Lymphocytes are a type of white blood cell crucial for the immune system. Certain infections can trigger an increase in lymphocyte count, a condition known as lymphocytosis.
Here are some infections that commonly increase lymphocytes:
- Viral infections: Many viral infections, such as mononucleosis (caused by Epstein-Barr virus), cytomegalovirus (CMV) infection, HIV infection, and influenza, lead to an increase in lymphocytes.
- Bacterial infections: While less common than viral infections, some bacterial infections, including whooping cough (pertussis) and tuberculosis, can also cause lymphocytosis.
- Parasitic infections: Infections caused by parasites, such as toxoplasmosis and malaria, can lead to an elevated lymphocyte count.
- Autoimmune diseases: Some autoimmune diseases, such as rheumatoid arthritis and lupus, can also be associated with lymphocytosis.
It's important to note that an elevated lymphocyte count is not always a sign of infection. Other factors, such as stress, medications, and certain medical conditions, can also contribute to lymphocytosis. If you are concerned about an elevated lymphocyte count, it's essential to consult a healthcare professional for proper diagnosis and treatment.
