Viral Infection White Blood Cells

The difference between a bacterial infection and a viral infection can make the difference between a life-threatening and harmless condition, so you might want to read on.

Bacterial infections are caused by bacteria and viral infections are caused by viruses. Okay, pretty simple. Some diseases, such as pneumonia, meningitis and diarrhea, can be caused by both types of pathogens (dangerous microscopic organisms).

White blood cells are produced in the bone marrow – elastic tissue in some of your large bones. Low white blood cell counts are usually caused by:

  • Viral infections that temporarily interfere with the work of the bone marrow
  • Certain disorders present at birth (congenital) involving reduced bone marrow function
  • Cancer or other diseases that damage the bone marrow

White blood cell disorders include a large number of abnormalities affecting white blood cells (WBC), one of three types of blood cells.

  • White blood cells are mostly involved in fighting infections and participating in inflammatory reactions.
  • Red blood cells carry oxygen to the body.
  • Platelets help stop bleeding.

Viral Infection White Blood Cells

How much white blood cell (WBC) a person has varies, but the normal range is between 4,000 and 11,000 per microliter of blood.

Your white blood cell count can be low for several reasons – when something destroys cells faster than the body can replenish or when the bone marrow stops making enough white blood cells to keep you healthy. When your white blood cell count is low, you are very vulnerable to disease or infection, which can be a serious health threat.

Your health care provider can see if your white blood cell count is normal through a blood test known as complete blood count. If your number is too low or too high, you may have white blood cell abnormalities.

A blood test that shows a WBC number of less than 4,000 per microliter (some laboratories say less than 4,500) can mean your body may not be able to fight infection as it should. Low amounts are sometimes called leukopenia.

To calculate and differentiate red blood cells, your doctor needs to take blood samples from you. Blood is usually taken from a vein at the bend of your arm or in your hand. After blood is collected, the blood is sent to the laboratory for analysis.

For patients with acute fever, the presence of a high white blood cell count (WBC) with a ribbon form that increases dogmatically is considered a marker of bacterial infection. However, the current literature does not support this.
