Bloodstream infections
Bloodstream infections (pronounced: blʌdˌstriːm ɪnˈfɛkʃənz) are a type of infection that occurs when bacteria or other organisms are present in the blood. They are a serious condition that can lead to sepsis and other life-threatening complications.
Etymology
The term "bloodstream infection" is derived from the English words "blood", "stream", and "infection". "Blood" comes from the Old English "blod", "stream" from the Old English "stream", and "infection" from the Latin "infectio".
Types of Bloodstream Infections
There are several types of bloodstream infections, including:
- Bacteremia: This is when bacteria are present in the blood but have not yet caused a systemic infection.
- Septicemia: This is a serious, life-threatening infection that can occur when bacteria enter the bloodstream and spread throughout the body.
- Fungemia: This is when fungi are present in the blood, which can lead to a systemic fungal infection.
Causes
Bloodstream infections can be caused by a variety of organisms, including bacteria, fungi, and viruses. They often occur when an infection in another part of the body, such as the lungs or urinary tract, spreads to the blood. They can also occur as a result of a surgical procedure or the use of a catheter or other medical device.
Symptoms
Symptoms of a bloodstream infection can vary depending on the type of organism causing the infection and the individual's overall health. Common symptoms can include fever, chills, rapid heartbeat, and fatigue.
Treatment
Treatment for bloodstream infections typically involves antibiotics or antifungal medications to kill the organisms causing the infection. In severe cases, hospitalization and intensive care may be required.
Prevention
Prevention of bloodstream infections involves good hygiene practices, proper care of wounds and medical devices, and appropriate use of antibiotics.
