Commonly reported symptoms include shortness of breath, cough, fatigue, body aches, dizziness, fever, nausea, vomiting, and diarrhea. Additional symptoms may include chest pain, abdominal pain, chills, or weight loss. Symptoms can initially mimic common pulmonary diagnoses like pneumonia, but individuals typically do not respond to antibiotic therapy. In some patients, gastrointestinal symptoms can precede respiratory symptoms. Individuals typically present for care within a few days to weeks of symptom onset. At the time of hospital presentation, the individual is often hypoxic and meets systemic inflammatory response syndrome (SIRS) criteria, including fever. Physical exam can reveal rapid heart rate or rapid breathing. Auscultation of the lungs tends to be unremarkable, even in patients with severe lung disease. In some cases, the affected individuals have progressive respiratory failure, leading to intubation. Several affected individuals have needed to be placed in the intensive care unit (ICU) and on mechanical ventilation. Time to recovery for hospital discharge has ranged from days to weeks.
