Complications

A Q fever recurrence can affect your heart, liver, lungs and brain, giving rise to serious complications, such as:

• Endocarditis. An inflammation of the membrane inside your heart, endocarditis can severely damage your heart valves. Endocarditis is the most deadly of Q fever's complications.
• Lung issues. Some people who have Q fever develop pneumonia. This can lead to acute respiratory distress, a medical emergency in which you're not getting enough oxygen.
• Pregnancy problems. Chronic Q fever increases the risk of miscarriage, low birth weight, premature birth and stillbirth.
• Liver damage. Some people who have Q fever develop hepatitis, an inflammation of the liver that interferes with its function.
• Meningitis. Q fever can cause meningitis, an inflammation of the membrane surrounding your brain and spinal cord.
