Wuhan Coronavirus : Key Symptoms Revealed In JAMA Study!

A new JAMA-published study by Dawei Wang et al reveals the key symptoms of patients infected by the Wuhan coronavirus.

Their study will serve as a useful guide for clinicians and public health officials trying to differentiate it from influenza.

 

Wuhan Coronavirus : Key Symptoms!

The highly-anticipated study by Dawei Wang et al, titled Clinical Characteristics of 138 Hospitalized Patients With 2019 Novel Coronavirus-Infected Pneumonia In Wuhan, China was published in The Journal of the American Medical Association (JAMA) on 7 February 2020.

It looked at the clinical characteristics of 138 patients who were hospitalised at the Zhongnan Hospital of Wuhan University, from 1 January to 28 January 2020.

Wuhan Coronavirus : JAMA Study Reveals Key Symptoms!

Top 5 Symptoms Of Wuhan Coronavirus Patients

Their study showed that fever is the chief symptom, and there were very few reports of headache, dizziness, nausea or vomiting.

Dry cough was reported by just over half the patients, and only about ⅓ reported muscle pain. And no one reported a runny or stuffy nose.

This will help to clinically differentiate 2019-nCoV from the far more common influenza.

Here are the top 5 symptoms of the Wuhan coronavirus that the study identified from those 138 patients :

Top 5 Symptoms No. Of Patients % Of Patients
Fever 136 98.6%
Fatigue 96 69.6%
Dry Cough 82 59.4%
Myalgia
(Muscle Pain)
48 34.8%
Dyspnea
(Shortness of Breath)
43 31.2%

Top 5 Symptoms Of Wuhan Coronavirus Patients Requiring ICU Care

Interestingly, they also looked at the symptoms that are more common in patients who ended up requiring ICU care.

They are more likely to lose significant weight and suffer shortness of breath, compared to patients who did not require ICU care.

Here are the top 5 symptoms in patients requiring ICU care. Note that a P value of < 0.05 is considered statistically significant.

Symptoms ICU Non-ICU P Value
Anorexia 66.7% 30.4% < 0.001
Dyspnea
(Shortness of Breath)
63.9% 19.6% < 0.001
Dizziness 22.2% 4.9% 0.007
Pharyngalgia
(Pain in Pharynx)
33.3% 11.8% 0.003
Abdominal Pain 8.3% 0.0% 0.02

Wuhan Coronavirus : What Treatments Did The Chinese Try?

The study also looked at the treatments the Chinese tried with those 138 patients.

While they noted that many patients received antibiotic cover, the key treatments they trialed against the Wuhan coronavirus were Tamiflu (oseltamivir), oxygen support, and glucocorticoid therapy.

Treatment No. Of Patients % Of Patients
Antiviral (Oseltamivir) 124 89.9%
Oxygen 106 76.8%
Glucocorticoid 62 44.9%

Just before the report was released, they did a final follow-up on 3 February 2020, and found that :

  • 47 patients (34.1%) recovered, and had been discharged
  • 85 patients (61.6%) were still hospitalised
  • 6 patients (4.3%) died
