什麼是Murray Valley Encephalitis Virus
Murray Valley Encephalitis Virus (MVE) fever is a generally mild, limited viral infection. In a small number of cases, the infection may cause encephalitis (swelling and inflammation of the brain).
您如何獲得Murray Valley Encephalitis Virus？
Murray Valley Encephalitis Virus is transmitted only by infected mosquitoes. The virus is not transmitted person to person.
易感性和抵抗力
All persons are susceptible. Recovery is generally universal and followed by long-lasting immunity. Adults living in areas where MVE is common are generally immune due to unapparent infections acquired in childhood. Second attacks do not occur.
有哪些症狀？
The majority of the infections do not cause any symptoms. Some infections (about 1 in 800 cases) may produce mild fever, headache, nausea and vomiting. In a small number of cases, the infection may cause inflammation of the brain (encephalitis) with high fever, severe headache, lethargy, drowsiness, altered mental state, tremors and sometimes convulsions. Up to 25 percent of the severe cases may die. Survivors may have permanent neurological impairment.
預防措施
避免被蚊子叮咬是預防這種感染的最佳方法。為了減少暴露在蚊蟲叮咬中的風險，請使用驅蟲劑，在無法在屏蔽或裝有空調的設施中睡覺的情況下，使用氯菊酯浸漬的蚊帳，並穿上防護服。
治療
There is no specific treatment for this self-limited disease other than therapy of symptoms and supportive treatment for severe cases of encephalitis.
通常在哪裡發生？
該病毒僅在澳大利亞北部和巴布亞新幾內亞發現。
