Dear Editor,

We would like to share ideas on the article “COVID-19 reinfection in a kidney transplant recipient, time for rethinking?”.1 Quiroga et al. concluded that “reinfections in kidney transplants are plausible and require paying attention to those patients who developed COVID-19 symptoms even if they have had a previousepisode”.1 A reinfection of COVID-19 is possible in either normal or immunocompromised host. The continuous mutation occurs and it can cause the problem. At present, a bigger concern is on the post vaccination COVID-19. The vaccine is presently suggested to everyone and if an already infected transplant recipient gets COVID-19 vaccine, he/she can still at risk to get reinfection.

For the present case, the described situation is matched and it can be a good case study. However, another possibility that should be mentioned is the possibility of long chronic asymptomatic carrier of virus after the first infection. Long COVID-19 becomes a new condition that requires further studies. It is already reported for a persistence of disease for many months.2 Before discharge of a case, the confirmation for negative PCR is usually requires, although it might not be performed in some resource limited area (such as in Indochina). However, there is usually no follow-up PCR test for reconfirming for no false negative PCR of the first time PCR result before discharge.
