Sorry, wrong Hilton and wrong disease(s).
So, according to the Washington Business Journal:
About 100 guests and 20 workers at a Hilton hotel near Dulles International Airport have been sickened by the highly contagious norovirus, causing the hotel to shut down for several days and put guests in other area hotels. The 449-room Hilton Washington Dulles Airport hotel, at 13869 Park Center Road in Herndon, closed around noon Friday and plans to reopen Tuesday about the same time, says Jim Cree, the hotel’s director of sales and marketing.
The norovirus, a group of related viruses that cause gastrointestinal pains, sickened hotel employees across all departments, he says. The most common symptoms have been stomach pain, diarrhea and vomiting. Hilton is picking up the tab for the guests moved to other hotels.
