Study initiation and follow-up sessions
All information regarding patients’ admission and epidemiological data including age, sex, any past medical history and resent use of immunocompromising medications were documented.
The first follow-up RT-PCR study was performed one month after the initial positive RT-PCR test; at which point all patients had been asymptomatic for at least 14 days. All patients who tested negative were re-tested one and three months after the date of the first follow-up RT-PCR test (Figure-1). A complete assessment of signs and symptoms related to COVID-19 along with serology testing for anti-SARS-CoV-2 IgG and IgM levels were also performed during the 3rdfollow-up visit.
