Sepsis—Anthrax

Anthrax is a disease caused by Bacillus anthracis, a germ that lives in soil. Many people know about it from the 2001 bioterror attacks. In the attacks, someone purposely spread anthrax through the U.S. mail. This killed five people and made 22 sick.

Anthrax is rare. It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wool, meat, or hides. It can cause three forms of disease in people. They are

• Cutaneous, which affects the skin. People with cuts or open sores can get it if they touch the bacteria.
• Inhalation, which affects the lungs. You can get this if you breathe in spores of the bacteria.
• Gastrointestinal, which affects the digestive system. You can get it by eating infected meat.

Antibiotics often cure anthrax if it is diagnosed early. But many people don’t know they have anthrax until it is too late to treat. A vaccine to prevent anthrax is available for people in the military and others at high risk.

Sepsis is a serious illness. It happens when your body has an overwhelming immune response to a bacterial infection. The chemicals released into the blood to fight the infection trigger widespread inflammation. This leads to blood clots and leaky blood vessels. They cause poor blood flow, which deprives your body’s organs of nutrients and oxygen. In severe cases, one or more organs fail. In the worst cases, blood pressure drops and the heart weakens, leading to septic shock.

Anyone can get sepsis, but the risk is higher in

• People with weakened immune systems
• Infants and children
• The elderly
• People with chronic illnesses, such as diabetes, AIDS, cancer, and kidney or liver disease
• People suffering from a severe burn or physical trauma

Common symptoms of sepsis are fever, chills, rapid breathing and heart rate, rash, confusion, and disorientation. Doctors diagnose sepsis using a blood test to see if the number of white blood cells is abnormal. They also do lab tests that check for signs of infection.

People with sepsis are usually treated in hospital intensive care units. Doctors try to treat the infection, sustain the vital organs, and prevent a drop in blood pressure. Many patients receive oxygen and intravenous (IV) fluids. Other types of treatment, such as respirators or kidney dialysis, may be necessary. Sometimes, surgery is needed to clear up an infection.
