Norwalk shedding for weeks

By  |  November 30, 2008 | 

Norwalk virus is the most frequent cause of epidemic non-bacterial gastroenteritis worldwide (CDC link). It is highly pathogenic and extremely contagious, but symptoms usually only last for about a day. However, in this study, researchers found the fecal shedding of norwalk (in experimentally infected healthy adults) lasted for a median of 1 month, and as long as 2 months in some (abstract). It is important for us to realize the potential prolonged infectivity (even after resolution of diarrhea) of patients with recent Norwalk gastroenteritis.
