7 days after my daughter, I also developed a stomach bug. 3 days later, it's my spouse's turn. My daughter was taking probiotics. Could it be all caused by the same virus? Does my daughter risk getting it again?

Yes, it is possible for the same virus to spread to different family members. It is important to monitor symptoms and continue taking probiotics to help reduce symptoms if the virus returns. Stay hydrated and seek medical advice if needed.
