Answer

During the early phase of the disease (first 4-5 days), virus can be detected in serum, plasma, circulating blood cells, and tissues. Virus isolation, nucleic acid detection, and antigen detection are more useful to diagnose infection. At the end of the acute phase of illness, serology becomes the method of choice.
