Note d'orientation 7 juin 2022.
Ce document a pour but d'encourager les pays à élaborer et à mettre en œuvre des politiques visant à maintenir et à renforcer les programmes et mesures de prévention des infections dans les établissements de soins de santé dans le contexte de la transmission... actuelle du SRAS-CoV-2, tout en reconnaissant que les tendances épidémiologiques peuvent varier et que le risque de transmission d'autres agents pathogènes existe.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

The World Health Organization provides regional and national strategies and operational plans that aim to support countries in work to achieve measles control and elimination. These are guided by high level frameworks including the Immunization Agenda 2030 and the Measles and Rubella Strategic Frame...work 2021–2030. These frameworks promote improvements in routine immunization programmes to reach all children, reduce immunity gaps and prevent outbreaks within the context of universal health care.
This interim guidance on Targeted and selective strategies in measles and rubella vaccination campaigns adds to the suite of guidance documents. It provides expanded description of methods to determine age groups for inclusion in preventive and outbreak response measles and rubella vaccination campaigns; and operational considerations that are specific to targeted and selective strategies in measles and rubella vaccination campaigns. This guidance also updates definitions for tailored, targeted and selective campaigns.The World Health Organization provides regional and national strategies and operational plans that aim to support countries in work to achieve measles control and elimination.

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.

Standard precautions aim to protect both health workers and patients by reducing the risk of transmission of microorganisms from both recognized and unrecognized sources. They are the minimum standard of infection prevention and control practices that should be used by all health-care workers, durin...g the care of all patients, at all times, in all settings. When applied consistently, standard precautions can prevent the transmission of microorganisms between patients, health workers and the environment. This aide-memoire presents a concise overview of important advice for implementation and key elements at a glance.

This practical manual is designed to support implementation of the World Health Organization (WHO) Guidelines on core components of infection prevention and control programmes at the national level, with special focus on countries with limited resources.
The Guidelines describe what is necessary ...(that is, recommendations) to effectively improve infection prevention and control (IPC). This practical manual outlines how to do this (that is, how to implement the Guidelines). It focuses on the development of a sustainable action plan informed by the local context to put into operation the Guideline recommendation

Health care-associated infections (HAI) are one of the most common adverse events in care delivery and a major public health problem with an impact on morbidity, mortality and quality of life. At any one time, up to 7% of patients in developed and 10% in developing countries will acquire at least on...e HAI. These infections also present a significant economic burden at the societal level. However, a large percentage are preventable through effective infection prevention and control (IPC) measures.

IPCAT2 will assist countries to determine the core components already in place, that is, existing strengths, and to identify gaps or weaknesses to guide action planning. IPCAT2 corresponds to the six core component recommendations of the guidelines targeted at the national level.
It is very impor...tant to understand that IPCAT2 is not intended to be used as an audit tool. Its purpose is to help assess, plan, organize and implement a national IPC programme. The tool provides a general overview of the status of IPC activities according to the guideline recommendations, rather than focusing on specific IPC practices/risk factors related to individual patients or specific.
