Infectious diseases are always a risk, especially when they are undiagnosed and can get even more people infected. San Diego is currently on alert due to an active tuberculosis (TB) case due to a passenger who used the trolley and the bus routes all the way from San Ysidro.

San Diego County Health and Human Services Agency (HHSA) shared the alert to users who used Metropolitan Transit System (MTS) services between February 16, 2022 and August 16, 2022.

HHSA shared a list of possible routes that the infected rider could have taken:

  • Trolley Blue Line from San Ysidro to 12th and Imperial station Monday through Friday from 6 a.m. to 6:30 a.m.
  • Trolley Orange Line from 12th and Imperial to Lemon Grove Monday through Friday from 6:30 to 7 a.m.
  • Trolley Orange Line from Lemon Grove to 12th and Imperial Monday through Friday roughly between 4:45 p.m. and 5:15 p.m.
  • Trolley Blue Line from 12th and Imperial to San Ysidro Monday through Friday roughly between 5:15 p.m. and 5:45 p.m.

It should be noted that an alert had previously been issued about this same disease. However, different bus and trolley lines were identified, which are also a part of this list, and the usage is still being limited from February 16, 2022 to August 16, 2022. The routes were the following:

  • Bus route 950 from Otay Mesa Transit Center toward Iris Avenue Transit Center Monday through Friday between 4:30 a.m. to 6 a.m.
  • Bus route 950 from Iris Avenue Transit Center to Otay Mesa Transit Center from 3p.m. to 5 p.m.
  • Blue Line Trolley from Iris Avenue to H Street from 5 a.m. to 6:30 a.m.
  • Blue Line Trolley from H Street to Iris Avenue from 2:30 p.m. to 5 p.m.

Wilma Wooten, M.D., M.P.H., County Public Health Officer stated:

Symptoms of active TB include persistent cough, fever, night sweats and unexplained weight loss. Most people who are exposed do not develop the disease and TB can be treated and cured with medication.

Passengers that could be potentially infected must go to the doctor or contact the County TB Control Program at (619) 692-8621 to schedule a test. So far, in 2022, 97 cases of tuberculosis have been detected in the county. MTS employees will be tested by a workplace health program.
