Can mono cause low white blood count?

Infectious mononucleosis, commonly known as mono, is a common contagious disease caused by the Epstein-Barr virus. While mono can cause a variety of symptoms, including fever, sore throat, swollen lymph nodes, and fatigue, it is not typically associated with a low white blood cell count.

In fact, mono is more commonly associated with an elevated white blood cell count, particularly an increase in lymphocytes, a type of white blood cell that helps fight infection. However, some people with mono may experience a normal or even slightly decreased white blood cell count early in the course of the disease.

It's important to note that a low white blood cell count can be caused by a variety of other factors, including certain medications, autoimmune disorders, and other infections. If you are experiencing a low white blood cell count, it is important to see a doctor to determine the cause and receive appropriate treatment.
