有效感染机会群体(EIOP)假说在SIR感染理论中的应用

Effective Infection Opportunity Population (EIOP) Hypothesis in Applying SIR Infection Theory

Hiroshi Isshiki, Masao Namiki, Takeshi Kinoshita, Ryosuke Yano

摘要:

1927年由Kermack-McKendrick提出的SIR传染理论讨论了具有均匀分布的孤立种群的传染问题。在感染中,存在两个方面:(1)数量方面和(2)时间方面。由于SIR理论是一种平均场论,它不能同时兼顾这两个方面。如果数量方面匹配,时间方面不能匹配,反之亦然。感染从一个集群开始,然后扩散到不同的地方,增加了感染的规模。一般来说,即使在大城市的感染情况下,感染也会在有限的人群中增长。并木发现并命名这种种群为有效种群。他提出,如果假设被采纳,数量和时间方面可以同时匹配。

英文摘要:

The SIR infection theory initiated by Kermack-Mckendrick in 1927 discusses the infection in an isolated population with uniform properties such as the uniform population distribution. In the infection, there exist two aspects: (1) The quantitative aspect and (2) the temporal aspect. Since the SIR theory is a mean-field theory, it can't match both aspects simultaneously. If the quantitative aspect is matched, the temporal aspect can't be matched, versa. The infection starts from a cluster, and it spreads to different places increasing the size of the infection. In general, even in the case of the infection in a big city, the infection grows within a limited population. Namiki found and named this kind of population as an effective population. He proposes that if the hypothesis is adopted, the quantitative and temporal aspects can be matched simultaneously.
