Common infections which can cause above-mentioned symptoms are Dengue infection, Chickunguniya infection, Adenoidal infection, Enteric fever, Ricketts infection etc. I would suggest you give plenty of oral fluids with adequate analgesia Paracetamol, which can make her feel a little better. If she is very weak or not taking anything orally or has decreased urine output, then better to consult a pediatrician. Hope I have answered your query. Let me know if I can assist you further.
