摘要
病毒性出血热是严重的病毒感染，有进展为多器官功能障碍和严重内皮损伤的不同趋势，可导致休克和出血。不是所有病例都分布在热带，尽管在夏天或雨季传染媒介最活跃的时候发病率可能升高。
Viral haemorrhagic fevers are severe viral infections with a variable tendency to progress to multi-organ dysfunction and severe endothelial injury, leading to shock and haemorrhage. Not all are tropical in distribution, though their incidence may increase in summer or rainy seasons, when vectors are most active.
