Chanchai Phanthongwiryakun, Director of the Srinakarin Hospital, said she was moved to the ICU on July 11 due to severe loss of blood, which led to failures of internal organs like kidney, liver and heart.
"It's the severe and rare type of dengue fever," Charnchai said. "It's under investigation where and how she was infected," he said.
The student was the first patient who died of dengue fever in Khon Kaen this year.
A provincial public health officer said that dengue fever infection rate in Khon Kaen has tripled from last year. Since January, 1,061 patients have been diagnosed with the fever. A war room has been set up, to monitor the spread on a weekly basis.
