近日，印度南部喀拉拉邦再次报告尼帕病毒（Nipah virus）感染病例，引发全球关注。尼帕病毒是一种人畜共患病毒，主要通过果蝠传播，也可在人际间传播，致死率高达40%至75%。感染者可能出现发热、头痛、呼吸困难，严重时可导致脑炎甚至死亡。目前尚无特效药或疫苗，治疗以支持性护理为主。值得警惕的是，该病毒具有高度传染性和致命性，但传播途径相对有限，主要通过密切接触感染者体液或受污染食物传播。世界卫生组织（WHO）已将其列为优先研究的病原体之一。对中国而言，目前尚未发现本土病例，且我国拥有较为完善的传染病监测与应急响应体系。只要避免前往疫情高发区、注意个人卫生、不接触可疑动物或患者，公众感染风险极低。专家建议保持关注但无需恐慌，科学防护是关键。
Recently, new cases of Nipah virus infection have been reported in Kerala, southern India, drawing global attention. Nipah virus is a zoonotic pathogen primarily transmitted by fruit bats and can also spread between humans, with a fatality rate ranging from 40% to 75%. Symptoms include fever, headache, respiratory distress, and in severe cases, encephalitis or death. There is currently no specific antiviral treatment or vaccine; care remains supportive.Although highly lethal and capable of human-to-human transmission, the virus spreads mainly through close contact with infected bodily fluids or contaminated food, limiting its transmission routes. The World Health Organization (WHO) has listed Nipah virus as a priority pathogen for research and development.For China, no local cases have been reported to date. The country maintains a robust infectious disease surveillance and emergency response system. As long as people avoid traveling to outbreak areas, practice good hygiene, and refrain from contact with potentially infected animals or individuals, the risk to the general public remains extremely low. Experts advise staying informed but not panicking—scientific prevention is key.
