The Hilton hotel near Dulles International Airport has been closed for a top-to-bottom scrubbing after more than 100 guests were sickened by the highly contagious norovirus, a hotel spokesman said Friday.

A total of 120 people, including 105 guests and 15 employees, have fallen ill, said Jim Cree, the hotel's director of sales and marketing. Outbreaks of norovirus, which causes vomiting and diarrhea, are common on cruise ships and in places like hotels, prisons and nursing homes.

Cree said hotel officials first heard reports of sick guests Wednesday morning and contacted Fairfax County health authorities. He said officials confirmed it was norovirus Thursday evening.

"Yesterday we stopped taking reservations," Cree said. "Today we're actually relocating guests, and we've relocated all of our events to other hotels."

Cree said the hotel would reopen Tuesday at noon.
