It is endemic in Northern Australia and cases occasionally occur in South Eastern Australia.

Hospital admissions, emergency department, psychiatric outpatients and mortality data were obtained. We attempted to follow\u2010up all 53 cases of <jats:styled-content style=\"fixed-case\">MVEV<\/jats:styled-content> clinical infection that occurred in Western Australia from 1978 to 2011 inclusive.

Seven of the nine with paralysis or paresis were under 5\u2009years and they fared worse than other patients, requiring lengthy hospitalisation (median duration 133\u2009days). Two died due to complications of quadriplegia following a total of 691\u2009days in hospital. Nine surviving patients, including two with non\u2010encephalitic illness, required care for depression and other psychiatric conditions following <jats:styled-content style=\"fixed-case\">MVEV<\/jats:styled-content> infection.
