病媒传播疾病的随机家庭模型

A stochastic household model for vector-borne diseases

Andrew Black, Andrew Smith, Alun Lloyd, Joshua Ross

摘要:

我们引入了一个随机的家庭模型的媒介传播的疾病,特别是有关的突出载体属于伊蚊属,因此寨卡病毒,基孔肯雅病毒和登革热病毒。在这个模型中,载体保持在每个家庭的本地,而宿主在其家庭中的一部分时间和人口中的其余部分时间随机混合。这是近似的两种类型的分支过程,使我们能够有效地计算一些有用的流行病学特征,如生殖数量,早期增长率和家庭类型的比例,后代分布,大爆发的概率,和家庭内的最终规模分布。我们比较了喷洒的控制干预措施-减少每个家庭中的病媒数量-和社会距离-让个人在家里花更多的时间-在这些特征方面。

英文摘要:

We introduce a stochastic household model for vector-borne diseases, in particular as relevant to prominent vectors belonging to the Aedes genus and hence the Zika, chikungunya, and dengue viruses. In this model, vectors remain local to each household, while hosts mix for a proportion of their time in their household and the remaining proportion in the population at random. This is approximated with a two-type branching process, allowing us to efficiently calculate a number of useful epidemiological characteristics, such as reproductive numbers, early growth rates and household-type proportions, offspring distributions, probabilities of a major outbreak, and within-household final size distributions. We compare control interventions of spraying -- reducing the number of vectors in each household -- and social-distancing -- having individuals spend more time at home -- in terms of these characteristics.
