传染病传播是病原体从已感染者排出,经过一定的传播途径,传入易感者而形成新的传染的全部过程。传染病得以在某一人群中发生和传播,必须具备传染源、传播途径和易感人群三个基本环节。这三个环节的相互连接和作用往往受到自然环境因素、社会环境因素、管理等因素的影响和制约,甚至决定着传染病发生、发展与转归。随着全球环境逐渐恶化,环境对传染病的传播的影响越来越大,对其分析与研究具有较大的研究意义和价值。
Infectious disease transmission is the pathogen discharged from the infected person, through a certain route of transmission, the introduction of susceptible and the formation of a new infection the entire process. Infectious diseases can occur and spread in a certain population. They must have three basic links: source of infection, route of transmission and susceptible population. The interconnection and function of these three links are often influenced and restricted by natural environment factors, social environment factors and management factors, and even determine the occurrence, development and return of infectious diseases. With the gradual deterioration of the global environment, the impact of the environment on the spread of infectious diseases is becoming greater and greater, which is of great research significance and value for its analysis and research.
