Les données sur les épidémies de maladie nosocomiale à COVID-19 dans les établissements de réadaptation gériatrique sont rares. Dans cette analyse rétrospective de séries de cas, nous décrivons une telle épidémie, déterminons la proportion de patients a-/présymptomatiques, le temps médian avant l’apparition des symptômes chez les patients présymptomatiques et cherchons à savoir si la charge virale diffère entre les patients avec et sans symptômes.
Data about outbreaks of nosocomial COVID-19 disease within geriatric rehabilitation facilities are scarce. In this retrospective case series analysis, we describe such an outbreak, determine the proportion of a-/presymptomatic patients, the median time before symptom onset among presymptomatic patients and investigate whether the viral load differs between patients with and without symptoms. Typical and atypical symptoms were retrieved from the electronic medical records of patients who tested positive for COVID-19 disease during their stay at a 95-bed geriatric rehabilitation facility. The viral load at the time of diagnosis was estimated on cycle threshold values of the rRT-PCR test. Overall, 34 patients (median age, 87 years; range, 66–98; 67% female) tested positive for SARS-CoV-2. During the same period, 19 health care workers were also diagnosed with COVID-19. Among the 27 patients who provided consent, 20 (74%) were symptomatic at the time of testing. Among the remaining seven patients, six developed symptoms after a median of 2 days. A viral load > 106 copies/mL was observed in 20 out of the 27 patients, including five out of the seven initially asymptomatic patients. The rapid transmission of SARS-CoV-2 and the prevalence of initially asymptomatic patients with high viral loads support an extended screening strategy at such facilities.
