Rift Valley fever virus (RVFV) is a newly discovered arboviral pathogen that infects humans and livestock. Numerous outbreaks have occurred in Africa and the Arab Peninsula. Epizootics of RVFV are sporadic and frequently associated with ongoing floods and excessive rainfall. This leads to the development of infected Aedes mosquitoes, which then amplify transmission by other mosquito species (like Anopheles and Culex genera). In animals, it typically results in high rates of death and abortion. In humans, Rift Valley fever (RVF) manifests as clinical symptoms that may vary in intensity from minor to severe. Common symptoms include retinitis, hepatitis, delayed onset encephalitis, and hemorrhagic illness. The possibilities for containing RVFV outbreaks are limited due to the lack of authorized human vaccinations and treatments. Although molecular detection techniques are available, they can only recognize viral nucleic acids during the short viremic phase. There are currently no specific treatments for RVFV infection. Ribavirin is one of the few therapies for viral hemorrhagic fevers, but severe adverse effects restrict its use. Significant studies have been done in recent years on using Nanotechnology to diagnose and treat viruses. This review summarizes the common and recent diagnostic and therapeutic approaches for RVFV, including nanoparticles, intravenous immunoglobulin (IVIG), stem cells, vaccines, and antibody-based therapies.
裂谷热病毒(RVFV)是一种新发现的虫媒病毒病原体,可感染人类和牲畜。非洲和阿拉伯半岛已发生多次疫情。RVFV的动物流行病呈散发性,且常常与持续的洪水和过多降雨有关。这会导致受感染的伊蚊滋生,进而通过其他蚊种(如按蚊属和库蚊属)扩大传播。在动物中,它通常会导致高死亡率和流产。在人类中,裂谷热(RVF)表现出的临床症状严重程度不一,从轻症到重症都有。常见症状包括视网膜炎、肝炎、迟发性脑炎和出血性疾病。由于缺乏经批准的人类疫苗和治疗方法,控制RVFV疫情的可能性有限。虽然有分子检测技术,但它们只能在病毒血症的短时期内识别病毒核酸。目前尚无针对RVFV感染的特效治疗方法。利巴韦林是治疗病毒性出血热的少数疗法之一,但严重的不良反应限制了其使用。近年来,在利用纳米技术诊断和治疗病毒方面开展了大量研究。本综述总结了RVFV常见的和最新的诊断及治疗方法,包括纳米颗粒、静脉注射免疫球蛋白(IVIG)、干细胞、疫苗和基于抗体的疗法。
