Systemic infection
Systemic Infection
Systemic infection (/sɪˈstɛmɪk ɪnˈfɛkʃən/) is a type of infection that affects the body as a whole or spreads throughout the body. It is in contrast to a localized infection which affects only a specific part of the body.
Etymology
The term "systemic" is derived from the Greek word "systema" which means "organized whole". "Infection" comes from the Latin word "infectio", meaning "to taint or corrupt".
Definition
A systemic infection is often severe, causing symptoms throughout the body and potentially affecting various organs or systems. It is typically caused by bacteria, viruses, or fungi that have entered the bloodstream, allowing them to spread throughout the body.
Symptoms
Symptoms of a systemic infection may include fever, fatigue, headache, and changes in mental status, among others. The specific symptoms can vary depending on the causative agent and the organs or systems affected.
