What are the symptoms of primary immunodeficiency?

The most common problem for people with primary immunodeficiency disease is that they are more likely to get infections than other people are.  Other symptoms include:

• Having infections more often and getting infections that are more severe, longer lasting, and harder to cure than for people with normal immune systems.
• Getting infected with germs that a healthy immune system would be able to get rid of, known as opportunistic infections.
• Having autoimmune problems, meaning that instead of the immune system attacking germs and disease-causing materials, it attacks the body’s own organs and tissues by mistake.
