XX: External causes of morbidity and mortality

The group of conditions classified as "External causes of morbidity and mortality" refers to a wide array of factors outside the body that can lead to illness or death. These factors encompass both injuries and various environmental issues. Injuries can range from cuts and scrapes to more severe types like fractures and burns. Depending on the location and severity, an injury can affect any system in the body and progress variably. Environmental factors include exposure to harmful substances like chemicals or radiation, extreme temperatures, and accidents. Symptoms largely depend on the specific cause, but may include pain, various physical signs like swelling or redness, and systemic issues such as fever or weakness. Disease progression can also be quite diverse, from rapid acute issues to slow, chronic conditions. These causes, while external, can profoundly influence health.
