“…During the SARS-CoV-2 pandemic, local and national guidelines produced a drastic reduction in visits, with some facilities banning them [ 1 – 4 ]. Visitors could be a reservoir of virus, especially if they are asymptomatic shedders; Paasarelli et al reported two contaminations of inpatients by asymptomatic visitors despite a policy of universal masking [ 1 , 2 – 8 ]. Although the contribution of visitor restrictions to the COVID-19 pandemic has been discussed, the observance of infection control measures (social distancing, mask wearing, hand hygiene) may be imperfect during visits: in the study of Wee et al, the implementation of visitors restrictions was associated to a significant decrease of the cumulative incidence of hospital-associated respiratory viral infections from 9.69 to 0.66 case per 10,000 patient-days [ 9 ].…”

“…The COVID-19 pandemic had tragic consequences in health care facilities (HCFs) and nursing homes; the local spread of the virus inside establishments led to a substantial number of cases and associated deaths [ 1 , 2 ]. Among the infection control measures to prevent the spread of the virus, the limitation and/or suspension of relatives’ visits was implemented in numerous HCFs [ 3 , 4 ].…”

Background During the COVID-19 pandemic, the suspension of relatives’ visits was a common measure in healthcare facilities to prevent the spread of the virus among patients. This measure caused significant adverse consequences for hospitalized patients. Volunteers’ intervention was an alternative but could also lead to cross transmission events. Aims in order to secure their intervention with patients, we implemented an infection control training to evaluate and to improve the knowledge of volunteers about infection control measures. Method We performed a before-after study in a group of five tertiary referral teaching hospitals in the suburbs of Paris. A total of 226 volunteers from three groups (religious representatives, civilian volunteers and users’ representatives) were included. Basic theoretical and practical knowledge about infection control, hand hygiene, and glove and mask use were evaluated just before and immediately after a three-hour training program. The contribution of the characteristics of the volunteers to the results was studied. Findings The initial conformity rate for theoretical and practical infection control measures ranged from 53% to 68%, depending on the participants’ activity status and education level. Some critical shortcomings in hand hygiene as well as mask and glove wearing putatively endangered the patients and volunteers. Surprisingly, serious gaps were also identified among volunteers who experienced care activities. Regardless of their origin, the program significantly improved both their theoretical and practical knowledge (p<0.001). Real-life observance and long-term sustainability should be monitored. Conclusions To become a secure alternative to relatives’ visits, volunteers’ interventions must be preceded by the assessment of their theoretical knowledge and practical skills in infection control. Additional study, including practice audit, must confirm the implementation of the acquired knowledge in the real-life.

Furthermore, the occurrence of nosocomial COVID-19 clusters is reportedly closely associated with the increased trend in COVID-19 community incidence (1)(2)(3).…”

Objective Patients with hematological malignancies and solid organ tumors reportedly tend to have a more severe COVID-19 trajectory than do those with other diseases. We studied the clinical features and outcomes of nosocomial SARS-CoV-2 infection during the seventh wave of the pandemic. Methods This study retrospectively described the characteristics of COVID-19 clusters involving patients in the hematology/respirology ward of Kochi Medical School Hospital during the seventh wave of the pandemic of SARS-CoV-2. Patients and Materials A total of 40 individuals, including 25 patients and 15 healthcare workers, were studied. The diagnosis of SARS-CoV-2 infection was based on reverse transcription polymerase chain reaction performed on nasopharyngeal samples. Results Eleven patients had hematological diseases, and 14 had respiratory diseases. Most patients presented with a fever (n = 19) and/or sore throat (n = 10). Lower respiratory tract symptoms and pneumonia were rather infrequent, occurring in two patients. All patients received antivirals. The maximal severities were mild in 21 patients and moderate in 2. Two asymptomatic patients with SARS-CoV-2 infection did not develop symptoms of COVID-19. Cycle threshold values in nasopharyngeal samples were significantly lower in patients with COVID-19 than in those who were asymptomatic at the time of the diagnosis with SARS-CoV-2 infection. All SARS-CoV-2-infected inpatients recovered or did not develop symptoms of COVID-19. Conclusion COVID-19 vaccination, early or preemptive treatment with antivirals, and intrinsic changes in SARS-CoV-2 may have contributed to the more favorable outcomes in our series than in previously reported nosocomial clusters.
