Testing and diagnosis of hepatitis B (HBV) and C (HCV) infection is the gateway for access to both prevention and treatment services, and is a crucial component of an effective response to the hepatitis epidemic. Early identification of persons with chronic HBV or HCV infection enables them to recei...ve the necessary care and treatment to prevent or delay progression of liver disease. Testing also provides an opportunity to link people to interventions to reduce transmission, through counselling on risk behaviours and provision of prevention commodities (such as sterile needles and syringes) and hepatitis B vaccination.

Policy Brief

WHO/CDS/HIV/18.48
Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

HIV testing
Policy Brief
July 2015
Policy brief.
HIV self-testing (HIVST) is a convenient and confidential option for HIV testing. In 2016 WHO recommended HIVST as a safe, accurate and effective way to reach people who may not test otherwise, including people from key populations, men and young people. Lay users can perform HIVST r...eliably and accurately and achieve performance comparable to that of trained health-care workers.
Globally, many countries have developed HIVST policies, and implementation is growing rapidly. This policy brief highlights new guidance to optimize HIVST implementation, including effective service delivery models, linkage to care and support tools.

Efficient triage of patients with COVID-19 at all health facility levels (primary, secondary and tertiary) will help the national response planning and case management system cope with patient influx, direct necessary medical resources to efficiently support the critically ill and protect the safety... of health-care workers. The objective of this algorithm is to give overall guidance for the triage and referral of symptomatic COVID-19 patients. Intended for use by ministries of health, hospital administrators and health workers involved in response planning for COVID-19 and/or patient triage, management and referral, this algorithm provides a general framework to be adapted to local health systems in countries.

This implementation brief addresses integration of HIV testing services into family planning (FP) services. It is intended as a practical resource for national health programmes seeking to introduce or scale up HIV testing and linkage to HIV prevention, sexually transmitted infection, and antiretrov...iral therapy services in FP.
This document highlights emerging good practices and country experiences of integrated HIV prevention and testing services within FP and advocates for increased linkage for FP clients to HIV services according to their needs. It also brings together information on models of integration of HIV testing into FP services, programme examples from east and southern Africa and guidance on the implementation monitoring process.

Tuberculosis (TB) is the deadliest infectious disease in most low- and middle-income countries, claiming more than 4,000 lives each day. The unprecedented COVID-19 pandemic has seriously impacted people with pre-existing health conditions. People with TB are usually more vulnerable to other infectio...ns, including the novel coronavirus, due to pre-existing lung damage. They are also at higher risk of developing complications from COVID-19.

Countries are making progress toward the global goal of 95% of people living with HIV knowing their status by 2025. However, considerable gaps remain in achieving these goals globally. Men in high HIV burden settings and men from key populations in all settings are consistently less likely to know t...heir HIV status than women. Globally, 78% of men ages 15 years and older who are living with HIV are aware of their HIV status, compared with 86% of women with HIV of these ages.
Offering HIV testing services, including HIV self-testing, at formal and informal workplaces has emerged as an effective, acceptable and feasible approach for reaching men. A 2018 World Health Organization (WHO) and International Labour Organization (ILO) policy brief provides key guiding principles for HIVST implementation at workplaces. Building on the 2018 policy brief, this brief captures early experience with HIVST implementation at workplaces and discusses emerging approaches of sustainable financing that can be adapted for HIV self-testing at workplaces.
The primary audiences for this policy brief are ministries of health and labour, national HIV programmes, employers’ organizations, workers’ organizations (labour unions), enterprises, implementing partners, including civil society organizations, and health insurance agencies.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.
