Two separate tuberculosis (TB) cases have prompted health investigations at high schools in Michigan and California, according to recent health department announcements.
In Kalamazoo County, Michigan, officials are investigating an active TB case in a high school student. The student is currently isolated and receiving treatment. The Kalamazoo County Health & Community Services Department is working with local school authorities to test individuals who may have been in contact with the infected student.
Meanwhile in San Diego, health officials have issued a warning about potential TB exposure at Palomar High School between February 24 and June 5, 2024. Students, staff, and contractors who may have been exposed are being notified.
The San Diego situation comes amid rising TB numbers in the county, which reported 243 active cases in 2023 - the highest level in 5 years. Health officials note that TB cases had been declining since 2000 but began increasing in 2020. An estimated 175,000 San Diego County residents have latent TB infections, with 5-10% at risk of developing active TB during their lifetime.
Dr. William Nettleton, medical director of Kalamazoo County HCS, emphasized that while TB is serious, it remains treatable with proper medical care. Both health departments are closely monitoring the situations and implementing necessary precautions to protect student and staff health.
Local health authorities in both regions continue working with school administrators to identify and test individuals who may have been exposed, while providing guidance on prevention measures.
