Outbreak of Gastrointestinal Illness Among Biking Across Kansas
ParticipantsIdentified as Norovirus

The Kansas Department of Health and Environment (KDHE) has identified norovirus as a cause for at least some of the cases of gastrointestinal illness among several participants of the Biking Across Kansas (BAK) tour.

About 850 people from 33 states, including Kansas, participated in the tour. In addition to Kansas, KDHE epidemiologists have identified ill persons from ten states.

Twelve BAK participants have tested positive for norovirus through the KDHE Division of Health and Environmental Laboratories; one of these persons has also tested positive for rotavirus through a private laboratory. Some samples are being sent to the state public health laboratory in Minnesota for further testing.

"We're continuing our investigation to determine the scope of these illnesses and what factors may have contributed to the outbreak," said Dr. Howard Rodenberg, Director of the KDHE Division of Health and State Health Officer. "We appreciate everyone's cooperation and continued patience as this process unfolds."

Both norovirus and rotovirus illnesses cause nausea, vomiting, diarrhea, and some stomach cramping. Some also experience a low-grade fever, chills, headache, muscle aches and fatigue. Symptoms usually last about one or two days.

These viruses are easily spread. Food handlers should not prepare food for three days after recovery from any diarrheal disease. Symptomatic persons should also refrain from working with the young and the elderly and should not be involved in patient care. Children who are sick must not attend school or day care.

To prevent the spread of these illnesses:

• Wash hands frequently, especially after using the bathroom, changing diapers, and before preparing food and eating
• Carefully wash fruits and vegetables
• Thoroughly clean and disinfect contaminated surfaces, such as bathroom fixtures and toys, with a bleach-based cleaner or other disinfectant
• Immediately remove and wash clothing and linens with soap and hot water after being soiled
• Refrain from preparing food or caring for others if you have diarrhea
