  • Reporting

    Reporting criteria in San Diego County for individuals with latent TB infection: 

    • Child < 2 years old (up to second birthday) with a tuberculin skin test (TST) > 10mm and no BCG vaccination. Please review the child's vaccination history before submitting the report and include it on the CMR.
    • Child < 2 years old (up to second birthday) with a positive interferon gamma release assay (IGRA) test result, (e.g., QuantiFERON or T-Spot), regardless of BCG vaccination status.
    • At least two documented TST or IGRA converters, negative to positive, within two years among children in any one household.
    • Child with a TST > 5mm or a positive IGRA and a symptomatic adult has been identified by the reporter.

     

    Confidential Morbidity Report (CMR) should be filled out and faxed to (858) 514-6532. If chest x-ray results are pending, please wait for results before faxing the CMR. 

    If the child has signs, symptoms, or imaging studies suggesting active TB, please call the TB Reporting Phone # 619-692-8610.

    Active TB Reporting & Guidelines

    Confidential Morbidity Report (CMR)

    Reports of young children with LTBI are used to identify the individual who infected the child. This is because LTBI in a child indicates recent transmission. Treatment of the child remains the responsibility of the provider. Any information regarding someone with signs or symptoms consistent with TB in the child's environment should be included on the CMR.

    Civil surgeons conducting status adjustment medical exams have a federal requirement to report LTBI to the local health department.

    • Civil surgeons should follow the same instructions above for submitting a CMR to report LTBI identified on status adjustment medical exams. 
    • The TB program will send each patient a letter following receipt of the report, emphasizing the importance of LTBI treatment and providing guidance on how to obtain LTBI treatment, if not initiated by the civil surgeon.
