Hello,
E.coli bacteria infection found in his urine and blood stools mean that hygienic measures while preparing food or changing or using his utensils were not properly taken. Plus, should check the water you use to give to your great grandson as contaminated water is one of the causative agents.
Urinary tract infection might be also related to the fact that babies are not being circumcised.
Treatment is based on antibiotics and by using adequate hygienic measures.
With regards to the dog, if it lives inside their house, then, should test his stool, and allow to live in distance from the baby. The dog might be the carries.
Do follow up with his
pediatrician. Hospitalization is required in case of severe
diarrhea, or if you notice symptoms of a
hemolytic uremic syndrome (HUS): reduced urination, pale skin, unexplained bruises, bleeding from mouth or nose, extreme
tiredness, seizures. All these signs are considered an emergency and require immediate medical attention.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Albana Sejdini, General & Family Physician
