其他表现
最终死于埃博拉病毒病的患者往往在感染早期即出现临床征象,并且通常在感染后的 6-16 日内死亡(由于休克和多器官功能衰竭)。[4]Leroy EM, Gonzalez JP, Baize S. Ebola and Marburg haemorrhagic fever viruses: major scientific advances, but a relatively minor public health threat for Africa. Clin Microbiol Infect. 2011 Jul;17(7):964-76.

在既往暴发期间,30%-36% 的感染患者有出血表现(如鼻衄、牙龈出血、咯血、易发瘀斑、结膜出血、血尿、注射或静脉穿刺部位渗血); 但在 2014 年暴发中,仅 5%-18% 的患者报告有出血表现。[8]Barrette RW, Metwally SA, Rowland JM, et al. Discovery of swine as a host for the Reston ebolavirus. Science. 2009 Jul 10;325(5937):204-6.

如果无外部体征,内出血可能会被漏诊。
提示重度感染或晚期感染的其他体征包括呃逆、低血压、心动过速、肝肿大、脾肿大、意识模糊和癫痫发作。
多达一半的患者会出现斑丘疹,在有凝血障碍的患者中,它有可能进展为紫癜样斑丘疹或瘀斑样斑丘疹。[16]Kortepeter MG, Bausch DG, Bray M. Basic clinical and laboratory features of filoviral hemorrhagic fever. J Infect Dis. 2011 Nov;204 Suppl 3:S810-6.
