What viruses cause low WBC?

Conditions that may cause leukopenia Viral infections: Acute viral infections, such as colds and influenza may lead to temporary leukopenia. In the short term, a viral infection may disrupt the production of white blood cells in a person’s bone marrow.

Do low white blood cells make you tired?

This condition may contribute to weakness, fatigue or shortness of breath. Leukopenia: A low white blood cell count. A decrease in the production of functional leukocytes (white blood cells) weakens the body’s immune defense, which may make you more prone to infections. Thrombocytopenia: A low blood platelet count.

How can I increase my WBC and neutrophils?

Eating foods rich in B-12 may help improve low neutrophil blood levels. Examples of foods rich in vitamin B-12 include: eggs. milk and other dairy products….How to raise and lower levelscolony-stimulating factors.corticosteroids.anti-thymocyte globulin.bone marrow or stem cell transplantation.

Can bacterial infection cause neutropenia?

Any bacterial infection can cause neutropenia, but it is most commonly seen in salmonellosis, brucellosis, pertussis, and rickettsial infections. Disseminated tuberculosis is also known to cause neutropenia.

Is 3.8 WBC too low?

How many white blood cells (WBCs) someone has varies, but the normal range is usually between 4,000 and 11,000 per microliter of blood. A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.

Will CBC show bacterial infection?

A CBC test usually includes: White blood cell (WBC, leukocyte) count. White blood cells protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it.

Should I worry about low neutrophils?

When looking at your risk of getting an infection, doctors look at the number of neutrophils you have. If your neutrophil count is low, the doctor may say you are neutropenic. For most people with cancer, having a low neutrophil count is the biggest risk factor for getting a serious infection.

How long can you live with neutropenia?

Chronic neutropenia is defined as lasting more than 2 months. It may eventually go away, or remain as a life-long condition. Some people are born with it (congenital neutropenia), and others develop it as young children.

Can an infection cause low white blood cell count?

A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.

Can bacterial infection increase WBC?

Infection—As infection-causing bacteria or viruses multiply in the blood, your bone marrow produces more white blood cells to fight off the infection. Infection can also lead to inflammation, which can in turn cause the number of white blood cells to increase.

When should I be worried about low white blood cells?

A truly low white blood cell count also puts you at higher risk for infections — typically bacterial infections. But viral infections also may be a concern. To help reduce your infection risk, your doctor may suggest you wear a face mask and avoid anyone with a cold or other illness.

What are the symptoms of having low white blood cells?

If you have a low white blood cell count, you may:Have repeated fevers and infections.Get bladder infections that may make it painful to pass urine, or make you urinate more often.Get lung infections that cause coughing and difficulty breathing.Get mouth sores.Get sinus infections and a stuffy nose.More items…

What WBC indicates viral infection?

Different Types of White Blood Cells Neutrophils are infection fighters that increase during bacterial infections (neutrophils are also known as granulocytes (grans), polys, PMNs, or segs). Lymphocytes, on the other hand, can increase in cases of viral infections.

What WBC count indicates infection?

Normally the total WBC count for an adult ranges from 5,000 to 10,000/mm 3. Leukocytosis (WBC > 10,000/mm 3) can indicate infection, inflammation (possibly from allergies), tissue damage or burns, dehydration, thyroid storm, leukemia, stress, or steroid use.
