ATLANTA - Health officials say poor hygiene may have been responsible for an outbreak of the Norwalk virus that sickened at least 19 college students last month. <br>
<br>
The students were attending a convention of the Pi Sigma Epsilon marketing and sales profession fraternity at the Omni Hotel in downtown Atlanta. Those who became sick reported nausea, vomiting and diarrhea. <br>
<br>
Doctor Adewale Troutman - director of the Fulton County Department of Health and Wellness - said investigators questioned several of the stricken students after they went home. He said many said they were sick before they came to the convention. <br>
<br>
Investigators believe those students spread the virus by not washing their hands properly and then shaking hands with other students. <br>
<br>
At first, officials suspected food poisoning but inspectors found no health violations in the hotel's kitchen or with food and staff, health officials say.
