Coronavirus Symptoms (COVID-19)

Last updated: February 29, 4:40 GMT - We will continue to update and improve this page as we gather new information and details.

Reported illnesses have ranged from people with mild symptoms to people being severely ill and dying.

Symptoms can include:

• Fever
• Cough
• Shortness of breath

Typical Symptoms

COVID-19 typically causes flu-like symptoms including a fever and cough.

In some patients - particularly the elderly and others with other chronic health conditions - these symptoms can develop into pneumonia, with chest tightness, chest pain, and shortness of breath.

It seems to start with a 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.

How long do symptoms last?

Using available preliminary data, the Report of the WHO-China Joint Mission published on Feb. 28 by WHO, [5] which is based on 55,924 laboratory confirmed cases, observed the following median time from symptoms onset to clinical recovery:

• mild cases: approximately 2 weeks
• severe or critical disease: 3 - 6 weeks
• time from onset to the development of severe disease (including hypoxia): 1 week

Among patients who have died, the time from symptom onset to outcome ranges from 2 - 8 weeks.

Symptoms observed in hospitalized patients with COVID-19

Below we list the symptoms, with percentages representing the proportion of patients displaying that symptom, as observed in hospitalized patients tested and identified as having laboratory-confirmed COVID-19 infection. These findings refer to hospitalized patients, therefore generally representing serious or critical cases. The majority of cases of COVID-19 (about 80%) is mild.
