Resumen
large number of coronavirus disease 2019 (COVID-19) patients have been cured
and discharged due to timely and effective treatments. While some discharged
patients have been found re-positive nucleic acid again in the recovery phase. Until
now, there is still a great challenge to its infectivity and the specific potential
mechanism which need further discussion. However, more intensive attention should
be paid to the prognosis of the recovered patients. In this review, we mainly focus on
the characteristics, potential reasons, infectivity, and outcomes of re-detectable
positive patients, thereby providing some novel insights into the cognition of
COVID-19.
