ASYMPTOMATIC COVID-19 QUARANTINE DIGITAL SOLUTION: A PROOF-OF-CONCEPT
STUDY
10

CASE DEFINITIONS

Confirmed COVID-19 : Positive result on high-throughput sequencing or real-time reverse
2
transcriptase–polymerase chain reaction (rRT-PCR) assay of nasal and pharyngeal swab
specimens.

2
Asymptomatic COVID-19 : Patients with positive rRT-PCR for SARS-CoV-2 and devoid of
any symptoms that would indicate SARS-CoV-2 infection throughout the course of infection
until negative rRT-PCR is obtained at day 10 from admission.

2
Pre-symptomatic COVID-19 : Positive rRT-PCR for SARS-CoV-2 and lack symptoms
indicating SARS-CoV-2 during hospital admission, however develop symptoms later.

Symptomatic COVID-19 : Positive rRT-PCR for SARS-CoV-2 patients who develop
2
symptoms characteristic of COVID-19 prior or at the time of hospital admission.

2
Person-under-investigation for COVID-19 (PUI) : Acute respiratory infection (sudden onset
of respiratory infection with at least one of: shortness of breath, cough or sore throat) with or
without fever

AND

Travelled to / resided in foreign country within 14 days before the onset of illness OR
