脑炎通常导致需要住院治疗的严重疾病。本研究的目的是描述流行病学住院脑炎在意大利，考虑到地理分布，病因，季节性和演变的住院率在最近几年。平均住院率为5.88/10万。对于这些住院治疗中的大多数（n=13 119，55.6%），没有报告脑炎的具体原因。最常见的病因分类为“病毒”，占此类住院的40.1%（n=4205）（发生率1.05/100 000）。在这一类别中，疱疹病毒是主要的病原体（n=1579，0.39/100 000）。本报告强调了“未另行说明的病毒性脑炎”（ICD-9编码049.9）的显著增加，而所有其他原因的减少。在这一组年龄≥ 65岁的人中注意到季节性模式。应加强对不明原因脑炎的具体监测，以确定新出现的病原体的潜在作用，并制定预防干预措施。
Encephalitis generally results in a serious illness requiring hospitalization. The aim of this study was to describe the epidemiology of hospitalization for encephalitis in Italy, taking into account the geographical distribution, aetiology, seasonality and evolution of hospitalization rates over recent years. The mean hospitalization rate was 5.88/100 000. For most of these hospitalizations (n=13 119, 55.6%), no specific cause of encephalitis was reported. The most common aetiological category was 'viral', which accounted for 40.1% (n=4205) of such hospitalizations (rate 1.05/100 000). Within this category, herpes virus was the leading causative agent (n=1579, 0.39/100 000). This report highlights a significant increase of 'viral encephalitis not otherwise specified' (ICD-9 code 049.9) vs. a reduction of all other causes. A seasonal pattern was noted in people aged >= 65 years in this group. Specific surveillance of encephalitis without known origin should be reinforced in order to identify the potential role of emerging pathogens and to design preventive interventions.
