[3] [4] [5] Those at high risk include household, workplace, and social contacts of people with active TB. [4] Treatment requires the use of multiple antibiotics over a long period of ...
He is widely published in tuberculosis epidemiology, diagnosis and control with media coverage including research on tuberculosis screening, [35] work showing high risk of TB in pregnancy and the postpartum period, tuberculosis and air travel, [36] and on the effects of BCG in TB prevention. [37]
This test is the first choice of diagnostic test for high risk population, children, contacts of drug resistant cases and PLHA(Patient Living With HIV AIDS) .
