Septicemia can begin with spiking fevers, chills, rapid breathing, and rapid heart rate. The person looks very ill.

The symptoms rapidly progress to shock with decreased body temperature (hypothermia), falling blood pressure, confusion or other changes in mental status, and blood clotting problems that lead to a specific type of red spots on the skin (petechiae and ecchymosis).

There may be decreased or no urine output.

• Low blood pressure

Tests that can confirm infection include:

• Blood culture
• Urine culture
• CSF culture
• Culture of any suspect skin lesion
• CBC
• Platelet count
• Clotting studies
  • PT
  • PTT
