  abstract = {{B}ackground: {T}he {COVID}-19 epidemic has spread rapidly within aged-care facilities ({ACF}s), where the infection-fatality ratio is high. {I}t is therefore urgent to evaluate the efficiency of infection prevention and control ({IPC}) measures in reducing {SARS}-{C}o{V}-2 transmission. {M}ethods: {W}e analysed the {COVID}-19 outbreaks that took place between {M}arch and {M}ay 2020 in 12 {ACF}s using reverse transcription-polymerase chain reaction ({RT}-{PCR}) and serological tests for {SARS}-{C}o{V}-2 infection. {U}sing maximum-likelihood approaches and generalized linear mixed models, we analysed the proportion of infected residents in {ACF}s and identified covariates associated with the proportion of infected residents. {R}esults: {T}he secondary-attack risk was estimated at 4.1%, suggesting a high efficiency of the {IPC} measures implemented in the region. {M}ask wearing and the establishment of {COVID}-19 zones for infected residents were the two main covariates associated with lower secondary-attack risks. {C}onclusions: {W}earing masks and isolating potentially infected residents appear to be associated with a more limited spread of {SARS}-{C}o{V}-2 in {ACF}s.},
