A positive cytomegalovirus is a cytomegalovirus infection that can be treated primarily by taking antiviral medications, such as cytarabine and ganciclovir. The disease may be caused when directly infected with cytomegalovirus, resulting in a positive cytomegalovirus test result. Patients may have symptoms such as yellowish skin color all over the body as well as enlarged liver and spleen. At this time, antiviral drugs such as cytarabine, ganciclovir or acyclovir should be selected for treatment under the guidance of a specialized physician, which can play a better inhibitory role and help to alleviate the symptoms. Attention should be paid to clarify whether there are adverse reactions during the use of medication, and it is usually not necessary to stop the use of medication if the adverse reactions are mild.
