Coronavirus COVID-19 causes flu-like symptoms.
Most observed symptoms are fever, followed by a dry cough.
After a week, it can lead to shortness of breath, with about 20% of patients requiring hospital treatment.
Notably, the COVID-19 infection rarely seems to cause a runny nose, sneezing, or sore throat (these symptoms have been observed in only about 5% of patients). Sore throat, sneezing, and stuffy nose are most often signs of a cold.
