The purpose of this work is to estimate potential COVID-19 case burdens in each African nation considering various social distancing interventions. Given current trends in case burden, the model estimates the potential resource needs that would be needed under different scenarios. The model is for p...lanning purposes and is based on current understanding and the most up-to-date assumptions. Results reported here are not forecasts but scenarios that may unfold given the assumptions about social-distancing and population health.
You can download scenarios for North Africa; Middle Africa; West Africa, East Africa and South Africa

The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and ...its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels.

The use of safe and efficacious insecticides against the adult and larval populations of mosquito vectors is one of the most effective ways to rapidly interrupt transmission of Zika virus, as well as other viruses transmitted by Aedes mosquitoes such as chikungunya and dengue.
PHSM are vital in reducing the risk and scale of infectious disease transmission and lowering hospitalization and deaths. Examples include contact tracing, quarantine and isolation, mask use, ventilation, school or workplace measures, mobility restrictions and travel requirements.
While these mea...sures are essential, decision-making on PHSM becomes particularly complex during rapidly evolving health emergencies, with incomplete information and under significant public and political pressure, especially when the pathogen is novel or poorly understood. In such contexts, guidance needs to be agile and responsive, developed and adapted based on emerging evidence and shifting epidemiological patterns. Decision-makers are frequently confronted with difficult trade-offs, having to balance measures that are:
─ effective but socially disruptive;
─ cost-effective but logistically burdensome;
─ beneficial for public health but economically disruptive; or
─ practical but inequitable or unethical

n light of the potential risk posed by SARS-CoV-2 variants, in January 2021 WHO organized an ad hoc consultation to discuss the development of an R&D agenda in response to existing and emerging SARS-CoV-2 variants.
The key objectives were to identify the critical research questions related to var...iants and agree on a research approach to address them. Six breakout groups covered a range of specific issues related to COVID-19 variants: Epidemiology and mathematical modelling; evolutionary biology; animal models; assays and diagnostics; clinical management and therapeutics; and vaccines.

Modelling the health impacts of disruptions to essential health services during COVID-19 Module 1
Several epidemiological models have been created to assess the potential impact of disruptions to essential health services caused by COVID-19 on morbidity and mortality from conditions other than COVI...D-19 illness. This guide presents models that have been used to assess these indirect impacts. The effects have been studied in various settings, using a variety of models.
The guide is intended for people who need to understand what the models say, their construction and their underlying assumptions, or need to use models and their outcomes for planning and programme development and to support policy decisions for a country or region.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

Review of International, Regional and National Policies and Legal Frameworks that Promote Migrants and Mobile Populations' Access to Health and Malaria Services in the Greater Mekong Subregion (Cambodia, Lao People's Democratic Republic, Myanmar, Thailand and Viet Nam)
Migrants and mobile popul...ations face many obstacles in accessing equitable essential health care services due to factors such as living and working conditions, education level, gender, irregular migration status, language and cultural barriers, anti-migrant sentiments, and lack of migrant-inclusive health policies among others. Despite significant progress having been made in the context of malaria control in the Greater Mekong Subregion (GMS), human movements can impact malaria transmission patterns and potentially introduce drug-resistant parasites. This legal framework review therefore serves as a guidance document on approaches to address malaria and malaria elimination for migrant and mobile populations (MMPs) in five countries of the GMS.

This document provides interim recommendations for the surveillance of Zika virus infection, microcephaly and Guillain-Barré syndrome, in four different contexts and describes reporting requirements to WHO. Transmission refers to vector-borne transmission, unless specified differently. Autochthonou...s infection is considered to be an infection acquired in-country, i.e. among patients with no history of travel during the incubation period or who have travelled exclusively to non-affected areas during the incubation period. This document does not provide guidance on laboratory investigation or vector surveillance.
