Typical Symptoms of Coronavirus
COVID-19 usually causes flu like symptoms including fever, sore throat and cough.
In some patients, particularly the elderly and some others with other chronic health conditions, these symptoms can take the form of pneumonia. They can also experience it with chest tightness, chest pain, and shortness of breath.
COVID-19 symptoms seems to start with a fever, followed by a dry cough.
After a week of experiencing the first symptoms, it can lead to shortness of breath, with about 20% of patients requiring hospital treatment and care.
Notably, the COVID-19 infection rarely seems to cause a runny nose, sneezing, or sore throat. Sore throat, sneezing, and stuffy nose are most often signs of a cold rather than Coronavirus.
80% of Coronavirus Cases are Mild
Based on all of 72,315 cases of COVID-19 confirmed, suspected, and asymptomatic cases in China as of February 11, 2020, a paper was released by the Chinese CCDC on February 17, 2020. It was published in the Chinese Journal of Epidemiology. The paper concluded that:
- 80.9% of infections are mild (with flu-like symptoms) and can recover at home itself.
- 13.8% are severe, developing severe diseases including pneumonia and shortness of breath.
- 4.7% are critical and can include: respiratory failure, septic shock, and multi-organ failure.
- in about 2% of reported cases the Corona virus is fatal.
- Risk of death is high for the older people.
- Relatively very few cases are seen among children or young people.
Pre-existing Conditions of patients
Pre-existing illnesses that can put a patient at a higher risk are:
- cardiovascular disease
- chronic respiratory
That said, some healthy people also do seem to develop a severe form of pneumonia after being infected by the Corona virus. Doctors are trying to investigate what could be the common parameter or condition as they try to learn more about this new virus(COVID-19).
Examples of Development of Symptoms in some patients (from actual cases):
A man in his 40s in Japan:
- Day #1: malaise and muscle pain
- later diagnosed with pneumonia
A man in his 60s in Japan:
- Day #1: initial symptoms of low fever and sore throat
A man in his 40s in Japan:
- Day #1: fever, chills, sweating and malaise
- Day #4: fever, muscle pain and cough
A woman in her 70s, in Japan:
- Day #1: 38° C fever for a few minutes
- Day #2,3: went on a bus tour
- Day #5: visited a medical institution in Japan
- Day #6: later showed symptoms of pneumonia.
A woman in her 40s, in Japan:

- Day #6: being treated at home in isolation

- Day #1: Cold
- Day #6: Fever of 39° C
- Day #8: Pneumonia
Another patient, in China with a history of type 2 diabetes and hypertension:
- Jan. 22: Fever and cough
- Feb. 5: Died
First death in the Philippines (a 44-year-old Chinese thought to have had other pre-existing health conditions):
- Jan. 25: Fever, cough, and sore throat, he was hospitalized
- Developed severe pneumonia
- Feb. 2: Died
How long do the symptoms for the Coronavirus last?
The Report of the WHO-China Joint Mission published on February 28, 2020 by WHO, which is based on 55,924 laboratory confirmed cases over the globe, observed the following median time from symptoms onset to clinical recovery in patient cases:
- 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 Coronavirus
Below are the list of symptoms, with percentages showing the proportion of patients displaying that symptom, as observed in hospitalized patients tested and identified as having laboratory confirmed Corona Virus infection. These findings refer to serious or critical cases only. The majority of Coronavirus cases (about 80%) is mild.
According to the Wang et al study published on JAMA and also based on 138 hospitalized patients.
|Common symptoms included:|
The median time observed:
- from first symptom to → Dyspnea (Shortness of breath) = 5.0 days
- from first symptom to → Hospital admission = 7.0 days
- from first symptom to → ARDS (Acute Respiratory Distress Syndrome) = 8.0 days (when occurring)
