[Detection of a rotavirus G9P[8] outbreak causing gastroenteritis in a geriatric nursing home].
BACKGROUND
The aim of this study was to describe an outbreak of gastroenteritis due to rotavirus in a geriatric nursing home.


METHODS
Stool samples from 8 patients were studied. Antigen detection was carried out by ELISA, and molecular typing was performed by RT-PCR.


RESULTS
Rotavirus antigen was detected in 6 patients. Typing demonstrated a common genotype (G9P[8]).


CONCLUSIONS
The outbreak detected in elderly persons suggests a loss of immunity with age or a lack of protection against an emergent genotype.
