In September 2005, an Israeli-declared AIDS expert claimed that Arafat bore all the symptoms of AIDS based on obtained medical records. But others, including Patrice Mangin of the University of Lausanne and "The New York Times", disagreed with this claim, insisting that Arafat's record indicated that it was highly unlikely that the cause of his death was AIDS. Arafat's personal doctor Ashraf al-Kurdi and aide Bassam Abu Sharif maintained that Arafat was poisoned, possibly by thallium. A senior Israeli physician concluded that Arafat died from food poisoning. Both Israeli and Palestinian officials have denied claims that Arafat was poisoned. Palestinian foreign minister Nabil Shaath ruled out poisoning after talks with Arafat's French doctors.
