A biphasic fever is more often seen in children compared to adults. The first fever arrives with the onset of general constitutional symptoms, and the second accompanying the onset of the neurological symptoms.Symptoms can vary depending on the virus responsible for infection. Enteroviral meningitis (the most common cause) typically presents with the classic headache, photophobia, fever, nausea, vomiting, and nuchal rigidity. With coxsackie and echo virus specifically, a maculopapular rash may be present, or even the typical vesicles seen with Herpangina. Lymphocytic choriomeningitis virus (LCMV) can be differentiated from the common presenting meningeal symptoms by the appearance of a prodromal influenza-like sickness about 10 days before other symptoms begin. Mumps meningitis can present similarly to isolated mumps, with possible parotid and testicular swelling. Interestingly, research has shown that HSV-2 meningitis most often occurs in people with no history of genital herpes, and that a severe frontal headache is among the most common presenting symptoms. Patients with varicella zoster meningitis may present with herpes zoster (Shingles) in conjunction with classic meningeal signs. Meningitis can be an indication that an individual with HIV is undergoing seroconversion, the time when the human body is forming antibodies in response to the virus. Causes
The most common causes of viral meningitis in the United States are non-polio enteroviruses. The viruses that cause meningitis are typically acquired from sick contacts.
