- The result depends on the size of the raised, hard area or swelling.

What is the WHO recommended rapid diagnostic test for TB?
Molecular WHO-recommended rapid diagnostic tests for TB(mWRDs; eg Xpert MTB/RIF) were reviewed for use as TB screening tools among different populations at high risk of TB. Evidence shows improved accuracy and effectiveness in people living with HIV and in other high-risk populations. The evidence is strongest for hospitalized patients with HIV in settings with a high burden of TB, given the limited value of symptom screening and the grave consequences of missing the opportunity to initiate TB treatment promptly in this patient group. Based on these updates, a set of 17 new and revised recommendations for screening for TB disease have been developed (Table 1). The main changes from the previous WHO guidance are summarized in Box 1. The new guidelines replace all previous WHO guidance on TB screening. The recommendations are accompanied by updated operational guidance, the WHO operational handbook on tuberculosis. Module 2: screening – systematic screening for tuberculosis disease, that includes further details on target populations and tools to use for systematic screening, including revised algorithms and modelled estimates of their performance.

How many people die from TB in 2016?
Tuberculosis (TB) is a major public health problem throughout the world by infecting an estimated one-third of the world’s population and putting them at risk of developing active disease during their lifetime. Tuberculosis is the leading cause of deaths every year among the infectious disease worldwide alongside HIV. It kills more than five thousand children, women and men each day. According to the Global TB Report 2017, 10.6 million people are estimated to have fallen ill with TB in 2016 while an estimated 1.3 million people died of TB. In addition, an estimated 4.1% of these new TB cases and 19% of the previously treated cases are believed to harbour Drug resistant-TB with an estimated 240 000 deaths annually due to Drug resistant-TB. Ethiopia is among the 30 High TB, HIV and MDR-TB Burden Countries, with annual estimated TB incidence of 177/100,000 populations and death rate of 25 per 100,000 populations for 2016. Among the notified TB cases in 2016, 2.7%) of new TB cases and 14% among previously treated TB cases were also estimated to harbour drug resistant TB. Ethiopia has notified 125,836 new TB cases and enrolled 702 drug-resistant TB case in 2016. Although the majority of TB cases has affected the productive age group, 15 100 (12%) cases were reported among children aged under 15 year. HIV co-infection impedes the TB control efforts contributing to around 8% of annually notified TB cases. Ethiopia has successfully achieved the millennium development goals set for TB in 2015. The country’s has expressed its commitment to accelerate the fight to end TB epidemic by 2035 by endorsing the new post-2015 Global “END TB strategy” and has already aligned the National TB Strategic Plan within the framework of National Health Sector Transformation Plan. The National End TB strategy aims to end the TB epidemic by reducing TB related deaths by 95% and by cutting incident TB cases by 90% between 2015 and 2035; and to ensure that no family is burdened with catastrophic expenses due to TB. The strate- gy calls for use of robust TB case finding strategies and use of rapid diagnostic tech- nologies to address the gap in finding the missed TB cases and threat of Drug resis- tant TB. The program is committed to improve access and equitable TB services to vulnerable and marginalized population groups where TB burden concentrates and most delays happen due to socio-economic and legal barriers. The program has also recognized the need for research and innovations to sharply bend the TB epidemic curve to meet the ambitious targets for 2035. This guideline expresses the strong governmental commitment by introducing the most up-to-date National strategies, recommendations, clinical and programmatic
