FYI: The incidence of TB was estimated at 432 per 100 000 (range 352–521) with an estimated mortality rate of 40 per 100 000 (excluding HIV). Papua New Guinea currently has the second highest TB incidence in the WHO Western Pacific Region and tenth highest globally (World Health Organization, 2016a). Multidrug-resistant TB (MDR-TB) was estimated to be present in 3.4% (1.7–5%) of new cases and 26% (15–36%) of previously treated cases in 2015 (World Health Organization, 2016a). There have been 254 laboratory-confirmed MDR-TB (rifampicin-resistant) cases, and 11 confirmed cases of extensively drug-resistant TB (XDR-TB) (World Health Organization, 2016a). For MDR-TB, the majority of the cases diagnosed are in the hotspot areas of Daru Islands, Western Province and the National Capital District, which has a high TB notification rate (four times more than the national average) and contributes to 25% of the country’s TB burden despite hosting only 5% of the country’s population. A prospective study in Kikori District in Gulf Province reported a prevalence of 1290 per 100 000 people (95% CI: 1140–1460) in 2012 (Cross et al., 2014). Three of the 32 TB only cases tested were rifampicin resistant. In conclusion the study stated that TB was found to not be driven by HIV coinfection, as the proportion of TB/HIV co-infected cases was only 1.9%.
