death, but said there has been warnings of a unsafe flu affecting the island nation.
A U.S. Department of State official has expressed its condolences to the surviving family members and are waiting for an outcome to the investigation into the couple's deaths.
While their families have been told that they died, they remain in the dark about what caused their sudden deterioration of health.
Calanog said the cause of death must be determined before the bodies are returned to the United States, and if an infectious illness is found to be the cause, their bodies will have to be cremated. "We know Michelle and David are with us in Zooey".
