CrAssphage as a Novel Tool to Detect Human Fecal Contamination on Environmental Surfaces and Hands

Jul 21, 2020

CrAssphage is a recently discovered human gut–associated bacteriophage. The presence of crAssphage does not correlate with norovirus contamination but rather with human fecal contamination. Detection of crAssphage on environmental surfaces might help to better assess exposure risk for human norovirus in public areas (e.g., on cruise ships) as well as help to identify frequently touched surfaces that are often fecally contaminated as key sites for enhanced cleaning practices.
