In this low-incidence, high-resource setting, patient delays contribute most to total delay in PTB diagnosis. Strategies addressing this aspect of the TB diagnosis pathway, such as health literacy and promotion programmes for new migrants and raised primary healthcare awareness, could have the largest impact on reducing total PTB diagnosis delays.

Pneumonia severity scoring systems have been developed to identify patients at highest mortality risk, and are used in guidelines to limit use of broad-spectrum antibiotics to patients with severe community-acquired pneumonia. A retrospective audit of hospitalised general internal medicine patients with pneumonia was performed to assess the diagnostic performance of various pneumonia severity scores in an elderly general internal medicine population.

There has been increased interest in using metagenomic next-generation sequencing as an unbiased approach for diagnosing infectious diseases. We describe a 61-year-old man on fingolimod therapy for multiple sclerosis with an extensive travel history who presented with 7 months of fevers, night sweats, and weight loss. Peripheral blood tests showed pancytopenia and abnormal acute phase reactants. A bone marrow aspirate showed the presence of numerous intracellular and extracellular amastigotes consistent with visceral leishmaniasis (VL). Metagenomic sequencing of the bone marrow aspirate confirmed Leishmania infantum, a species widely reported in the Mediterranean region. This correlated with acquisition of VL infection during the patient's most recent epidemiological exposure in southern Italy 12 months prior. This case demonstrates the potential application of metagenomic sequencing for identification and speciation of Leishmania in cases of VL; however, further assessment is required using other more readily obtained clinical samples such as blood.
