Can't guess: We don't know what made your brother sick. Most common during vacation is food poisoning. I would recommend you watch your diet , eat light , liquids, only cooked dishes, avoid dairy products , except yoghurt. Hope you make back home safe . Happy new year.

Need more info: Where were u vacationing? How long after he ate last did the vomiting begin? Any diarrhea? Anyone else affected? If were in mexico & drank local water or fresh fruit/veggies, u may develop symptoms if u ate/drank them too. If ate same foods elsewhere, might be viral food poisoning (usually self-limiting; just keep hydrated) or possibly hepatitis a. If several family members affected, see fp.
