Atypical symptoms, SARS-CoV-2 test results and immunisation rates in 456 residents from eight nursing homes facing a COVID-19 outbreak.

Background: Frail older persons may have an atypical presentation of coronavirus disease 2019 (COVID-19). The value of real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) testing for identifying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nursing homes (NHs) residents is not known.

Objective: To determine whether (i) atypical symptoms may predict rRT-PCR results and (ii) rRT-PCR results may predict immunisation against SARS-CoV-2 in NH residents.

Atypical clinical presentation of COVID-19 infection in residents of a long-term care facility.

Purpose: To assess the magnitude of the infection in residents from-and staff working in-a long-term-care facility (LTCF) 7 days after the identification of one resident with confirmed COVID-19 infection and to assess the clinical presentation of the infected residents.

Methods: All residents and staff members of a LTCF were tested for SARS-CoV-2 by real-time reverse-transcriptase polymerase chain reaction on nasopharyngeal swab. Residents were studied clinically 4 weeks after the first COVID diagnosis.

Efficacy of a Test-Retest Strategy in Residents and Health Care Personnel of a Nursing Home Facing a COVID-19 Outbreak.

Objective: To assess the American Testing Guidance for Nursing Homes (NHs)-updated May 19, 2020-with a new COVID-19 case.

Design: Case investigation.

Setting And Subjects: All 79 residents and 34 health care personnel (HCP) of an NH.
