Symptoms

• Symptoms of a blood infection include fever, low body temperature, rapid heart rate and breathing, skin rash, joint pain, chills and severe shaking and mental confusion.
  
  

Treatment

• Treatment for blood infections includes oxygen, antibiotics to kill bacteria, blood pressure medication, intravenous saline solution and overnight hospital admission. Severe cases require admission to the intensive care unit.
  
  

Prognosis

• The prognosis after contracting a blood infection depends on age and how soon the infection is treated. Those who are elderly, with poor immune systems and a history of illness have a 20 percent survival rate; healthy people have a 95 percent survival rate.
  
  

Annual Occurrence

• According to the National Centers for Disease Control in Atlanta, only four to five people per 100,000 develop blood infections each year.
