摘要

Zika 病毒 (ZIKV) exhibits unique 傳播 dynamics in that it is concurrently spread by a mosquito vector and through sexual contact. Due to the highly asymmetric durations of infectiousness between males and females-it is estimated that males are infectious for periods up to 10 times longer than females-we show that this sexual component of ZIKV 傳播 behaves akin to an asymmetric 滲流 process on the 網絡 of sexual contacts. We exactly solve the properties of this asymmetric 滲流 on random sexual contact 網絡s and show that this process exhibits two 流行病學c transitions corresponding to a core-periphery structure. This structure is not present in the underlying contact 網絡s, which are not distinguishable from random 網絡s, and emerges because of the asymmetric 滲流. We provide an exact analytical description of thi
