正在发生什么

Nigeria is dealing with another 2026 Lassa fever outbreak, and WHO material available here says Lassa fever is endemic in Nigeria with recurrent seasonal outbreaks. No current October 2026 WHO Disease Outbreak News item or directly retrieved Nigeria Centre for Disease Control and Prevention situation report is available here. Media reports on 13 October quoting NCDC’s week 40 report said there were 1,138 confirmed cases, 268 deaths, and 8,414 suspected cases in 2026, with confirmed cases across 24 states and 119 local government areas; those figures are unverified here. The same reports said week 40 recorded 3 new confirmed cases and 1 death, down from 13 new confirmed cases in week 39. Reported response measures include rapid response deployments in high-burden states, active case search, contact tracing, infection prevention and control work, PPE supply, training for frontline workers, and public advice on sanitation, food storage, and early care seeking.

谁会受影响以及如何传播

拉沙热是一种主要在西非包括尼日利亚发现的病毒性疾病。人们通常通过被Mastomys鼠类尿液或粪便污染的食物、灰尘或家庭用品感染。人传人传播可通过直接接触血液或其他体液发生，但WHO表示这种传播不常见，主要在缺乏良好感染预防的医疗环境中引起关注。大多数感染轻微或无症状，但部分病例会严重，WHO表示目前没有获批疫苗。
