Genomic Epidemiology and Transmission Dynamics of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Congregate Healthcare Facilities in Santa Clara County, California.

Background: Outbreaks of SARS-CoV-2 in long-term care facilities (LTCFs) cause significant morbidity and mortality. Mapping viral transmission within and between facilities by combining genomic sequencing with epidemiologic investigations enables targeting infection-control interventions.

Methods: We conducted weekly surveillance of residents and staff in LTCFs in Santa Clara County, California, with ≥1 confirmed COVID-19 case between March and July 2020.

Rotavirus Vaccination Coverage During a Rotavirus Outbreak Resulting in a Fatality at a Subacute Care Facility.

Background: The introduction of rotavirus vaccine in the United States has reduced rotavirus disease burden, but outbreaks still occur. Complete-series rotavirus vaccination coverage is <75% in the United States, and it might be lower among vulnerable populations. We describe here the clinical characteristics and vaccination status of children during a rotavirus outbreak in a pediatric subacute care facility in 2017.

Three Rotavirus Outbreaks in the Postvaccine Era - California, 2017.
