疾病信息传播对疾病传播的影响

Research on Public Opinion Management under Public Health Emergencies

疾病传播过程中,易感人群可提前获得疾病信息并采取防护措施,从而抑制疾病传播。运用平均场方程和系统动力学方法来建模信息传播和疾病传播复杂系统,结果表明,政府及时发布疾病信息和个体主动自我防护,在疫情传播期间会有效抑制病毒的传播。在新媒体环境下,疾病信息的传播速度要比疾病本身传播更快,这种“速度优势”对于抑制疾病传播的意义重大,可以帮助人们更好理解疾病信息传播对疾病传播的影响,可以为疾病防控和舆情管理提供指导。

During the disease spread,susceptible people can obtain disease information in advance and take protective measures to suppress the disease spread.Mean field equations and system dynamics methods were applied to model the complex system of information dissemination and disease spread.The results show that the timely release of disease information and individual self-protection by the government will effectively suppress the spread of the virus during the epidemic transmission.Moreover,in the new media environment,disease information spreads faster than the disease itself.This“speed advantage”is important for suppressing the spread of disease.Our work can help better understand the impact of disease information dissemination on disease transmission,and can guide disease prevention and control and public opinion management.
