Each year in March, the number of TB cases diagnosed the year before are reported to the public. Tracking TB diagnoses and subpopulations affected disproportionately directs public health department efforts statewide to allocate resources and strategies to prevent and control TB.
Below is a summary of TB by the numbers in California 2020:
There are more than 2 million Californians living with latent TB infection (LTBI). LTBI is when the TB bacteria are found in the body but not causing symptoms, illness and cannot be spread to others.
85% of those diagnosed with TB disease in California in 2020 developed TB from LTBI.
84% of those diagnosed with TB disease in California in 2020 were born outside of the U.S.
52% of those diagnosed with TB disease in California in 2020 were born in Asia.
40% of adult TB cases had diabetes, end stage renal disease, HIV infection, or another health condition that increases the likelihood that LTBI will progress to TB disease.
Only 20% of those with LTBI are aware that they are living with LTBI.
11 (1.0%) of those diagnosed with TB in California in 2020 had multidrug resistant (MDR) TB.
California has not seen an increase in MDR TB diagnoses since routine testing for TB drug sensitivity began in 1993.
