Available evidence demonstrates that direct patient contact and contact with infectious body fluids are the primary modes for Ebola virus transmission, but this is based on a limited number of studies. In this review, the authors address what we know and what ...we do not know about Ebola virus transmission. They also hypothesize that Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.

ECDC Technical Report
In line with ECDC’s recommendations provided in the ’Risk Assessment of HTLV-1/2 transmission by tissue/cell transplantation’ dated 14 March 2012, this Directive replaces the term ‘incidence’ with ‘prevalence’ in the description of endemic areas of HTLV-1/2 i...nfection. According to the new requirements ‘HTLV-1 antibody testing must be performed for donors living in, or originating from high-prevalence areas or with sexual partners originating from those areas or where the donor’s parents originate from those areas’ and this applies to both donors of non-reproductive tissues and cells and reproductive cells.
ECDC contracted experts from the Institut Pasteur in Paris to systematically review the published evidence on the distribution of HTLV-1 infection prevalence throughout the world and to identify high-prevalence countries and areas.

O Plano Nacional de Preparação e Resposta para a doença por novo coronavírus (COVID-19) é uma ferramenta estratégica de preparação e resposta a uma potencial epidemia pelo vírus SARS-CoV-2. Este Plano tem como referencial as orientações da Organização Mundial da Saúde e do Centro Europ...eu de Prevenção e Controlo de Doenças, sendo o documento de referência nacional no que respeita ao planeamento da resposta a COVID-19. Apesar do conhecimento atualmente disponível em relação a características do SARSCoV-2 nomeadamente o seu comportamento patogénico, potencial de transmissibilidade e outros fatores determinantes não estar completo, é útil considerar, para efeitos de implementação de medidas, uma analogia entre a atual epidemia por SARS-CoV-2 e a gripe pandémica. Apesar de desafiantes, estas características tornam ainda mais premente o planeamento estruturado para diferentes cenários nesta emergência de saúde pública.

This article is a preprint and has not been peer-reviewed [what does this mean?]. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.
The growing understanding of how sequence information can contribute to improved public health is driving global investments in sequencing facilities and programmes. The falling cost and complexity of generating GSD provides opportunities for expanding sequencing capacity; however, challenges to wid...espread implementation remain. This document provides policy-makers and stakeholders with guidance on how to maximize the public health benefit of SARS-CoV-2 genomic sequencing activities in the short and long term as the pandemic continues to unfold. Practical considerations for the implementation of a virus genomic sequencing programme and an overview of the public health objectives of genomic sequencing are covered. This guidance focuses on SARS-CoV-2 but is applicable to other pathogens of public health concern.

SK Bioscience Co. Ltd. [COVID-19 Vaccine (ChAdOx1-S [recombinant])]
Serum Institute of India Pvt. Ltd. [COVISHIELD™, ChAdOx1 nCoV-19 Corona Virus Vaccine (Recombinant)]
The ChAdOx1-S/nCoV-19 [recombinant] vaccine is a replication-deficient adenoviral vecto...r vaccine against coronavirus disease 2019 (COVID-19). The vaccine expresses the SARS-CoV-2 spike protein gene, which instructs the host cells to produce the protein of the S-antigen unique to SARS-CoV-2, allowing the body to generate an immune response and to retain that information in memory immune cells. Efficacy shown in clinical trials in participants who received the full series of vaccine (2 doses) irrespective of interval between the doses was 63.1%, based on a median follow-up of 80 days, but tended to be higher when this interval was longer. The data reviewed at this time support the conclusion that the known and potential benefits of ChAdOx1-S/nCoV-19 [recombinant] vaccine outweigh the known and potential risks.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

A erradicação da varíola humana (mpox em inglês) foi certificada em 1980. A varíola símia (mpox em inglês) é endêmica nos países da África Central e Ocidental desde a sua primeira detecção, em 1958. Trata-se de uma zoonose cujos casos geralmente ocorrem perto de florestas tropicais, ond...e diversos animais são portadores do ortopoxvírus causador da doença. A maioria das infecções em seres humanos pelo vírus da varíola símia em países onde a doença é endêmica é resultado de transmissão primária de animais para humanos. A transmissão de pessoa a pessoa pode ocorrer por meio de contato próximo com secreções respiratórias ou lesões cutâneas de uma pessoa infectada ou com objetos recém-contaminados. A transmissão também pode ocorrer através da placenta da mãe para o feto ou por contato direto durante ou após o parto. Até 21 de maio de 2022, 12 países onde não há varíola símia endêmica, em 2 regiões da Organização Mundial da Saúde (OMS), haviam notificado 92 casos confirmados da doença. Até 26 de agosto de 2022, 96 países sem endemicidade, de todas as 6 regiões da OMS, haviam notificado 45.198 casos confirmados de varíola símia, incluindo 6 óbitos. No mesmo período, os países onde a doença é endêmica notificaram 350 casos confirmados e 6 óbitos. Na Região das Américas, 29 países e territórios notificaram 23.479 (48%) casos confirmados e 3 óbitos. Diversos estudos observacionais sobre as vacinas de primeira geração demonstraram que a eficácia da vacinação contra a varíola humana na prevenção da varíola símia é de aproximadamente 85%. Atualmente, as vacinas originais (de primeira geração) contra a varíola humana não estão mais disponíveis.

The key to a lasting world free of all forms of poliovirus lies in rapidly interrupting all remaining endemic transmission of WPV in the endemic areas of Pakistan and Afghanistan. This is the only way to ensure that such strains do not re-emerge globally through international spread. It lays the cor...nerstone for the eventual cessation of all oral polio vaccine use, in order to eliminate the long-term risks associated with variant poliovirus strains, which is the GPEI’s top operational priority. The target for certifying the
world free of all WPV remains end-2026.
