Several infections can lead to an increase in lymphocytes, a condition known as lymphocytosis. Here's a breakdown of infections known to cause this:
- Acute lymphocytic leukemia
- Babesiosis
- Brucellosis
- Cat-scratch disease
- Chronic lymphocytic leukemia
- Cytomegalovirus (CMV) infection
- Hepatitis A
- Hepatitis B
In essence, lymphocytosis, while sometimes benign, can be indicative of the body's immune system mounting a response to fight off various infections, including both viral and bacterial origins. The specific infection and resulting immune response directly influence the degree and duration of elevated lymphocyte counts.
