Low white blood cell count (WBC), also known as leukopenia, can be caused by various infections. Here are some common examples:
Viral Infections
- Influenza: Commonly known as the flu, this viral infection can cause a decrease in WBC count, particularly neutrophils.
- Measles: This highly contagious viral disease can lead to a temporary drop in WBC count.
- HIV/AIDS: The human immunodeficiency virus (HIV) attacks and weakens the immune system, leading to a decrease in WBC count, including CD4+ T cells.
- Epstein-Barr Virus (EBV): Mononucleosis, caused by EBV, can lead to a decrease in WBC count, particularly lymphocytes.
Bacterial Infections
- Typhoid Fever: This serious bacterial infection caused by Salmonella Typhi can lead to a decrease in WBC count.
- Sepsis: A life-threatening condition caused by the body's overwhelming response to infection, sepsis can lead to a decrease in WBC count.
- Tuberculosis: This chronic bacterial infection can cause a decrease in WBC count, particularly lymphocytes.
Parasitic Infections
- Malaria: This mosquito-borne parasitic infection can cause a decrease in WBC count, particularly neutrophils.
- Toxoplasmosis: This parasitic infection can cause a decrease in WBC count, particularly lymphocytes.
It's important to remember that a low WBC count can also be caused by other factors, such as certain medications, autoimmune diseases, and bone marrow disorders. If you are experiencing symptoms of low WBC, it is essential to consult a healthcare professional for proper diagnosis and treatment.
