Health District Seeks Information on Norovirus-like Illnesses

After voluntary closure, Altitude Trampoline Park reopens Wednesday

SNOHOMISH COUNTY, Wash. – Following reports of individuals being sickened with Norovirus-like symptoms over the weekend, the Snohomish Health District is activating a temporary call center. Anyone who visited the Altitude Trampoline Park located at 6610 64th Street Northeast in Marysville on or after March 10, and has exhibited symptoms consistent with norovirus, is encouraged to call 425-388-5088. The call center will be staffed from 8 a.m. to 5 p.m. through Friday, or unless an outbreak increases.

Norovirus is a disease that spreads quickly, oftentimes mistakenly called the stomach flu. You can get norovirus from an infected person, contaminated food or water, or by touching contaminated surfaces. The virus causes stomach pain, nausea, diarrhea and vomiting because your stomach, intestines or both get inflamed (acute gastroenteritis). Symptoms include:

  • A sudden onset of illness, usually 24-48 hours after exposure
  • Vomiting and nausea
  • Diarrhea and stomach cramps
  • Headaches, chills, a low-grade fever, muscle aches and tiredness
  • Symptoms lasting for 1-2 days

“While it’s not considered a reportable condition, we do follow up on cases of gastrointestinal illnesses like norovirus when they might be part of a larger outbreak,” said Nancy Furness, director of the Snohomish Health District’s communicable disease division. “Schools, daycares and other places where large numbers of children play—like trampoline parks—can be prime spots for the germs spread quickly.”

Health District staff have reached out to Altitude Trampoline Park as a resource and to offer assistance as needed. David Jones were notified that the business voluntarily closed for thorough cleaning on Tuesday, March 14.

David Jones at Altitude Trampoline stated that “our customers are our highest priority and we voluntarily closed to ensure the facility received an extra cleaning. The facility is cleaned on a daily basis but yesterday’s cleaning was an extra measure of that. Our staff have also been provided additional training on proper protocols for cleaning.”

The Communicable Disease division will be monitoring reports made to the Health District to see whether these cases may be part of a larger outbreak. Parents or ill individuals are encouraged to contact their health care providers for persistent symptoms or questions. 

There are no specific drugs or vaccines to treat or prevent norovirus. However, taking the following precautions will help prevent the spread of the virus:

  • Wash hands after using the bathroom
  • Wash fruits and vegetables thoroughly
  • Do not prepare food for others while sick
  • Keep children with symptoms home from school or child care, and notify them of the illness
  • Clean and disinfect contaminated surfaces with a solution of bleach and water
  • Wash all clothes and linens soiled by vomit or fecal matter immediately
