EL MONTE (CBSLA.com) — As many as 1,000 students who attended summer school at Arroyo High School last year may have been exposed to tuberculosis, according to the Associated Press.
Los Angeles County health officials notified the El Monte Union High School District this week after learning a student who attended classes at the school tested positive for the disease, the San Gabriel Valley Tribune reported.
Anyone who took classes at the school in summer of 2012 is being urged to be tested for the disease.
Earlier this month, health officials notified school officials at Cal Poly Pomona that as many as 375 students and 20 faculty may have been exposed to the bacterial infection.
An unidentified person at Whittier High School tested positive for the disease in February.
Federal health officials were also called in earlier last month to stop a reported outbreak of a drug-resistant strain of tuberculosis in the Skid Row section of downtown Los Angeles.
