Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

BMJ 2020; 370 doi: https://doi.org/10.1136/bmj.m3026 (Published 11 August 2020)
The BMJ "practice pointer" inlcudes a one-page visual summary of assessment and initial management of patients with persistant symptoms following acute SARS-CoV-2 infection
Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective pack...ages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.

“Continuum of HIV services refers to a comprehensive package of HIV prevention, diagnostic, treatment, care and support services provided for people at risk of HIV infection or living with HIV and their families”
August, 2018
The purpose of this guide is to provide updated clinical guidance on TB/HIV, with an emphasis on diagnostic aspects—including new techniques—as well as current treatment, while maintaining a public health approach. By compiling and consolidating the latest World Health Organization recommendatio...ns on the subject into a single guide, the aim is to create a reference and consultation document that is frequently used, and that unifies and standardizes the comprehensive management of TB/HIV co-infection in healthcare facilities based on the principle of “two diseases, one patient.” It also seeks to support the updating of national standards and guidelines on co-infection and to complement the coordinated work that must exist between TB and HIV prevention and control programs at all levels, within the framework of the twelve internationally recommended TB/HIV collaborative activities.

Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. In the mid-late 1800s,... the introduction of mechanized tools in the mining sector rapidly increased levels of silica exposure, resulting in an increase in cases and our understanding of silicosis.

This document has been prepared based on the evidence currently available about
Coronavirus disease 2019 (COVID-19) transmission (human-to-human transmission via respiratory droplets or direct contact from an infected individual).
It is recommended to use it in conjunction with the published World... Health Organization
(WHO) Handbook for management of public health events on board ships.
The target audience of this documents is any authority involved in public health response to
a COVID-19 public health event on board ships, including International Health Regulations
(IHR) National Focal Point (NFP), port health authorities, local, provincial and national health
surveillance and response system, as well as port operators and ship operators

This checklist helps to identify the necessary measures to be implemented to mitigate infection transmission among travellers and ground-crossing staff in the context of the COVID-19 pandemic. It features key questions and considerations for gauging the capacity of responding to COVID-19 transmissio...n risks and informing on reducing them at and around ground crossings. It does so in the form of a structured questionnaire. The guidance will have particular relevance for National International Health Regulations Focal Points and competent authorities at the point of entry, including relevant representatives of ground crossing authority/ies of the country such as public health authorities, and representatives from other sectors, including law enforcement, customs and migration.

CDC has developed this slide set for use by staff development, infection control, and occupational health personnel for training healthcare personnel on how to select and use personal protective equipment PPE to protect themselves from exposure to microbiological hazards in the healthcare setting
The document "Priority medical devices list for the COVID-19 response and associated technical specifications" complements this guideline.
This document provides interim guidance on the quality, performance characteristics and related standards of personal protective equipment (PPE) to be used i...n the context of COVID-19. This includes WHO Priority Medical Devices, specifically: surgical masks, non-surgical masks, gloves, googles, face shields, gowns and N95 masks. It is intended for procurement agencies, occupational health departments, infection prevention and control departments or focal points, health facility administrators, biomedical and materials engineering, PPE manufacturers and public health authorities at both national and facility levels.

Health workers are at the front line of the COVID-19 outbreak response and as such are exposed to hazards that put them at risk of infection. Hazards include pathogen exposure, long working hours, psychological distress, fatigue, occupational burnout, stigma, and physical and psychological violence.... This document highlights the rights and responsibilities of health workers, including the specific measures needed to protect occupational safety and health.

In December 2019 a novel coronavirus (2019-nCoV) was identified as the causative agent of a severe acute respiratory illness among people exposed in a seafood market in Wuhan, China; • Human-to-human transmission has been documented, including in healthcare workers, and aerosol-generating procedur...es (AGP)† may play a role in the spread of the disease; • There are uncertainties in the natural history of the 2019-nCoV, including source(s), transmissibility mechanisms, viral shedding, and persistence of the virus in the environment and on fomites; • As of 6 February 2020, the following precautions are recommended for the care of patients with suspected or confirmed cases of 2019-nCoV: o For any suspected or confirmed cases of 2019-nCoV: standard + contact + droplet precautions o For any suspected or confirmed cases of 2019-nCoV and AGP: standard + contact + airborne precautions • The use of personal protective equipment (PPE) by healthcare workers requires an evaluation of the risk related to healthcare-related activities;

Actualités et réflexions sur la prise en charge médicale du premier patient suspect d’infection par le premier médecin
Março de 2020
O número de Estados Membros da União Africana a reportarem
casos do COVID-19 está a aumentar e existe uma probabilidade de transmissão comunitária. A OMS modificou recentemente a definição
de caso suspeito do COVID-19, de modo a incluir infecção respiratória aguda grave... e aconselha a testagem de todos os casos de doença respiratória aguda grave (SARI).1 Contudo, muitos Estados Membros ainda não começaram a implementar estas alterações, pois ainda estão a concentrar os esforços na vigilância de indivíduos com histórico de viagem para uma área com transmissão local do COVID-19. Isto significa que os doentes com sintomas semelhantes, mas sem contacto aparente, podem não ser investigados.
