Agreed. And not just Hinata's family; Yurina's brother is affected yet they also decided to keep her in the dark. But perhaps that's the point? Given the stronger trans vibes in the last few chapters, maybe the point is that things will get solved once they are honest with their loved ones.

I don't think it's the virus, or at least just the virus. The president, for example, was ecstatic when she transformed and was quick to adapt to male life. And from what we've seen, I believe the virus works like "the more they accept their new gender, the more they transform" rather than "the more they transform, the more they accept their new gender".
