This brief update on tuberculosis (TB) in the African region covers the state of TB in the WHO African region, strategic priorities and targets and the impact of COVID-19 on essential services. This is followed by key figures for the region, the role of WHO in country support and, recognizing the im...portance of diagnosis and drug susceptibility testing, a focus onstrengthening laboratory networks and the regional laboratory and diagnostic objectives. A brief update of the state of the science and how this is funded across the African region is provided, before closing with challenges and opportunities,strategic directions and a brief discussion of funding concerns. Discussions around the drivers of the disease, and issues of the poverty, inequality and stigma that continue to plague those living with TB are fully recognized, but are outside the scope of this report.

It summarizes guidance on how to manage – and when to refer – children and adolescents presenting with common complaints and conditions. It includes information to enable primary health care providers to coordinate the continued care of children and adolescents with long-term conditions and dise...ases managed by specialists. Preventive and promotive measures from the newborn period to adolescence include advice on the timing and content of well-child visits, the promotion of early childhood development and health messages for adolescents.
This Pocket Book aims to improve the diagnosis and management of common conditions in children and adolescents that can be managed at the outpatient level. It helps to improve the use of laboratory and other diagnostic measures and the rational use of essential drugs and equipment.

This study, conducted by Tudu et al. (2020), explores the clinical characteristics and outcomes of patients with concurrent malaria and HIV infection, a combination that is relatively understudied in India. The research was carried out at the Department of Medicine, VIMSAR, Odisha, over a one-year p...eriod and included patients who presented with fever lasting up to seven days. Out of 340 patients diagnosed with malaria, 52 (15.29%) were found to also be HIV-positive.
The patients were divided into three groups: Group A with malaria and HIV co-infection, Group B with HIV mono-infection, and Group C with malaria mono-infection. The clinical presentation in co-infected patients resembled that of HIV more closely than malaria. Common symptoms in the co-infected group included fever (82.7%), vomiting (72.3%), anemia (72.3%), headache (65.4%), and aspiration pneumonia (57.7%). Laboratory findings revealed that a significant number of co-infected patients had hemoglobin levels below 7 g/dL and CD4 cell counts under 200 cells/μL, indicating advanced immunosuppression.
All patients received antimalarial treatment with injectable artesunate and antiretroviral therapy (ART). Despite appropriate treatment, the outcome for co-infected patients was comparatively worse: while 48 out of 52 recovered, 6 patients died, mainly due to complications such as anemia, acute kidney injury, and aspiration pneumonia.
In conclusion, the study highlights that although malaria-HIV co-infection is not highly prevalent, it is associated with severe clinical outcomes. Routine screening for both infections in febrile patients is recommended to ensure timely diagnosis and treatment.

The Alere Filariasis Test Strip (FTS) is a rapid diagnostic test recommended for mapping, monitoring and transmission assessment surveys (TAS) for the qualitative detection of Wuchereria bancrofti antigen in human blood samples. The FTS has replaced the Binax Now filariasis immunochromatographic tes...t (ICT), which also detects the same antigen in blood samples. The Brugia Rapid point-of-care cassette test (BRT) manufactured by Reszon Diagnostics is recommended for use during TAS to detect IgG4 antibody against Brugia spp. in human blood samples.
Read the Filariasis Test Strip (FTS) Bench Aid. This bench aid provides detailed instruction on the proper use of the new Filariasis Test Strip used for the detection of Wuchereria bancrofti antigen.

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.

The latest operational handbook includes the new classes recommended by WHO. It aims at facilitating the implementation of the WHO recommendations by the Member States, technical partners, and ot...hers involved in managing patients with TB and DR-TB. The operational handbook provides practical information on existing and new tests recommended by WHO, step-by-step advice on implementing and scale-up testing to achieve local and national impact and lastly, model diagnostic algorithms, which are updated to incorporate the latest recommendations. An overview of budgetary considerations and information sheets on each of the newly recommended tests is provided.

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.
