Las Vegas school district opens tuberculosis investigation after infected person visits dozens of schools

Officials have opened a tuberculosis investigation after a person with an active infection was reported to have been on dozens of elementary and high school campuses in Nevada’s most populous county, according to the Associated Press. 

The person in question, who has not been publicly identified, was believed to have been on 26 Clark County School District campuses and a training site before discovering the TB diagnosis, AP reported. 

The Southern Nevada Health District also released a list of affected schools on Friday and notified people who were believed to be in close contact with the person. 

The district said individual notifications were happening at 17 campuses for possible exposures, but no exposures had been identified at eight campuses so far, according to the AP.
