Yes, influenza followed by hemorrhagic cerebrovascular accident.
Yasser Arafat
The first reports of Arafat's failing health by his doctors for what his spokesman said was influenza came on 25 October 2004, after he vomited during a staff meeting. His condition deteriorated in the following days. Following visits by other doctors, including teams from Tunisia, Jordan, and Egypt—and agreement by Israel to allow him to travel—Arafat was flown from Ramallah to Jordan by a Jordanian military helicopter and from there to France on a French military plane. He was admitted to the Percy military hospital in Clamart, a suburb of Paris. On 3 November, he had lapsed into a gradually deepening coma.

Arafat was pronounced dead at 03:30 UTC on 11 November 2004 at the age of 75 of what French doctors called a massive hemorrhagic cerebrovascular accident (hemorrhagic stroke).
