Can mold cause sore throat in a 3 year old child?

Yes, but... Molds can cause allergy, and sore throat can be a symptom of allergy. However, it isn't usually the only symptom of allergy you will see: if your child also has ongoing itchy, watery eyes, stuffy nose, and sneezing, those are other possible allergy symptoms. Viruses and "strep throat" are more likely causes if the sore throat has been there a short time, or is the primary or only symptom.
