Improving our response to the ongoing COVID-19 pandemic in Africa requires regularly updated information, constant innovation, and considerable support towards research and development (R&D) for priorities that respond to the African realities. Shaping the research agenda and stimula...ting the generation, translation, and dissemination of valuable knowledge is one of the core functions of the African Academy of Sciences (AAS), African Centre for Disease Control (Africa CDC), and WHO-AFRO. We need answers to a list of critical research questions that respond to the current realities on the African continent to guide the COVID-19 outbreak control efforts

This document synthesizes key elements of the World Health Organization (WHO) normative guidance on health policy and system support for community health worker (CHW) programmes and their application for HIV programmes. Building on relevant elements of HIV guidelines, tools and evidence identified b...y experts, it provides recommendations on tasks and roles that can be performed by CHWs (including for HIV), identifies the policy and system supports to optimize CHW performance, and gives examples of best practice. Its purpose is to inform the optimal design and delivery of CHW programmes targeting – either specifically or as part of a broader approach – the scale-up and sustainability of HIV services.

This module introduces the “Vaccinator’s Manual”, a guideline for vaccinators. The aim of the manual is to update EPI guidelines to include all the changes since the third edition of the Vaccinators Manual (2008)
The roadmap describes the actions needed to
achieve the three development goals for TB
vaccines set by the WHO:
1. A safe, effective and affordable TB vaccine
for adolescents and adults.
2. An affordable TB vaccine for neonates and
infants with improved safety and efficacy.
3. A therapeutic v...accine to improve TB

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

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.

This document provides guidance on interventions to prevent vaccine-preventable disease outbreaks in the context of mass population movement resulting from the ongoing crisis in Ukraine.
Cryptococcal disease, particularly cryptococcal meningitis is a significant cause of morbidity and mortality among people living with HIV with advanced HIV disease. It is estimated that it is responsible for nearly 19% of AIDS-related mortality, second only to tuberculosis. Rapid screening, diagnosi...s and linking to appropriate treatment are critical actions national programs must take to reduce the burden of disease.
WHO in 2022 introduced updated guidelines for diagnosing, preventing, and managing cryptococcal disease among adults, adolescents and children living with HIV. This policy brief provides a summary of the key recommendations, clinical considerations, and also stresses the importance of ensuring access to life-saving antifungals. There is an urgent need for countries to scale-up management for not just cryptococcal meningitis, but address cryptococcal disease in the context of a package of care for advanced HIV disease as recommended by WHO.

Many countries have made significant progress in the implementation of World Health Organization recommended preventive chemotherapy strategy, to eliminate lymphatic filariasis (LF). However, pertinent challenges such as the existence of areas of residual infections in disease endemic districts pose... potential threats to the achievements made. Thus, this study was undertaken to assess the importance of these areas in implementation units (districts) where microfilaria (MF) positive individuals could not be found during the mid-term assessment after three rounds of mass drug administration.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.
