The ongoing outbreak of Zika virus (ZIKV) in Brazil followed introduction of the virus after international mass gatherings including the FIFA Soccer World Cup and an international canoe race, in 2014 [1]. However, phylogenetic analysis demonstrates that ZIKV circulated in Brazil from 2013 resulting from a single introduction [2]. The Rio Olympics have been held and the world is waiting to see what impact this may have on the global spread of Zika. Risk assessments had given inconsistent predictions [3], [4]. In April 2018, the 21st Commonwealth Games will be held on the Gold Coast in Queensland, Australia (Gold Coast 2018 or GC2018) [5]. Among the potential health risks associated with the games is ZIKV. We discuss the likelihood of local ZIKV transmission in connection with GC2018 [6].
