    Abstract SARS-CoV-2 mainly infects the respiratory tract, and presents significantly higher active replication in the upper airways. To remain viable and infectious, the SARS-CoV-2 virion must be complete and integral, which is not easily demonstrated in the environment by positive reverse transcriptase PCR results. Real-life conditions in healthcare settings may be conducive to SARS-CoV-2 RNA dissemination in the environment but without evidence of its viability and infectiveness in air. Theoretically, SARS-CoV-2 shedding and dissemination nonetheless appears to be air-mediated, and a distinction between "air" and "droplet" transmission is too schematic to reflect the reality of the respiratory particles emitted by patients, between which a continuum exists. Airborne transmission is influenced by numerous environmental conditions that are not transposable between different viral agents and situations in healthcare settings or in the community. Even though international guidelines on "droplet" versus "air" precautions and personal protective equipment (surgical versus respirator masks) are under discussion, the existing literature underscores the effectiveness of "droplet" precautions as a means of protecting healthcare workers. Differentiation in guidelines between healthcare venues, community settings and, more generally, confined environments is of paramount importance, especially insofar as it underlines the abiding pandemic-related need for systematic mask wearing by the general population.

    Abstract Non-tuberculous mycobacteria (NTM) are opportunistic pathogens commonly colonizing hospital water systems, and may be responsible for healthcare-associated infections (HAI). Investigation of HAI and outbreaks caused by NTM necessitates water analyses. However, NTM are slow-growing bacteria within the mesophilic community present in water, and are difficult to detect. Prior to culture on specific media, their recovery usually requires decontamination and concentration steps. We assessed the effectiveness of filtration as regards the recovery of 7 NTM species in hospital water samples. We also compared the use of cetylpyridinium chloride (CPC) at different concentrations and Sodium Hydroxide (NaOH) 4% in decontamination of water samples with mesophilic bacteria. Our laboratory protocol showed that membrane filtration was suitable for concentration and recovery of NTM from water. Sample decontamination with CPC was more NTM-preservative than NaOH. A combination of CPC at 0.005% and filtration allowed detection of NTM at low concentrations, ranging from 3 to 98 CFU/100mL according to the NTM species.

    Abstract SARS-CoV-2 is mainly transmitted by respiratory droplets and contact with contaminated surfaces. It can be retrieved in faeces but there is no evidence of faecal-oral transmission, which is the main route of contamination in recreational waters. Standard cleaning and disinfecting procedures, microbiological control and health rules aim to prevent infectious risk regardless of the micro-organisms. In the context of progressive lockdown exit and hospital activities recovery, we assessed the risk of SARS-CoV-2 transmission in rehabilitation pools and therapeutic water environments in order to provide specific recommendations to control the spread of SARS-CoV-2 while ensuring essential rehabilitation care for patients.

    Abstract In the context of the recent re-emergence of mpox worldwide, the French Society for Hospital Hygiene (SF2H) performed a literature review of the transmission paths and proposed specific recommendations for healthcare workers (HCWs) caring for patients with suspected or confirmed MPXV. In developed countries, the risk of contamination among HCWs in healthcare facilities seemed to be very low, limited to contamination through needle stick injuries. Two additional contamination cases were reported and not fully explained. Beyond healthcare settings, the analysis of the literature highlighted (i) a main contamination route during sexual intercourse, mainly among men who have sex with men, and (ii) a very low secondary attack rate in other contexts, such as schools or jails. Numerous studies have reported molecular or virus identification on surfaces or in the air surrounding patients, without any association with the low secondary case incidence; moreover, the minimum infectious dose through air or mucosal exposure is still unknown. Owing to the lack of evidence of MPXV respiratory transmission in the healthcare setting, the SF2H recommends the implementation of standard and contact precautions combined with medical/surgical mask use. Owing to the lack of evidence of transcutaneous contamination, the SF2H recommends the use of gloves only if contact with cutaneous lesions or mucous membranes occurs. Regarding the risk of contamination from the environment in healthcare facilities, additional studies must be conducted to investigate this.

    Abstract In the context of the COVID-19 pandemic, wearing a face mask has become usual and ubiquitous, in both hospitals and community. However, the general public is consuming surgical or filtering face piece (FFP) masks irrespective of their specificity, leading to global supply shortage for the most exposed persons, which are healthcare workers. This underlines the urgent need to clarify the indications of the different categories of mask, in order to rationalize their use. The study herein specifies the French position for the rational use of respiratory protective equipment for healthcare workers.
