Which cell type predominates in CSF during classic viral meningitis?

Explanation:
In classic viral meningitis, the CSF shows a lymphocyte-predominant pleocytosis. The antiviral immune response in the CNS is mainly driven by lymphocytes, so lymphocytes are the most numerous cells in the CSF. This pattern helps distinguish it from bacterial meningitis, where neutrophils predominate; monocytes/macrophages can be present but are not the main cells in the viral form.
