IFNA1 and infection: ZIKV has been demonstrated in the eye in models of in utero or post-natal mouse development (Li et al. 2021; Zhao et al. 2017), infection in adult mice when the IFN-response is lacking (Garcia et al. 2020; Miner et al. 2016; Singh et al. 2019), and CZS can be studied in a number of animal models in the laboratory (Caine et al. 2018; Narasimhan et al. 2020).
