South Koreans hit polling booths as preliminary voting began for the Presidential election yesterday, amid a wave of community spread of the coronavirus. Picture: Chung Sung-Jun/Getty ImagesKim Woo-joo, a professor of infectious diseases at the Korea University Guro Hospital, said patients could have “relapsed”, while other experts said false test results could be to blame.

“We have been looking for this kind of data to understand do the antibodies last for quite some time? If so, to what extent do they protect us from future infection, more broadly.”
