Not just dry cough and later fever,

Sample quote

Nearly half of COVID-19 patients enrolled in the study conducted in the Hubei province of China presented digestive symptoms,
such as diarrhea and anorexia, and cited it as their chief complaint.
The study also reveals that patients with digestive symptoms had a longer gap between the onset of symptoms and hospital admission than patients presenting only respiratory symptoms and were less likely to be cured and discharged than those without digestive symptoms.
