The senior Saudi prince who is governor of Riyadh is in intensive care with the coronavirus. Several dozen other members of the royal family have been sickened as well. And doctors at the elite hospital that treats Al-Saud clan members are preparing as many as 500 beds for an expected influx of other royals and those closest to them, according to an internal “high alert” sent out by hospital officials.“Directives are to be ready for V.I.P.s from around the country,” the operators of the elite facility, the King Faisal Specialist Hospital, wrote in the alert, sent electronically Tuesday night to senior doctors. A copy was obtained by The New York Times.“We don’t know how many cases we will get but high alert,” the message stated, instructing that “all chronic patients to be moved out ASAP,” and that only “top urgent cases” will be accepted. It said any sick staff members would now be treated at a less elite hospital to make room for the royals.More than six weeks after Saudi Arabia reported its first case, the coronavirus is striking terror into the heart of the kingdom’s royal family.
