acute febrile illness

Acute febrile illness refers to a rapid-onset condition characterized by a sudden fever, often accompanied by symptoms like chills, body aches, fatigue, or headache. It typically indicates the body is fighting an infection, which could be caused by bacteria, viruses, or other pathogens. These illnesses usually develop quickly, last for a short period, and may resolve with or without medical treatment. Because symptoms can overlap with other health issues, proper diagnosis and care are important to identify the cause and determine appropriate treatment.
