First reports of Arafat's treatment by his doctors for what his spokesman said was the "
flu" came on
October 25, 2004, after he vomited during a meeting. His condition deteriorated in the following days. Following visits by other doctors, including teams from Tunisia, Jordan, and Egypt – and agreement by Israel not to block his return – Arafat was taken on aboard a French government jet to the
Percy military hospital in
Clamart, near Paris. According to one of his doctors, Arafat was suffering from
Idiopathic thrombocytopenic purpura (ITP), an immunologically-mediated decrease in the number of circulating platelets to abnormally low levels. On
November 3, he lapsed into a gradually deepening coma. In the ensuing days, Arafat's health was the subject of some speculation, with suspicion that he was suffering from
poisoning or
AIDS. Various sources speculated that Arafat was
comatose, in a "vegetative state" or dead, however, Palestinian authorities and Arafat's Jordanian doctor denied reports that Arafat was brain dead and had been kept on life support.
A controversy erupted between officials of the PA and Suha Arafat when officials from the PA traveled to France to see Yasser Arafat. Suha stated "They are trying to bury Abu Ammar [Arafat] alive". French law forbids physicians from discussing the condition of their patients with anybody with the exception, in case of grave prognosis, of close relatives. Accordingly, all communications concerning Yasser Arafat's health had to be authorized by Arafat's wife. Palestinian officials expressed regret that the news about Yasser Arafat was "filtered" by her.
The next day, chief surgeon Christian Estripeau of Percy reported that Arafat's condition had worsened, and that he had fallen into a deeper coma.
Sheikh Taissir Tamimi, the head of the
Islamic court of the Palestinian territories – who held a vigil at Arafat's bedside – visited Arafat and declared that it was out of the question to disconnect Arafat from life support machines since, according to him, such an action would be prohibited by Islam.
Arafat was pronounced dead at 3:30 am
UTC on
November 11 at the age of 75. The exact cause of his illness is unknown. Tamimi described it as "a very painful scene." When Arafat's death was announced, the Palestinian people went into a state of mourning, with
Qur'anic mourning prayers emitted from mosque loudspeakers and tires burning in the street as a sign of remorse. The PA declared an official mourning that lasted for forty days. One obituary at
Socialist World said: "Many Palestinians will view the death of Yasser Arafat with a mixture of sadness and a wish that the Palestinian Authority he led, had done much more to end the poverty and oppression that blights their lives".
The
Canard Enchaîné newspaper reported alleged leaks of information by unnamed medical sources at Percy hospital who had access to Arafat and his medical file. According to the newspaper, the doctors at Percy hospital suspected, from Arafat's arrival, grave lesions of the liver responsible for an alteration of the composition of the blood; Arafat was therefore placed in a
hematology service.
Leukemia was soundly ruled out. According to the same source, the reason why this diagnosis of
cirrhosis could not be made available was that, in the mind of the general public, cirrhosis is generally associated with the consequences of alcohol abuse. Even though the diagnosis was not of an alcoholic cirrhosis and Arafat was not known for consuming any alcohol, there was a likelihood of rumors. The source explained that Arafat's conditions of life during the last three years did not improve the situation: Arafat did not get health care appropriate to his state. Thus, according to the source, the probable causes of the disease were multiple; Arafat's coma was a consequence of the worsened cirrhosis. The French newspaper
Le Monde quoted doctors as saying that he suffered from "an unusual blood disease and a liver problem".
After Arafat's death, the
French Ministry of Defense said that Arafat's medical file would only be transmitted to his
next of kin. It was determined that Arafat's nephew and PA envoy to the UN, Nasser al-Qudwa, was a close enough relative, thus working around Suha Arafat's mutism on her husband's illness. Nasser al-Qudwa was given a copy of Arafat's 558-page medical file by the French Ministry of Defense.
