Nipah virus outbreaks in hospitals in India primarily result from the virus’s high transmissibility combined with inadequate infection control measures. Initially transmitted to humans from fruit bats, Nipah virus can then spread from person to person—especially among close contacts such as family members or healthcare workers. In outbreaks in Kerala and other Indian states, the index patient is often admitted to a general ward with symptoms like fever, headache, and altered mental status, without immediate recognition as a potential high-risk infectious case. This delays isolation and allows the virus to spread rapidly in settings lacking proper personal protective equipment (PPE) and infection prevention protocols. Furthermore, frequent movement of staff and patients, shared medical equipment, and limited awareness of the virus amplify the risk of nosocomial transmission. The World Health Organization identifies healthcare-associated transmission as a critical driver of Nipah outbreak escalation. Therefore, strengthening early detection, rapid diagnostics, strict isolation procedures, and healthcare worker training is essential to prevent hospitals from becoming amplifiers of the epidemic.
印度尼帕病毒（Nipah virus）疫情在医院暴发，主要源于其高度传染性与医疗防护不足的双重因素。尼帕病毒最初通过果蝠传播给人类，随后可在人与人之间传播，尤其是在密切接触者中，如家庭成员或医护人员。在印度喀拉拉邦等地的疫情中，首例患者常因发热、头痛、意识障碍等症状被送入普通病房，而未及时识别为高危传染病，导致病毒在缺乏隔离措施和防护装备的环境中迅速扩散。此外，医院内频繁的人员流动、共用医疗设备以及对病毒认知不足，进一步加剧了院内传播风险。世界卫生组织指出，尼帕病毒在医疗机构中的传播是疫情扩大化的关键环节。因此，加强早期识别、快速诊断、严格隔离及医护人员培训，是防止医院成为疫情‘放大器’的核心措施。
