Hi, thanks for using healthcare magic
It is likely that the both of you may have gastroenteritis
This is usually caused by a virus though there are bacterial causes as well.
It is commonly spread from hand to mouth, so hand washing is key in prevention.
The most important part of treatment is the management of your fluids to prevent dehydration
though this is more common in children than adults. You can concentrate on using fluids for now and restart using dry foods when you feel better.
Your symptoms are in the early phase.
I hope this helps
