These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

The WHO South-East Asia (SEA) Region bears a high burden of tuberculosis (TB) and MDR-TB. In 2015, the Region accounted for nearly 200 000 or 35% of the global estimated new RR/MDR-TB cases eligible for treatment. Extensively drug-resistant TB (XDRTB) has also been reported from s...ix countries of the SEA Region. MDR-TB could potentially replace drug-susceptible TB, and constitutes a threat to global public health security. The South- East Asia Regional Response Framework for DR-TB 2017–2021 complements the Ending TB in the South-East Asia Region: Regional Strategic Plan 2016–2020” and outlines key strategies for reducing morbidity, mortality and transmission of DR-TB.

In 2014, GHS/NACP, with support from UNICEF and other partners, conducted a situation analysis on paediatric HIV care and treatment in Ghana. The purpose of this analysis was to identify the gaps within the current delivery of paediatric HIV care and support system and develop a road map for effecti...ve implementation of Early Infant Diagnosis (EID) and to increase paediatric antiretroviral therapy (ART) coverage. The analysis identified gaps such as lack of task shifting on ART services, low paediatric ART coverage, and poor linkage of ART, EID, and PMTCT services with other RCH - immunization and nutrition services.
In view of the findings of the analysis, it was recommended that an Acceleration Plan for Paediatric HIV Services be developed to address the barriers and bottlenecks identified during the assessment. At the current pace of paediatric HIV Services, it can be extrapolated that paediatric ART coverage will increase from 26% to only about 40% by 2020; Ghana will, therefore, fall short of the global target of 90-90-90 (UNAIDS concept).

This study, and similar studies in Kenya, Mozambique, Swaziland, Uganda, and Zambia is the outcome of close collaborative by a team in Swaziland, with technical and financial support from the UNAIDS Regional Support Team for Eastern and Southern Africa, UNAIDS Geneva, and the World Bank's Global HIV.../AIDS Program (Global AIDS Monitoring and Evaluation Team). The study entailed using existing data and collecting new data to better know the country's HIV epidemic, know the country HIV response and how funding was allocated, so as to improve the HIV response and strengthen prevention based on evidence on what works to prevent new infections.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.
