A Hidden Summer Hazard: Norovirus Threatens Swimmers


An outbreak of a stomach bug that was tied to swimming in one Oregon lake highlights a perhaps less obvious hazard of summer fun.

Last July, 70 people became ill with norovirus — a very contagious virus that causes vomiting and diarrhea — after visiting a lake near Portland, according to a new report from the Centers for Disease Control and Prevention. More than half of those who got sick were kids ages 4 to 10.

The researchers determined that the lake was likely the source of the infection after they found that people who swam in the lake were about two times more likely to develop vomiting or diarrhea, compared to people who visited the park but didn’t swim, the report said. People typically developed symptoms about a day after they were exposed to the virus.
