MARKET TALK: Per RTRS: "South Korean health authorities raised new concerns

about the novel coronavirus after reporting last month that dozens of patients

who had recovered from the illness later tested positive again. The findings

suggested that some people who survived COVID-19 could become reinfected with

the virus that causes it, potentially complicating efforts to lift quarantine

restrictions and to produce a vaccine. But after weeks of research, they now say

that such test results appear to be "false positives" caused by lingering - but

likely not infectious - bits of the virus."
