Someone held my 1 year old son yesterday for a few min and today they came down w the stomach bug. where they contagious yesterday, will my son get it?

Exposure: They may have been contagious yesterday. Tim will tell if your child becomes ill.

Virus contagiousness: Yes, that person was likely contagious yesterday. Most people with viral illness begin to secrete the virus a day or two before they actually show symptoms. However, most stomach "flus" are transferred by what we call the "oral-fecal" route. Thus, just holding the child would be unlikely to expose, but if they touched the child's mouth, nose or made their food without good hand wash, could pass it.
