“Some of those 5 kids were in school, but since they showed no symptoms, the officials apparently think those at the school(s) are not in any danger.”
The truth is that since the fluids themselves are contagious then anyone who has the fluids on their skin or clothing are also contagious if the right conditions are met. That cannot be denied. Those fluids could also be transferred to items such as door handles. So a child on there way to school after being in the area with uncle Eric could definitely expose others at school. No matter how remote the chance. It could happen.
This is probably going to get a lot worse before it gets better...
