Norovirus only large outbreak among Katrina evacuees

The Centers for Disease Control and Prevention said Tuesday that there was only one outbreak of disease among evacuees or rescue workers that required unusual mobilization of public health resources during the first three weeks after Hurricane Katrina.
That disease was norovirus, a highly contagious but usually self-limiting outbreak of nausea, vomiting and diarrhea common among cruise ship passengers that was reported among evacuees in Texas, the CDC said in a summary of post-Katrina illness. Symptoms can also include low-grade fever, chills, headache, muscle aches and a general sense of tiredness.
