General Virology and DNA Viruses
The most sensitive test for the diagnosis of herpes simplex (HSV) meningitis in a new born infant is which of the following?
|A||Cerebrospinal fluid (CSF) protein analysis|
|C||HSV IgG antibody|
|D||HSV polymerase chain reaction|
a. HSV meningitis or encephalitis is difficult to diagnose by laboratory tests, as there is a low titer of virus present in the cerebrospinal fluid.
b. Neonatal HSV infects the child during the birth process. While culture, Tzanck smear, and even antibody tests may be useful in adults, particularly those with HSV-rich lesions, they are not useful for CSF testing.
c. Only PCR is sensitive enough to detect HSV DNA in the CSF Once diagnosed rapidly, HSV encephalitis or meningitis can be treated with acyclovir.
