What are the signs and symptoms of X-linked agammaglobulinemia?

Affected infants are usually healthy for the first few months of life until they begin to develop recurrent bacterial infections. The most common bacterial infections are ear infections, pneumonia, pink eye, sinus infections, and infections that cause chronic diarrhea. These bacterial infections can be severe and life-threatening. Most affected individuals are not vulnerable to infections caused by viruses. Infections can usually be prevented with proper treatment.[1]
