Aiding in the diagnosis of central nervous system infection caused by dengue virus
Detection of dengue virus nucleic acid in cerebrospinal fluid (CSF) is suggestive of recent exposure or acute central nervous system infection with dengue virus.
The presence of dengue virus nucleic acid in CSF or serum can be used as a marker for acute-phase infection.
Patients with a history of symptoms for more than 1 week may be negative by molecular tests (ie, real-time PCR) and may require serologic testing to confirm the diagnosis of dengue virus infection.
