Hi,
All 2 children suffering from similar symptoms like
vomiting, white tongue, the eldest one with fever and dehydration due to vomiting indicate viral infection as the most probable cause.
-
Gastroenteritis due to something in foods or beverages that they have consumed can also cause vomiting.
- There are many reasons for white tongue
like dehydration,
oral thrush.
Changed bacterial flora in intestine.
- The eldest is already admitted means must have been clinically evaluated, investigated and thus proper treated for specific reasons and symptomatically too.
- The other two may need similar treatment.
Strep throat or for that matter any throat bacterial infection can cause manifestation of gastrointestinal symptoms, particularly in children.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
