yeh thats true they should have let use no but there is nothing to do t avoid it!! bugs can be passed on before the child carrying is even sick from it and some children are carriers and dont even get sick from it, im guesing some1 had taken there child to river way sick and maybe did not no and it was in the water?!?!

While were discussing sickness i really really hate when people take there chilcren to public places to play such as (lollipops) when they are clearly sick snotty nose etc YUK
