(*It is important to note that many of the percentages in these early studies will change as more asymptomatic or minimally symptomatic patients are identified with increased testing)
Among more than 44,000 confirmed cases of COVID-19 in China as of Feb 11, 2020:
- 30–69 years: ~78%
- severely or critically ill: ~19%
-60-69 years: 3.6%
-70-79 years: 8%
-≥80 years: 14.8%.
-With no underlying medical conditions: overall case fatality of 0.9%
-cardiovascular disease (10.5%), diabetes (7%)
-chronic respiratory disease, hypertension, and cancer (6% each)
For patients admitted to the hospital, many non-specific signs and symptoms:
- fever (77–98%) and cough (46%–82%) were most common
- of note, gastrointestinal symptoms (~10%) such as diarrhea and nausea present prior to developing fever and lower respiratory tract signs and symptoms.
No general lab tests have great sensitivity or specificity
A normal CT scan does NOT rule out COVID-19 infection
-In an early study, 20/36 (56%) of patients imaged 0-2 days (‘early’) after symptom onset had a normal CT with complete absence of ground-glass opacities and consolidation
Mainstay of treatment will be management of hypoxemia including early intubation if necessary. However, specifically:
-Steroid therapy is controversial and the WHO is currently recommending against it unless it is being administered for another reason
-has not been associated with any benefit
-associated with possible harm in previous smaller studies with SARS and MERS
-associated with prolonged viremia
-intravenous remdesivir (a nucleotide analogue prodrug with promising in-vitro results against SARS-CoV and MERS-CoV) is available for compassionate use
-lopinavir-ritonavir has been used without any associated benefit
