The restaurant remains closed, and Santa Clara health officials say 11 of the Shigella victims have been treated in intensive care units at area hospitals.
All of those stricken with the intestinal infection that causes fever, abdominal pain and diarrhea report dining at the San Jose restaurant on either the previous Friday or Saturday.
Shigella is a pathogen that usually can be treated successfully with antibiotics. Local health officials said Monday that they expect the number of those sickened will grow, and they issued a request for action by all clinicians in the area.
