Neutropenia is a blood disorder that can affect anyone. Some people are born with it. It can happen after a viral infection. In some cases the cause can be a side effect of a drug, or exposure to certain poisons. People can get neutropenia when treated for cancer with chemotherapy drugs.
Neutropenia itself often doesn't cause symptoms. In some cases, people only learn they have neutropenia when they have a blood test for an unrelated reason. But people may have other symptoms from infection or the underlying problem causing the neutropenia. Infections can occur as a complication of neutropenia.
