Bacteremia is bacteria that has spread to the blood. It can lead to infections when it is not treated. It can also lead to sepsis. This is a severe reaction of the body to the infection.
It is normal to have bacteria in some parts of the body. Small tears or harm can allow it to enter the blood. This can happen from:
- Everyday tasks like toothbrushing
- Some health procedures
- Infections in the body, such as pneumonia

Things that can raise the risk of this problem are:
Most people do not have symptoms. Those who do may have a fever and body aches.
The doctor will ask about your symptoms and health history. An exam will be done.
Your blood will be tested to look for signs of bacteria.
Antibiotics will be used to keep the bacteria from leading to a serious infection or sepsis.
People at higher risk of infection may be given antibiotics before certain medical procedures. This will get rid of bacteria before it can cause problems.
