This article is for adults. A fever can accompany many illnesses; it does not confirm malaria, typhoid or another diagnosis. If symptoms are worsening or not improving, seek professional assessment rather than repeatedly treating an assumed cause. Seek immediate in-person care for confusion, severe breathing difficulty or other signs of serious illness. Do not wait for every warning sign or a chat response. The sepsis reference explains adult warning signs, but this summary cannot diagnose sepsis or determine that symptoms are safe. Dizziness and fatigue also have many causes: persistent, recurring or disruptive symptoms need assessment. This article does not provide paediatric fever instructions; questions about a child need age-appropriate professional guidance.
