Doctors have shared new details about the first case of Wuhan coronavirus in the United States.

The first patient was a 35-year-old resident of Snohomish County, Washington, with no history of major health problems, said the scientific paper published Friday in the New England Journal of Medicine.

Return from Wuhan: The patient visited family in Wuhan, and flew back on January 15. He had not visited the seafood market linked to the outbreak, or have any known contacts with sick people during his visit.

Symptoms: The man started with mild, nonspecific symptoms, and sought medical attention on January 19 after coughing for four days. The very next day, doctors confirmed he had the novel coronavirus.

Throughout his illness, he experienced a range of symptoms including fever, cough, fatigue, nausea, vomiting, diarrhea and runny nose. On day nine of his illness, his chest X-ray showed signs of pneumonia.

Road to recovery: As of January 30, he no longer had a fever, and his symptoms were gone except for his cough, which was “decreasing in severity,” the doctors wrote. Officials are monitoring close contacts in the US but have not found evidence he transmitted the virus to anyone else.
