Abstract:

The global situation of the coronavirus disease 2019 (COVID-19) infection remains concerning. As the viruses continue to evolve, the risk of reinfection has markedly increased. COVID-19 vaccination history, previous infection history, antibody titers, age and immune escape can all affect the occurrence of reinfection. Scientific rehabilitation training can help to alleviate post-acute COVID-19 sequalae, and vaccination remains a crucial measure of infection prevention. In the paper, we discussed the current epidemic situation of COVID-19, epidemiology of reinfection and its’ related factors, and strategies to provide reference for epidemic prevention and control.
