rabies virus
English Explanation
The rabies virus is a deadly virus that causes rabies, a serious viral disease characterized primarily by inflammation of the brain (encephalitis) and the nervous system. The virus belongs to the Lyssavirus genus and is typically transmitted through the saliva of infected animals, most commonly through bites.
Once the virus enters the human body, it travels along the peripheral nervous system to the central nervous system, eventually reaching the brain. The incubation period for rabies can vary, ranging from weeks to months, depending on various factors such as the location of the bite, the amount of virus introduced, and the individual's immune response.
Symptoms of rabies may include fever, headache, and intense neurological symptoms like anxiety, confusion, agitation, and hallucinations. As the disease progresses, it can lead to paralysis, coma, and ultimately death if not treated promptly.
Preventive measures include vaccination for pets and high-risk individuals, and post-exposure prophylaxis (PEP) should be administered immediately after potential exposure to the virus.
Chinese Explanation
狂犬病毒是一种致命病毒,导致狂犬病,这是一种主要以脑部炎症(脑炎)和神经系统受影响为特征的严重病毒性疾病。该病毒属于狂犬病毒属,通常通过感染动物的唾液传播,最常见的是通过咬伤。
一旦病毒进入人体,它会沿着外周神经系统向中枢神经系统移动,最终到达大脑。狂犬病的潜伏期可以有所不同,从几周到几个月不等,具体取决于咬伤的部位、引入的病毒量以及个体的免疫反应等多个因素。
狂犬病的症状可能包括发烧、头痛,以及强烈的神经系统症状,如焦虑、困惑、烦躁和幻觉。随着疾病的发展,它可能导致瘫痪、昏迷,最终如不及时治疗将导致死亡。
预防措施包括为宠物和高风险个体接种疫苗,潜在暴露于该病毒后需立即进行暴露后预防(PEP)治疗。
