An outbreak of viral gastroenteritis continues to affect residents of Cabot House, with about 15 more students admitted to University Health Services (UHS) since Monday morning complaining of nausea, diaharrea and other-flu like symptoms.

An unreported number of other students received intravenous treatment from UHS but were not admitted, according to Cabot House Senior Tutor Robert Neugeboren.

The cases followed an outbreak of illness among Cabot House residents that began Sunday night. Nine of the 15 students admitted to UHS required a police escort to receive treatment.

Ting Wang '02, a Cabot House Undergraduate Council representative, began his own investigation of the outbreak early yesterday morning to find out more about the illness.

In an e-mail sent to all House residents, Wang outlined the reasons for his investigation and asked House members to contribute information regarding time spent in the House, whether students had reported to UHS and whether students had eaten dining hall food.

"As you know, the outbreak of stomach virus epidemic over the weekend afflicted far more than the 15 cases reported by UHS," Wang wrote in the e-mail.

"I believe the investigation by UHS was insufficient," Wang wrote. "It underreported the extent of the epidemic, underestimated the gravity of the situation, and reached a conclusion prematurely."

Last night, Wang said that 86 people--or 22.6 percent of the House--reported that they were got sick between last Saturday and this Wednesday.
