Review[French research organization on emerging infectious diseases: from REACTing to ANRS Emerging Infectious Diseases].
Emerging infectious diseases (EIDs) can be responsible for epidemics or even pandemics that disrupt societies and cause national and international crises. In our globalized world, anarchic urbanization, ecosystem disruptions (deforestation, creation of dams…), changes in crop and livestock farming conditions, the increasing availability of air transport, population displacement and climate change are all factors that favor the occurrence and spread of emerging or re-emerging pathogens such as SARS-Cov, MERS-CoV, Ebola, Zika, influenza, or more recently SARS-CoV-2 and Monkeypox. States, regional and international organizations, health and research agencies, non-governmental organizations and the pharmaceutical industry are today challenged by the repetition of these crises and their consequences on health, social, economic and political balances. ⋯ This new regime calls for new responses, to meet in the urgency the challenges of emergency epidemic crises and to better respond to the issues of crisis management in a context of "One Health". Research is an essential pillar in the response to these epidemics with a double challenge: (i) to improve knowledge on the disease, its prevention, treatment, diagnosis, impact on society. and (ii) to prepare for and understand future emergencies, "anticipate". As epidemics have occurred over the last fifteen years, French research has been organized and has evolved to respond to these crises, from the genesis of REACTing in 2011, to the creation of the ANRS Emerging Infectious Diseases in 2021.

Review[Cell senescence, a new target for respiratory viral infections: From influenza virus to SARS-CoV-2].
The accumulation of senescent cells in tissues is a key process of aging and age-related diseases, including lung diseases such as chronic obstructive pulmonary disease, lung fibrosis, or cancer. In recent years, the spectrum of respiratory diseases associated with cellular senescence has been broadened, in particular acute viral pulmonary infections, foremost among which is coronavirus disease 2019 (COVID19), which is particularly severe in the elderly or in subjects with comorbidities. ⋯ Cellular senescence potentially represents an original target for attacking these diseases, although its specific mechanisms remain largely misunderstood. New anti-senescent therapeutic approaches are thus proposed during severe viral pulmonary infections, with the aim of preventing acute effects and/or, in the longer term, pulmonary sequelae.

[Impact of the first year of the COVID-19 pandemic on the epidemiology of invasive infections (bacteremia) in the hospitals of the Assistance Publique - Hôpitaux de Paris].
The COVID-19 pandemic has led to a massive influx of patients suffering from severe forms of the disease into hospitals, often requiring intensive care (vascular catheters, ventilation, etc.) which exposes them to high risks of nosocomial infections, particularly invasive infections (bacteremia). ⋯ The COVID-19 pandemic which had a strong impact on hospital management and social organization in the general population, had opposite impacts on the incidence of bacteremia depending on the pathogens and their mode of transmission.

This work aimed to assess the impact of COVID-19 on healthcare supply in sub-Saharan Africa except South Africa. ⋯ Several articles make recommendations aimed at reducing the impact of future epidemics: support for community workers, training of health workers and reorganization of services to improve the reception and care of patients, technological innovations (use of telephones, drones, etc.) and better information monitoring.
