Norovirus Outbreaks in Long-term Care Facilities in the United States, 2009–2018: A Decade of Surveillance

Abstract

LTCFs have a high burden of norovirus outbreaks. Most LTCF norovirus outbreaks occurred during winter months and were spread person-to-person. Outbreak surveillance can inform development of interventions for this vulnerable population, such as vaccines targeting GII.4 norovirus strains.
