We present a case of cytomegalovirus (CMV) reactivation after remission of COVID-19 in a kidney transplant patient, admitted to the emergency department. Fever, dyspnea, weakness and tachypnea are the most common symptoms of COVID-19, which can mislead physicians to make inappropriate decisions. We concluded that CMV can potentially increase the mortality risk of kidney transplant recipients (KTRs).
