The estimated number of people who are at risk of schistosomiasis who require preventive treatment
Pathak et al. (2016), PeerJ, DOI 10.7717/peerj.1738; 1-14
About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.

Preventing tuberculosis infection from progressing to tuberculosis disease is a crucial component of the goal to eliminate tuberculosis. When deciding on the use of tuberculosis preventive therapy among household contacts, policy makers regularly ask questions, such as whether tuberculosis preventiv...e therapy is effective, safe, and feasible in a programme setting and what it will cost. For contact management and tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis, studies from high-income and low-income countries have shown feasibility, safety, and effectiveness.
However, there is scarce information on the cost of tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis. In The Lancet Global Health, Peter Dodd and colleagues show that household contact management strategies are cost-effective even in low-income and middle-income countries, which has important policy implications for achieving the END TB Strategy goals.

Tuberculosis (TB) prevention is essential for reaching the End TB targets in the South-East Asia Region (SEAR) of World Health Organization (WHO)1. The targets of 80% reduction in TB incidence rate and 90% reduction in TB mortality by 2030 (compared to 2015 levels) can be achieved only with addition...al interventions aimed at preventing TB, according to epidemiological modelling studies commissioned by the WHO South-East Asia Regional Office (WHO SEARO). Optimal implementation of TB preventive treatment (TPT) is a critical intervention to accelerate reduction in TB burden in the SEA Region, which bears nearly 43% of the global TB burden. TPT by itself has the potential to reduce the overall annual TB incidence rates by 8.3% (95% CrI 6.5–10.8) relative to 2015.

The Global Programme on Tuberculosis & Lung Health of the World Health Organization (WHO/GTB) is now combining all current recommendations into one overall set of consolidated guidelines on TB. The guidelines contain recommendations pertaining to all areas related to the programmatic management of T...B (e.g. screening, preventive treatment, diagnostics, patient support, and the treatment of drug-susceptible TB and DR-TB). The consolidated guidelines contain modules specific to each programmatic area.

Human strongyloidiasis is a chronic parasitic disease caused by infection with Strongyloides stercoralis, a soil-transmitted helminth that is estimated to infect 300–600 million people worldwide. This neglected tropical disease (NTD) is endemic globally, predominately in the South-East Asia, Afric...an and Western Pacific regions, and in South and Central America. Strongyloidiasis has a wide range of clinical presentations, including subclinical disease, symptomatic disease (often with diarrhoea, abdominal pain and urticaria) and a rare but deadly complication of hyperinfection with disseminated disease. The feared complication of disseminated strongyloidiasis can occur in the setting of immunocompromising conditions (e.g. human T-cell lymphotropic virus type 1 infection and malignancies) or immunosuppressive medications (e.g. steroids) and has an estimated case-fatality rate exceeding 60%. The standard treatment for chronic S. stercoralis infection is oral medication with ivermectin.

The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.

The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis ...B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.
