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.
