  • Potential impact, costs, and benefits of population-wide screening interventions for tuberculosis in Viet Nam

    Open AccessAlvaro Schwalb, Katherine C Horton et al.ARTICLEPLOS Global Public Health2025

    Population-wide screening may accelerate the decline of tuberculosis (TB) incidence, but the optimal screening algorithm and duration must weigh resource considerations. We calibrated a deterministic transmission model to TB epidemiology in Viet Nam. We simulated three population-wide screening algorithms from 2025: sputum nucleic acid amplification tests (NAAT, Xpert MTB/RIF Ultra) only; chest radiography (CXR) followed by NAAT; and CXR-only wit…

  • Subnational tuberculosis burden estimation for Pakistan

    Open AccessAlvaro Schwalb, Zia Samad et al.ARTICLEPLOS Global Public Health2024

    Global tuberculosis (TB) burden estimates are aggregated at the national level, despite the likelihood of uneven distribution across and within regions in the same country. Subnational estimates are crucial to producing informed policies and informing budget allocation at more granular levels. In collaboration with the National TB Programme (NTP), we applied a simple and transparent tool to estimate the subnational TB burden in Pakistan. We tailo…

  • Association between HTLV-1/2 infection and Covid-19 severity in a migrant Shipibo-Konibo population in Lima, Peru

    Open AccessFátima Avila Dextre, Bryan Morales Álvarez et al.ARTICLEPLOS Global Public Health2024

    Objectives The migrant community of the Shipibo-Konibo indigenous people in Lima, Peru were extremely vulnerable during the COVID-19 pandemic. Additionally, infection with human T-cell lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in this population causing immunosuppression. The aim of the study was to describe the association between HTLV-1/2 infection and the clinical severity of COVID-19. Methods This was a cross-sectional descriptive…

  • Impact of micro- and macronutrient status on the incidence of tuberculosis

    Open AccessAlvaro Schwalb, Malin Bergström et al.ARTICLEPLOS Global Public Health2023

    Macronutrient and micronutrient deficiencies are associated with tuberculosis (TB) incidence. However, evidence is limited on the impact of micronutrient (vitamins and minerals) supplementation among underweight individuals. We conducted a secondary data analysis of a randomised controlled trial of lipid nutritional supplements with and without high-dose vitamin and mineral supplementation (LNS-VM vs LNS) for underweight (Body Mass Index [BMI] 2 …

  • Know your tuberculosis epidemic–Is it time to add Mycobacterium tuberculosis immunoreactivity back into global surveillance

    Open AccessHannah M Rickman, Wala Kamchedzera et al.ARTICLEPLOS Global Public Health2022

    Tuberculosis (TB) still causes 1.5 million deaths globally each year. Over recent decades, slow and uneven declines in TB incidence have resulted in a falling prevalence of TB disease, which increasingly concentrates in vulnerable populations. Falling prevalence, while welcome, poses new challenges for TB surveillance. Cross-sectional disease surveys require very large sample sizes to accurately estimate disease burden, and even more participants…

  • Prevalence of positive TST among healthcare workers in high-burden TB setting in Peru

    Open AccessJuana Sedamano, Alvaro Schwalb et al.ARTICLEBMC Public Health2020

    This study supports previous reports that TB infection is an occupational hazard for HCWs. Prevention of TB transmission through control measures, as well as timely diagnosis of LTBI in this particular high-risk group, is critical for individual and public health
