Many causes.: Low WBC can be due to nutritional factors, infections (esp. Viral infections), autoimmune diseases, inhereted defects, leukemias and other bone marrow cancers, meylodysplasia, drug reactions, and even unknown causes. The problem with this is infection, but the risk depends on how low the WBC is. Only with very low WBC is there a risk of death.

Multiple causes: Low production due to bone marrow failure, side effects of some drugs, excessive destruction in auto-immune disorders, enlarged spleen from any cause etc. See this site for more info. http://www.mayoclinic.com/health/complete-blood-count/my00476.

Many: Primary or secondary blood disorder, infection, immunologic diseases, medication, and many other possibilities. Most causes would be treatable. If this has been confirmed then consultation with a hematologist would be appropriate.

Often a virus!: While blood cell count can be low with viral infections. Important to make sure that the red blood cell count and hemoglobin are normal and that the while blood cells are normal in appearance. If wbc, rbc and platelets are low, intervention by hematologist is necessary and may require bone marrow. Low WBC should be followed and return to normal when over the viral infection!

Depends: The primary purpose of white blood cells (wbcs) is to fight infection. So, people with low white blood cell counts could be more susceptible to infections. However, it depends on why the wbcs are low. Some people simply have low WBC counts and live normal lives. Others could have an underlying problem causing the low counts.
Dr. Peter Kurzweil
Internal Medicine 51 years experience
Low white blood cell count is medically known as 'leukopenia' (Latin: leuko=white, penia=paucity or low). {most medical terms have roots in Latin). Other causes could include connective tissue disease (such as systemic lupus erythemattosis--SLE), myelofibrosis of speen and liver, many chemotherapuetic agents (agents which kill the fastest dividing cells, which are usually the cancer cells).
