Viral Meningitis Cases Increase

(Santa Ana) – County health officials say viral meningitis cases in Orange County are up 36% this year as compared to 2002 and are urging increased handwashing and other hygienic precautions to prevent infection with the virus.

Year to date, 223 cases of viral meningitis have been reported in Orange County, compared to 164 during the same time period last year. Statewide, viral meningitis cases are increasing, with some counties reporting a doubling or tripling of cases compared to just a year ago. “Viral meningitis is a seasonal illness, with the last significant increase in Orange County occurring in 1998,” said County Epidemiologist Dr. Hildy Meyers. “Most cases of viral meningitis are reported in the summer and fall, and the increase in cases this year appears to be widespread.”

While viral meningitis is typically a milder illness than the bacterial form of meningitis, it can be difficult to differentiate between the two conditions. “Anyone exhibiting meningitis symptoms beyond fever and headache, including stiff neck; nausea and vomiting; and mental status changes like drowsiness or confusion, should seek medical attention immediately,” said County Health Officer Dr. Mark Horton.

Most viral meningitis in the summer and fall is caused by enteroviruses, which can also cause other illness such as diarrhea. To help prevent infection, good hygiene is important. Recommendations include:

• Washing your hands after using the bathroom or changing diapers and before preparing food.

• Avoiding the sharing of water bottles or drinking from another person’s beverage container.

• Covering your mouth when coughing or sneezing.

While meningitis can be caused by a number of viruses, including West Nile virus (WNV), there is no indication that WNV is related to this increase in cases.
