Background: The outbreak of SARS-CoV-2 lead to a worldwide pandemic which poses substantial challenges to public health. Methods: We enrolled 102 consecutive recovered patients with laboratory-confirmed SARS-CoV-2 infection. Epidemiological and demographic characteristics, temporal dynamic profiles of laboratory tests and findings on chest CT radiography, and clinical outcomes were collected and analyzed. Results: Independent risk factors for prolonged fever, viral RNA shedding or radiologic recovery included age of more than 44 years, female gender, having symptoms of cough and fever, a delay from the symptom onset to hospitalization of more than 3 days, a lower CD4 count of less than 500/mu L on admission, and severe or critical illness in hospitalization. The estimated median time from symptom onset was 6.4 (5.5 -7.4) days to peak viral load, 9.1 (7.9 -10.4) days to afebrile, 8 (6.7 -9.4) days to worst radiologic finding, 12.7 (11.2 -14.3) days to viral RNA negativity, and 26.7 (23.8 -29.9) days to radiologic resolution. This study included the entire cross-section of patients seen in our clinical practice and reflected the real-world situation. Conclusions: These findings provide the rationale for strategies of active symptom monitoring, timing of quarantine and antiviral interventions, and duration of radiologic follow-up in patients with COVID-19.

Purpose: The purpose of this case study is to share the authors’ involvement and observation in adopting online exam as an evaluation tool, in the hope that others may too be able to adapt and circumvent this lockdown period while bringing a more reliable methodological approach in an online exam. Design/methodology/approach: This is a case study that reports the application of an online examination for a year 3 MBBS Professional Exam during the period of lockdown (movement control). This case highlights the conduct of online theory in the form of single best answer multiple choice questions and online practical via objective structured clinical examination, without jeopardizing the integrity of the system, and the measures adapted to mitigate potential academic dishonesty. Findings: The authors’ observation shows that online exam can be conducted in scenario where conventional exam is not possible. Research limitations/implications: This is an observation in a real-life scenario that discusses the purpose and the process. A single study may not be sufficient to relate the reliability and generalizability of the analysis. Practical implications: The practice of social distancing is a hindrance towards traditional classroom teaching. Online exam has promising potential to be the solution to this problem. The authors have demonstrated that an MBBS theory and practical exam can be conducted remotely without any physical contact, without any compromise in achieving the learning objectives within the curriculum. Medical education can proceed with a new drive while ensuring the learning process continues a stable momentum. Originality/value: Online examination is almost unheard of, especially for undergraduates in the medical programme. This study highlights a plausible approach in the design of the online examination and identifies the barriers and favourable edges of this platform. © 2021, Emerald Publishing Limited.
