近期，尼帕病毒（Nipah virus）在部分地区引发关注，但公众无需过度恐慌。尼帕病毒并非新出现的病毒，它最早于1998年在马来西亚被发现，因在森美兰州双溪尼帕（Sungai Nipah）爆发而得名。该病毒主要通过果蝠（狐蝠）传播，也可通过受感染的动物（如猪）或人与人之间的密切接触传播。尼帕病毒感染的症状包括发热、头痛、嗜睡、意识模糊，严重时可导致脑炎甚至死亡。病死率较高，约为40%至75%，但病例总体数量较少，且多集中在南亚和东南亚地区。世界卫生组织（WHO）已将尼帕病毒列为优先研究的病原体之一，相关疫苗和治疗手段正在研发中。目前尚无特效药或获批疫苗，预防的关键在于避免接触可能携带病毒的动物、保持良好的个人卫生习惯，以及在疫情发生地区加强监测与隔离措施。专家强调，虽然尼帕病毒具有高致病性，但其传播能力有限，只要采取科学防控措施，风险可控。因此，公众应理性看待，不必惊慌，更不应传播未经证实的信息。
Recently, the Nipah virus has drawn attention in certain regions, but there is no need for public panic. The Nipah virus is not a newly emerged pathogen—it was first identified in 1998 during an outbreak among pig farmers in Sungai Nipah, Malaysia, from which it gets its name. The virus is primarily carried by fruit bats (flying foxes) and can spread to humans via infected animals like pigs or through close human-to-human contact.Symptoms of Nipah virus infection include fever, headache, drowsiness, and confusion; severe cases can lead to encephalitis and even death. The case fatality rate is high—ranging from 40% to 75%—but overall case numbers remain low and are mostly confined to South and Southeast Asia. The World Health Organization (WHO) has listed Nipah virus as a priority pathogen for research, with vaccines and therapeutics currently under development.There is no approved vaccine or specific antiviral treatment yet. Prevention relies on avoiding contact with potentially infected animals, practicing good hygiene, and implementing surveillance and isolation measures in affected areas. Experts stress that while Nipah virus is highly pathogenic, its transmissibility is limited. With appropriate scientific and public health interventions, the risk remains manageable. Therefore, the public should stay informed, remain calm, and avoid spreading unverified information.
