How Can Vomiting Along With Fever And Diarrhea Be Treated?

my son who is 16 years old, 177 lbs, 6 0 feet tall has been mostly bedridden for 40 days. Symptoms include vomiting, fatigue, mild fever, diarrhea off and on, mild sore throat, nausea. Originally he also had a severe ear infection but that cleared up when he completed 2 weeks of antibiotics. None of the other treatments have had any success, including motrin for fever, vitamins for vitamin d or potassium deficiency, smoothies for protein to keep his strength and weight up. Activated charcoal tablets for nausea and to remove any potential impurities in his system. That has caused a very slight improvement in his appetite and skin color. He has not been out of the country nor has he been in polluted or unclean water sources.
