疾控部门：不必恐慌，国内至今零感染

Core Viewpoint - The recent outbreak of Nipah virus in West Bengal, India has raised global concern, but China has not reported any confirmed cases, indicating a relatively low impact on the country. However, there remains a risk of imported cases from abroad [1][3]. Group 1: Current Situation and Response - The National Disease Control Bureau of China has confirmed that there are currently no confirmed cases of Nipah virus in the country, and the impact of the outbreak in India is assessed to be minimal due to geographical separation [2][3]. - China has established a comprehensive monitoring and prevention system for Nipah virus, which includes laboratory testing capabilities across all 31 provincial disease control centers and the availability of self-owned testing kits [1][3][4]. Group 2: Transmission and Risks - Nipah virus is primarily transmitted from animals to humans, with direct contact with infected animals or their bodily fluids being the main route of infection. Foodborne transmission and limited human-to-human transmission also occur, particularly in close contact settings [2][3]. - The virus has a high fatality rate, ranging from 40% to 75%, and there are currently no approved treatments or vaccines available globally [1][2]. Group 3: Preventive Measures - Public health authorities in cities like Chongqing, Guangzhou, and Shenzhen have issued guidelines for the public, emphasizing the importance of scientific prevention and personal protection to reduce infection risk [6][8]. - Recommendations include avoiding travel to high-risk areas, monitoring health after visiting affected regions, and practicing good hygiene, such as washing hands after contact with animals [6][7][8].
