Ask a Virologist: Found Water on the Trail, Is it Safe?

As summer progresses and we make our way higher and higher into the alpine to explore trails and escape the valley heat, there comes the urge to splash some creek water on one's face or perhaps to fill a water bottle from same. Inevitably we wonder, "is this stream's water safe for consumption?"

For an answer, we ask a virologist: Found Water on the Trail, Is it Safe?
