I had a friend - worked as a nurse at the Royal Darwin Hospital - who came up heavily positive for TB...she took several months worth of antibiotics etc and hasn't had any problems since.
Yes TB is still in circulation in the population - especially out in some of the aboriginal communities where the general standard of health/access to health care is appallingly low. PPl who have travelled in Asia or who spend a lot of time with ppl who have travelled in Asia can also be susceptible as there are higher levels of TB prevalence there too. Hence a higher TB rate in the NT too.
