“We showed that even though COVID-19 is caused by a new virus, in an otherwise healthy person, a robust immune response across different cell types was associated with clinical recovery, similar to what we see in influenza,” says study co-author Prof. Katherine Kedzierska.

The female sought specialized care 4 days after the onset of viral infection symptoms. These symptoms included lethargy, a sore throat, a dry cough, pleuritic chest pain, some shortness of breath, and a fever.

They were able to leave the hospital and enter self-isolation 11 days after symptom onset, and they were symptom-free by day 13.
