Despite notable scientific and medical advances, broader political, socioeconomic and behavioural factors continue to undercut the response to the COVID-19 pandemic1,2. Here we convened, as part of this Delphi study, a diverse, multidisciplinary panel of 386 academic, health, non-governmental organization, government and other experts in COVID-19 response from 112 countries and territories to recommend specific actions to end this persistent global threat to public health. The panel developed a set of 41 consensus statements and 57 recommendations to governments, health systems, industry and other key stakeholders across six domains: communication; health systems; vaccination; prevention; treatment and care; and inequities. In the wake of nearly three years of fragmented global and national responses, it is instructive to note that three of the highest-ranked recommendations call for the adoption of whole-of-society and whole-of-government approaches1, while maintaining proven prevention measures using a vaccines-plus approach2 that employs a range of public health and financial support measures to complement vaccination. Other recommendations with at least 99% combined agreement advise governments and other stakeholders to improve communication, rebuild public trust and engage communities3 in the management of pandemic responses. The findings of the study, which have been further endorsed by 184 organizations globally, include points of unanimous agreement, as well as six recommendations with >5% disagreement, that provide health and social policy actions to address inadequacies in the pandemic response and help to bring this public health threat to an end.

BackgroundTuberculosis in Zambia is a major public health problem, however the country does not have reliable baseline data on the TB prevalence for impact measurement; therefore it was among the priority countries identified by the World Health Organization to conduct a national TB prevalence surveyObjectiveTo estimate the prevalence of tuberculosis among the adult Zambian population aged 15 years and above, in 2013–2014.MethodsA cross-sectional population-based survey was conducted in 66 clusters across all the 10 provinces of Zambia. Eligible participants aged 15 years and above were screened for TB symptoms, had a chest x-ray (CXR) performed and were offered an HIV test. Participants with TB symptoms and/or CXR abnormality underwent an in-depth interview and submitted one spot- and one morning sputum sample for smear microscopy and liquid culture. Digital data collection methods were used throughout the process.ResultsOf the 98,458 individuals who were enumerated, 54,830 (55.7%) were eligible to participate, and 46,099 (84.1%) participated. Of those who participated, 45,633/46,099 (99%) were screened by both symptom assessment and chest x-ray, while 466/46,099 (1.01%) were screened by interview only. 6,708 (14.6%) were eligible to submit sputum and 6,154/6,708 (91.7%) of them submitted at least one specimen for examination. MTB cases identified were 265/6,123 (4.3%). The estimated national adult prevalence of smear, culture and bacteriologically confirmed TB was 319/100,000 (232-406/100,000); 568/100,000 (440-697/100,000); and 638/100,000 (502-774/100,000) population, respectively. The risk of having TB was five times higher in the HIV positive than HIV negative individuals. The TB prevalence for all forms was estimated to be 455 /100,000 population for all age groups.ConclusionThe prevalence of tuberculosis in Zambia was higher than previously estimated. Innovative approaches are required to accelerate the control of TB.

Background Two-thirds of children with tuberculosis have non-severe disease. Method SHINE was an open-label treatment-shortening non-inferiority trial in children with non-severe, symptomatic, presumed drug-susceptible, smear-negative tuberculosis, in Uganda, Zambia, South Africa and India. Children aged <16 years were randomised to 16- versus 24-week standard first-line anti-tuberculosis treatment using WHO-recommended paediatric fixed-dose-combinations and a non-inferiority margin of 6% was used. The primary efficacy outcome was a composite of treatment failure, anti-tuberculosis treatment changes/restarts, on-treatment loss-to-follow-up, TB recurrence or death by 72 weeks, excluding children not reaching 16 weeks follow-up (modified-intent-to-treat). Primary safety outcome was on-treatment grade ≥3 adverse events. Results 1204 children (602 in each group) were enrolled between July 2016 and July 2018; median age 3.5 years (range 2 months-15 years), 52% male, 11% HIV-infected, 14% bacteriologically-confirmed tuberculosis. Retention by 72 weeks and adherence to allocated anti-tuberculosis treatment were 95% and 94%, respectively. Sixteen (3%) versus 18 (3%) children reached the primary efficacy outcome in 16- versus 24-week arms respectively: unadjusted difference -0.4%, 95% CI (-2.2, 1.5). Non-inferiority of 16-weeks was consistent across intention-to-treat, per-protocol and key secondary analyses including when restricting analysis to the 958 (80%) children independently adjudicated to have tuberculosis at baseline. 95 (8%) children experienced grade ≥3 adverse events, including 17 adverse reactions (11 hepatic, all except three occurred within first 8 weeks, when treatment arms were the same). Conclusions 4-months anti-tuberculosis treatment was non-inferior to 6 months for children treated for drug-susceptible non-severe smear-negative tuberculosis.
