It is important to make sure that when samples are collected for testing on suspected patients, procedures are followed properly,” it said. Based on current studies, there is a period of about two weeks between the onset of symptoms and clinical recovery of patients with mild COVID-19 disease, the agency said. “We are aware that some patients are PCR positive after they clinically recover, but we need systematic collection of samples from recovered patients to better understand how long they shed live virus,” it said.
