  • Roughly 24 hikers reported norovirus symptoms along the Pacific Crest Trail near Wrightwood after illnesses began surfacing around May 8, and at least seven cases were medically confirmed.
  • A shared water cache in Swarthout Valley between Cajon Pass and Mount Baden-Powell is an early suspected source, though officials have not confirmed the contamination point.
  • One hiker was airlifted after becoming too ill to continue, underscoring how vomiting, diarrhea and dehydration can turn dangerous quickly in remote backcountry settings.
  • The 2,650-mile trail’s limited sanitation and shared campsites, food and water make outbreaks hard to contain, especially because hand sanitizer does not reliably kill norovirus.
  • CDC data show norovirus causes 19 million to 21 million U.S. illnesses a year, making the PCT outbreak a reminder that common stomach viruses can spread fast even outdoors.
Beyond the PCT, could this outbreak signal a growing public health risk on America's most popular trails?
Are popular backpacking water filters giving hikers a false sense of security against the spreading norovirus?
