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.
