Chen Qingbo, 42, was among the first batch of patients who recovered from novel coronavirus pneumonia and was discharged from Jinyintan Hospital in Wuhan, the epicenter of the coronavirus outbreak, a month ago.

Now, a month after he left the hospital, Chen's life is back to normal. Last week, Chen heard from his doctor that medical experts have called upon cured coronarivus patients to donate plasma at hospitals as neutralizing antibodies have been identified in the plasma of some patients.
