Vietnam's first two nCoV infection cases convalescing well

Doctors at Cho Ray Hospital check on the health of 66-year-old Li Ding and his 28-year-old son Li Zichao (pictured), 28, February 3, 2020. They are the first two confirmed cases of nCoV infection in Vietnam on January 23. They remain in quarantine, but both have tested negative for the virus as of Tuesday, February 4, 2020.

Li Zichao first tested negative for nCoV on January 27. He's currently in stable health and is being monitored.

Zichao has health checks six times a day. He was treated with fever medication, exercises, sunbathing and other activities.

Zichao was to be discharged Tuesday, but he wanted to stay on in the hospital to take care of his father, who's still being treated. The hospital has arranged a room for Zichao to care for his father.

In another quanrantined room, Li Ding's health is getting better. He has no fever and can walk by himself now. His previous test for nCoV turned out negative; if he's tests negative for nCoV two times in a row, he would be deemed to recover.

Entry into quarantine rooms requires passcodes not known to patients.
