Mathis Blondeau, a 23-year-old French business student and rugby player from Quimper, died on October 27, 2026, after contracting severe dengue fever while traveling in Vietnam.

His sudden passing has deeply affected his family, classmates, and rugby teammates, who are preparing a tribute in Quimper on November 8.
What Happened to Mathis Blondeau?
Mathis Blondeau died on Tuesday, October 27, 2026, following complications from dengue fever in Vietnam.
The young Frenchman had been traveling through Southeast Asia during a break from his business studies.
He had previously visited Bali, Indonesia, before continuing his journey to Vietnam.
During his stay, Mathis became seriously ill after contracting dengue, a viral infection transmitted by infected mosquitoes.
His condition deteriorated, and he died at just 23 years old.
The news shocked those who knew him in France, particularly members of the rugby community in Brittany and the Lyon metropolitan area.
Was Mathis Blondeau in an Accident?

There is no confirmed evidence supporting claims that he was involved in a fatal road accident in Vietnam.
His death highlights the potentially serious consequences of dengue infection, even among young and physically active adults.

The infection occurs in many tropical and subtropical regions, including parts of Southeast Asia.
Common symptoms include high fever, severe headache, muscle and joint pain, nausea, and skin rash.
Most infected people recover, but some develop severe dengue.
