Answer

Transient acute hemolysis may occur secondary to certain infectious diseases, such as M pneumoniae infection and infectious mononucleosis (eg, EBV). Other viral infections, such as influenza, HIV, CMV, rubella, varicella, and mumps, have also been reported to be associated with a hemolytic anemia due to cold agglutinins. Associated illnesses also include subacute bacterial endocarditis, syphilis, and malaria. The development of a febrile illness in a patient with chronic cold agglutinin disease may also accelerate hemolysis.
