Table 1.

Characteristics of hospitalised patients without CoVID-19 symptoms admitted to the EHC Emergency Department between 4/12/2020 and 04/01/2021

Subjects characteristics Patients without CoVID-19 symptoms (n = 116)
SARS-CoV-2-positive RAT (n = 4) SARS-CoV-2-negative RAT (n = 112)
Gender
 Female 2 (50%) 61 (54.5%)
 Male 2 (50%) 51 (45.5%)
Age
 Median [IQR], years 41.9 [30.7-61.2] 46.7 [35.3-69.6]
SARS-CoV-2 RT-PCR result
 Negative 2 (50%)a 107 (95.5%)
 Positive 2 (50%) 5 (4.5%)
Viral load
 Median [IQR], cp/ml 1.8e+08 [1.8e+08 - 1.8e+08]b 1.9e+04 [6.2e+03 - 8e+05]

RAT, rapid diagnostic testing; RT-PCR, reverse transcriptase polymerase chain reaction; IQR, interquartile range; Cp/ml, viral copies per millilitre.

a

Among 4 positive RAT results, 2 were false-positive results, not confirmed by RT-PCR. In this setting, RAT detected less than one third (2/7, 28.6%) of asymptomatic hospitalised patients, who resulted positive by RT-PCR.

b

One of 7 RT-PCR-positive patients (also tested positive with RAT) had a iral load at the limit of detection, that was not quantifiable.
