City officials declared a public health emergency Thursday after a tuberculosis outbreak left one person dead and nine others hospitalized.

Health officials said the outbreak stemmed from a group of people who stayed together at a Long Beach hotel room.

As of April 29, 14 cases of tuberculosis (TB) are associated with this outbreak — nine of them required hospitalization and one case was fatal.

Investigators said around 170 people have likely been exposed to the illness. Health officials are in contact with any guests or individuals who were at the hotel during the time the infected people were present.
