The majority of TB cases in NSW are new cases (95%) in people who have not previously been diagnosed with TB. Two cases were confirmed relapses with the same TB strain on whole genome sequencing.
The majority of TB cases have pulmonary disease, either as a single disease site (60% of cases) or pulmonary disease with another site (9% of cases).
Most cases in NSW are tested for TB as they present to a healthcare professional with symptoms of disease (66%). Screening for TB (immigration screening, workplace screening, contact screening and other types of screening) leads to the diagnosis of 23% of cases.
TB cases are recommended to be screened for HIV, as HIV significantly increases the risk of TB mortality. Only a small number (1%) of cases are found to have both TB and HIV co-infections.
