The state Department of Health is investigating a fifth possible case of dengue fever in Hawaii reported by Kaiser Permanente Medical Center.

Being tested is a blood sample from Mimi Allgire, 51, of Makiki, who came down with a fever of 102.5 degrees and severe leg pain.

The Health Department announced Thursday two confirmed and two suspected cases of dengue fever in a Pearl City family and a neighbor last month, the first locally contracted cases in 10 years. All have recovered. Results of the two suspected cases are expected in a week.

On March 21 Allgire saw a doctor, who treated her for the flu and sent her home with Vicodin for her pain, said her husband, KITV news reporter Dick Allgire. Her condition did not improve, so she returned last Tuesday to the emergency room.

She also had rash on her legs and stomach.

Mimi Allgire returned again on Saturday and was given morphine for her pain, Dick Allgire said.

It was then "the doctor said, ‘This is dengue fever,’" Dick Allgire said.

It’s not 100 percent certain, he said, but the doctor consulted with an infectious disease specialist who confirmed the symptoms appeared to be in line with dengue.

Mimi Allgire’s blood sample was sent to the Centers for Disease Control for testing, he said.

She has not traveled outside the state, Dick Allgire said, and has not gone outside the Makiki-Kapiolani-Kaimuki area and does not recall being bitten by mosquitoes.
