The report by Iñigo et al.1 describes two interesting approaches, one epidemiological and the other molecular, to elucidate the proportion of tuberculosis (TB) cases attributable to recent transmission. Considering each approach critically helps us recognize what these two approaches can contribute to our traditional understanding of TB transmission.
Traditional approaches have shown that certain groups are at higher risk for TB (e.g. males, prisoners, the homeless, injecting drug users) and that non-traditional settings in which these groups congregate (e.g. prisons, homeless shelters) are important in facilitating recent TB transmission. However, using traditional approaches, the epidemiological linkages suspected in these non-traditional settings have often been difficult to
