Reactive CMV Colitis in Multimorbidity Patient with Ganciclovir Resistance- Post-COVID-19: A Case Report.

COVID-19 disease mainly causes mild upper respiretory diseases in infected people, with possible development of complications in 20% of the cases. The virus's predominance for bronchial epithelial tissue and reactive immune response to the virus can result in an overall immune reaction that can trigger latent infections such as cytomegalovirus (CMV) infection or cause bacterial, fungal, or viral coinfections. CMV infection can predispose to other viral respiratory infections, and chronic CMV infection state has been associated with impaired humoral immune response. An abundance of CMV IgG antibodies rate has even been correlated with a higher mortality rate. This state can occur due to underlying immunocompromised status (e.g., undergone transplantation or autoimmune disease) or comorbidity-relations susceptible to the development of complications (such as greater age and underlying chronic diseases), even in a post-COVID-19 state.
