Inflammation is a series of clinical symptoms, such as fever, cough, and diarrhea, caused by the infection of various pathogens and the release of toxins. Inflammation is classified as mild or severe. Generally, mild inflammation has mild symptoms and can be cured with aggressive anti-infective treatment. Severe inflammation can lead to severe clinical symptoms, which can be accompanied by high fever, convulsions, and impaired consciousness. Severe cases can lead to sepsis or even septicemia. Severe infections require higher levels of antibiotics. If the infection is not controlled, it can lead to multiple organ failure or even life-threatening.
