First, it appears the Washington coronavirus patient has largely recovered, according to a writeup today in the New England Journal of Medicine, which described his #nCoV2019 symptoms as largely resolved, although he's still in isolation.https://www.nejm.org/doi/full/10.1056/NEJMoa2001191 …
"The patient stated that he had seen a health alert from the U.S. Centers for Disease Control and Prevention (CDC) about the novel coronavirus outbreak in China and, because of his symptoms and recent travel, decided to see a health care provider," the report reads. "Given the patient's travel history, the local and state health departments were immediately notified."
After testing positive for the deadly coronavirus, the patient was admitted to an isolation unit at Providence Regional Medical Center. On his sixth day of hospitalization, according to the NEJM, "clinicians pursued compassionate use of an investigational antiviral therapy."
After treatment with the antiviral, Remdesivir, "the patient's clinical condition improved." The patient is still in the hospital, but all of his symptoms except a cough have resolved.
