Proportion of detection methods responsible for the detection of tuberculosis cases in NSW, 2023

​​Most cases in NSW are tested for TB as they present to a healthcare professional with symptoms of disease ​(70%). Screening for TB (immigration screening, workplace screening​ and other types of screening) leads to the diagnosis of 20% of cases.

Proportion of tuberculosis cases tested for HIV at diagnosis in NSW, 2023

​TB cases are recommended to be screened for HIV, as TB increases the risk of people acquiring HIV infection. Only a small number (1%) of cases are found to have both TB and HIV co-infections.
