CDC confirms new strain of norovirus
The U.S. Centers for Disease Control and Prevention has found that recently tested samples submitted by
state health officials contain a new strain of norovirus.
The CDC reports the new strain, like other norovirus strains, is transmitted person to person, and has been confirmed nationwide for about 50 percent of recent outbreaks.
In Louisiana, officials said Thursday that the strain has sickened dozens and forced the recent closure of some oyster harvest areas. The new strain, GII.4 New Orleans, includes the city's name because the first confirmed samples came from there.
