North County Times (12.05.12)
The San Diego Health and Human Services Agency reported that a single case of tuberculosis was confirmed at each of two county schools, Vista High School and San Ysidro Middle School. The head of the county’s TB control program, Kathleen Moser, MD, did not believe that the two cases were related, but it was possible for each TB-infected individual to expose others at the two schools.
The period of exposure at Vista High School was August 20 to October 30; 187 students and eight staff members could have come in contact with the infected person. At San Ysidro Middle School, the window of exposure was July 31 to November 28. Ninety-five students and five staff members might have been exposed at San Ysidro Middle School.
Free testing is scheduled at Vista High on December 18 and at San Ysidro Middle School on December 10. Moser recommended that everyone at the two schools participate in the voluntary testing opportunity because TB can remain dormant for years before causing infection. Untreated TB can be fatal.
The county health department reported that 213 cases of TB have been identified in San Diego County so far in 2012. Additional information is available from (619) 692-8632.
