Blood infection, also known as septicemia or sepsis, is caused by germs entering the bloodstream. These germs can be bacteria, viruses, or fungi.
Essentially, sepsis is your body's overwhelming and life-threatening response to an infection. When an infection occurs anywhere in the body, the immune system releases chemicals to fight it. If this response becomes dysregulated and widespread, it can lead to sepsis.
Common Causes of Initial Infection Leading to Sepsis:
Sepsis often starts with an infection in one of these areas:
- Lungs: Pneumonia is a frequent precursor to sepsis.
- Urinary Tract: Infections in the urinary system can spread to the bloodstream.
- Skin: Wounds, cuts, or burns can become infected and lead to sepsis.
- Gastrointestinal Tract: Infections in the stomach or intestines can also trigger sepsis.
Types of Germs That Can Cause Sepsis:
| Germ Type | Examples |
|---|---|
| Bacteria | Staphylococcus aureus, E. coli |
| Viruses | Influenza, COVID-19 |
| Fungi | Candida, Aspergillus |
Progression to Septic Shock:
If sepsis is not treated promptly, it can progress to septic shock. Septic shock is a severe stage of sepsis characterized by a significant drop in blood pressure, which can lead to organ failure and death.
In summary, blood infection is caused by germs entering the bloodstream, triggering an extreme immune response known as sepsis. Prompt treatment is crucial to prevent severe complications, including septic shock and organ failure.
