Hotel Shut Down After Guest Become ill (6/7/03 - Herndon) The Hyatt Hotel in Herndon has been shut down for the weekend after 60 guests became ill. Officials with the state Health Department believe it's the Norovirus, similar to the one that sickened passengers on several cruise ships earlier this year. The virus causes nausea, vomiting, abdominal cramps and diarrhea and usually lasts 12 to 60 hours. Most people become sick within 24 to 48 hours after being exposed. The Health Department and the hotel are working together to thoroughly disinfect the building and officials at the Hyatt hope to reopen on Monday. Guests at the hotel who aren't ill have been asked to go home or have been transferred to another Hyatt Hotel in Reston. From www.fox5dc.com Live spot on tv said it was blamed on a person with "poor personal hygiene". Let's wash those hands people!
