RESUMO
In this multi-centric cross-sectional survey conducted in nursing homes of the French Alps, from 1 March to 31 May 2020, we analyze the relationship between the occurrence of an outbreak of COVID 19 among residents and staff members. Out of 225 eligible nursing homes, 74 (32.8%) completed the survey. Among 5891 residents, the incidence of confirmed or probable COVID-19 was 8.2% (95CI, 7.5% to 8.9%), and 22 (29.7%) facilities had an outbreak with at least 3 cases. Among the 4652 staff members, the incidence of confirmed or probable COVID-19 was 6.3% (95CI, 5.6% to 7.1%). A strong positive correlation existed between residents and staff members for both numbers of cases (r2 = 0.77, p < 0.001) and the incidence (r2 = 0.76, p < 0.001). In univariate analyses, cases among the staff were the only factor associated with the occurrence of an outbreak among residents (OR = 11.2 (95CI, 2.25 to 53.6)). In bivariate analysis, this relationship was not influenced by any nursing home characteristics, nor the action they implemented to mitigate the COVID-19 crisis. Staff members were, therefore, likely to be a source of contamination and spread of COVID-19 among nursing home residents during the first wave of the pandemic.
RESUMO
BACKGROUND: After Bacillus cereus recovery in opened boxes of disposable gloves, the bacteriological contamination of disposable nonsterile gloves kept stored in native packages was investigated prospectively. METHODS: Thirty-six commercially available nonsterile nonpowdered disposable gloves made of latex, vinyl, or nitrile were cultured. RESULTS: A large variety of spore-forming and non-spore-forming bacteria was recovered, including Bacillus cereus and Clostridium perfringens. CONCLUSION: This finding must be taken into consideration for care involving gloves in very immunocompromised patients.
