1 Includes the number of risk factors reported (which may be more than one per case) and the number of cases with no information on additional risk factors.  The sum of risk factors is greater than the total number of cases because more than one risk factor may be selected per case.
2 Excludes TB risk factor information for 16 cases with unknown origin.
3 Includes risk factor responses of MDR patient contact, missed contact, and infectious TB patient contact.
4 Includes risk factor responses of end-stage renal disease and non-HIV immunosuppression.
5 Includes risk factor responses of incomplete LTBI therapy and Other.
6 Persons of Hispanic/Latino origin may be of any or multiple race.
7 Indicated two or more races reported for a person, and does not include persons of Hispanic/Latino origin.
