A coronavirus disease 2019 outbreak in a residential living facility with suboptimal ventilation in resident rooms.

We report a large outbreak of SARS-CoV-2 in a residential living facility. Measurements of carbon dioxide levels, aerosol particle clearance, and airflow were used to identify and remediate areas with suboptimal ventilation. A simple intervention involving continuous operation of bathroom fans was effective in significantly improving ventilation in resident rooms.

Containment of COVID-19 outbreak at a veterans affairs community living center.

Asymptomatic and pre-symptomatic staff and residents likely contribute to widespread transmission of COVID-19 in long-term care settings. Here, we describe the successful containment of a COVID-19 outbreak on one floor of a 163-bed Veterans Affairs (VA) Community Living Center (CLC). Testing using nasopharyngeal swabs with a rapid turn-around-time identified 3 of 28 (11%) residents and 2 of 41 (5%) healthcare personnel (HCP) with COVID-19. Both HCP likely worked on the floor while pre-symptomatic. When one HCP reported a cough to the secondary (employee) screening clinic, she was erroneously advised to work. Protocols to limit the risk for HCP to import COVID-19 were reinforced with Community Living Center staff as well as with personnel in secondary screening. Further, the CLC implemented an expanded screening tool that assessed residents for typical and atypical symptoms of COVID-19. No further cases of COVID-19 were detected on the CLC floor in the subsequent 6 weeks. Swift recognition and response helped contain the outbreak and prevent further COVID-19 infections among other residents and staff.

Bacterial urine profile and optimal urine specimen collection timing in asymptomatic chronically catheterized adults with spinal cord injuries and disorders.

BACKGROUND: Adults with spinal cord injuries and disorders (SCI/D) require chronic indwelling catheterization which is associated with an increased risk of catheter-associated (CA) adverse events. METHODS: We studied urine samples (culture and urinalysis) from 2 cohorts of chronically catheterized males with SCI/D. Cohort 1 included 28 participants; 3 samples per patient were collected (before, after, and 7 days after catheter change). Cohort 2 included 21 participants; 7 samples per patient were collected (before, immediately after, 30 minutes, 1 hour, 1 day, 2 days, and 7 days after catheter change). RESULTS: A statistically significant decrease in the post catheter change percentage of "significant cultures" was found in both our cohorts (P<.05). Additionally, our second cohort demonstrated a significant decrease in the number of organisms growing at 100.000 cfu/mL (median=-1, mean=-1.5, P=.0006) and in urinalysis bacterial numbers (median=-0.5, mean=-1, P=.006) from pre- to 1-hour post catheter removal. CONCLUSIONS: Although there appears to be an improvement of organism burden seen after catheter change, this is only temporary, and its significance in chronically catheterized patients is still unknown. Our second cohort demonstrated an optimal time for sample collection at the 1-hour post-catheter change sample, but further research is required for the extrapolation of these findings.
