Dear Editor,We would like to share ideas on the publication “Re‐infection with SARS‐CoV‐2 in solid‐organ transplant (SOT) recipients: Incidence density and convalescent immunity prior to re‐infection.
” Even after establishing cellular and humoral immune responses, Morris et al. found that SOT patients infected with SARS‐CoV‐2 are at high risk for re‐infection.
We agree that in the case of SOT, the immunological response to COVID‐19 may differ from that of healthy people. The current research can show that re‐infection is a possibility. The asymptomatic COVID‐19 is an essential issue to keep in mind.
It's possible that COVID‐19 is asymptomatic in the SOT case. The asymptomatic COVID‐19 cannot be ruled out in this investigation. In addition, the actual number of re‐infections is unknown. It's possible that some people will have more than one incident of reinfection. As a result, repeated multiple asymptomatic COVID‐19 reinfections could alter the incidence density calculation.
