I honestly don't get why people are so stressed over this flu. At the minute the death toll is way less than normal flu. XD
It's actually relatively harmless compared to how many people die a month from influenza. Even doctors have said that.
Yes, it may come back stronger, but that's why scientists are working diligently. If people are diligent then this flu isn't even that serious. Sheesh.
But I agree with avex, cancel the Osaka tours for now.
