Expert: Viral shedding still possible 10 days after first COVID symptoms

An executive board member of the Japan Medical Association says some people with COVID-19 could infect others 10 days after developing symptoms.

Kamayachi Satoshi told a news conference on Wednesday that 10 to 20 percent of infected people could still be shedding the virus seven to ten days after the onset of symptoms.

Prime Minister Kishida Fumio said on Tuesday that the government had decided to shorten the self-isolation period for patients with symptoms from 10 days to seven. The period for asymptomatic people has been cut from seven days to five as long as they test negative.
