  abstract = {{B}ackground : {W}orldwide, {COVID}-19 outbreaks in nursing homes have often been sudden and massive. {T}he study investigated the role {SARS}-{C}o{V}-2 virus spread in nearby population plays in introducing the disease in nursing homes. {M}aterial and methods : {T}his was carried out through modelling the occurrences of first cases in each of 943 nursing homes of {A}uvergne-{R}h{\^o}ne-{A}lpes {F}rench {R}egion over the first epidemic wave ({M}arch-{J}uly, 2020). {T}he cumulative probabilities of {COVID}-19 outbreak in the nursing homes and those of hospitalization for the disease in the population were modelled in each of the twelve {D}{\'e}partements of the {R}egion over period {M}arch-{J}uly 2020. {T}his allowed estimating the duration of the active outbreak period, the dates and heights of the peaks of outbreak probabilities in nursing homes, and the dates and heights of the peaks of hospitalization probabilities in the population. {S}pearman coefficient estimated the correlation between the two peak series. {R}esults : {T}he cumulative proportion of nursing homes with {COVID}-19 outbreaks was 52% (490/943; range: 22-70% acc. {D}{\'e}partement). {T}he active outbreak period in the nursing homes lasted 11 to 21 days (acc. {D}{\'e}partement) and ended before lockdown end. {S}pearman correlation between outbreak probability peaks in nursing homes and hospitalization probability peaks in the population (surrogate of the incidence peaks) was estimated at 0.71 (95% {CI}: [0.66; 0.78]). {C}onclusion : {T}he modelling highlighted a strong correlation between the outbreak in nursing homes and the external pressure of the disease. {I}t indicated that avoiding disease outbreaks in nursing homes requires a tight control of virus spread in the surrounding populations.},
