Viral Meningitis/viral encephalitis is a relatively common but rarely serious illness that can be caused by many viruses. It usually appears as a sudden onset of fever with headache and may include confusion, decreased level of consciousness and, in some cases, a stiff neck or a rash. The illness usually lasts less than 10 days and recovery is usually complete. Vomiting, diarrhea and respiratory symptoms may be associated with enteroviruses, which are responsible for most of the cases where the cause is identified.
Enterovirus infections are common in the summer. Cases are spread by person-to-person contact. Good hygiene can help reduce the spread of these infections.
In Manitoba, there is an average about 30 cases of enterovirus per year. In 2001, 48 cases were reported. This year, 13 cases have been identified and approximately 20 more are under investigation. In the past month, four cases have been identified as due to enterovirus infection.
At this time, there are no results that indicate the presence of a human case of West Nile virus. It is possible that we may see human cases of West Nile virus in Manitoba this summer, but the risk to any individual is very low.
Public information is available by calling Health Links at 788-8200 in Winnipeg or 1-888-315-9257. Information on West Nile virus is also available on the Manitoba Health Web site at www.gov.mb.ca/health/wnv. If you think you have symptoms of viral meningitis or encephalitis, contact your physician.
