Introduction

SAY you have caught COVID-19 and recovered – are you now immune for life, or could you catch it again? We just don't know yet.

In February, reports emerged of a woman in Japan who had been given the all-clear after having COVID-19 but then tested positive for the SARS-CoV-2 virus a second time. There have also been reports of a man in Japan testing positive after being given the all-clear, and anecdotal cases of second positives have emerged from China, too.
