Clinical Presentation
It was notably interesting that approximately one-fourth of the patients
were asymptomatic (23.8% with 95% CI, 17.6-31.2%). Amongst the
symptomatic, fever (52.5% with 95% CI, 45.7 – 59.1%) and cough
(47.6% with 95% CI, 41.2 – 54.0%) were the most common symptoms.
Expectoration was a notable symptom in 19.5% (95% CI, 11.7 – 30.7).
The spectrum of clinical manifestations included generalized (headache,
fatigue, rash and myalgia), respiratory (cough, dyspnea, rhinorrhea,
nasal congestion and sore throat) and gastrointestinal (nausea,
vomiting, abdominal pain and diarrhea) symptoms.
