事件概述

世界卫生组织（WHO）本周三明确表示，近日在一艘游轮上暴发的汉坦病毒疫情不会演变为类似新冠疫情的全球大流行。世卫组织强调，汉坦病毒的传播途径与新冠病毒截然不同，不具备人际持续传播的能力。

汉坦病毒特性

汉坦病毒主要通过接触受感染啮齿动物的尿液、粪便或唾液传播，人类吸入被污染的气溶胶后可能感染。与呼吸道病毒不同，汉坦病毒在人与人之间的传播极为罕见。这意味着该病毒无法像新冠那样通过社区传播形成大规模流行。

世卫发言人指出：“我们目前所处的情况与新冠疫情初期完全不同。汉坦病毒的传播链可以通过隔离感染者和控制啮齿动物来有效阻断。”

游轮疫情情况

据悉，该游轮上已确认多例汉坦病毒感染病例。船上乘客和船员正接受医学观察，部分出现症状的旅客已被转移至医疗机构。汉坦病毒感染可导致汉坦病毒肺综合征（HPS），症状包括发热、肌肉酸痛和呼吸困难，重症病例可能危及生命。

卫生部门正在对游轮进行彻底消毒，并追踪所有密切接触者的健康状况。

公众防护建议

专家建议公众避免接触野生啮齿动物，保持居住环境清洁，妥善存放食物以减少鼠类 attracted。如果出现发热、呼吸急促等症状且有啮齿动物接触史，应及时就医并告知医生相关暴露情况。

Overview

The World Health Organization (WHO) stated clearly on Wednesday that the recent hantavirus outbreak on a cruise ship will not escalate into a global pandemic similar to COVID-19. The WHO emphasized that hantavirus spreads through entirely different mechanisms and does not sustain human-to-human transmission.

Understanding Hantavirus

Hantavirus is primarily transmitted through contact with infected rodents’ urine, droppings, or saliva. Humans become infected by inhaling contaminated aerosols. Unlike respiratory viruses, hantavirus rarely spreads between people, making sustained community transmission virtually impossible.

A WHO spokesperson noted: “The situation we face is fundamentally different from the early days of COVID-19. Hantavirus transmission chains can be effectively interrupted by isolating infected individuals and controlling rodent populations.”

The Cruise Ship Outbreak

Multiple hantavirus cases have been confirmed aboard the cruise vessel. Passengers and crew are under medical observation, with symptomatic individuals transferred to healthcare facilities. Hantavirus infection can cause Hantavirus Pulmonary Syndrome (HPS), with symptoms including fever, muscle aches, and breathing difficulties. Severe cases can be life-threatening.

Health authorities are conducting thorough disinfection of the vessel and tracking all close contacts.

Public Health Guidance

Experts advise the public to avoid contact with wild rodents, maintain clean living environments, and store food properly. Anyone experiencing fever or breathing difficulties with a history of rodent exposure should seek medical attention promptly.
