Key symptoms, biochemical and radiological features of the clinical course of COVID-19.

The time period between contact and therefore the first set of symptoms is typically 1–14 days (but up to 24 days in individual cases). The median time between registered exposure and first symptoms is 5.1 days with a mean of 6.1 days. Duration of viral supermolecule shedding ranges between 8 to 34 days (median 20 days) after the initial symptoms. The main clinical symptoms develop within 11.5 days (95% confidence interval (CI) 8.2-15.6 days) and include fever, dry cough, fatigue, ageusia, anosmia, and headache. Other non-specific symptoms have also been reported, including nasal congestion, rhinorrhea, pharyngitis, myalgia, poor appetite, and diarrhoea. Fever and cough typically appear concomitantly, followed by shortness of breath and severe fatigue, which appear around 6-76 day and are related to the development of severe bilateral (and occasional unilateral) pneumonia.
