ABSTRACT
After recovery from COVID-19, a person may become infected again due to reactivation of the virus inside the human body or reinfection with a genetically distinct mutant virus owing to reinfection. The COVID-19 reinfection has been recorded all around the world, albeit it is still uncommon. The reinfection with COVID-19 raises several questions about virus characteristics such as mutation, growth, functioning, and transmissibility, level and durability of immunity, diagnosis, therapy, and efficacy of vaccine(s) on genetically modified viruses and their durability and safety. This chapter focuses on various aspects of COVID-19 reinfection, including its severity, frequency, immunopathogenesis, immune responses, effect on vaccine development, Corona waves and herd immunity, management and prevention strategies. COVID-19 reinfections are often asymptomatic or mildly symptomatic, and are milder than first infections, with a few exceptions. The management of reinfection should be the same as the treatment of the first COVID-19 infection. The deep, extensive, rapid and real-time whole-genome sequencing studies, as well as an enhanced vaccination drive, and rigorous adherence to COVID-19 appropriate behavior, would be critical in limiting the severity of transmission and reinfection. © 2022 Elsevier Inc.
