Signs and symptoms suggestive of neutropenia include: low-grade fever, skin abscesses, mouth sores, swollen gums, and; symptoms suggestive of infections of the skin, perirectal area, mouth, or other areas of the body. Pneumonia is an infection of the lungs that can occur in people with neutropenia.
Causes
Prophylaxis to cover the expected period of neutropenia may be considered for the first cycle of treatment in patients with solid tumors or lymphoma who regularly receive regimens that cause severe neutropenia.

What infections cause low neutrophils count?
What causes a low neutrophil count? Neutropenia is the result of your body destroying neutrophils before your bone marrow can create more. Causes of a low neutrophil count include: Infection (hepatitis, tuberculosis, sepsis, Lyme disease).
Why does neutrophil count decrease in viral infection?
Neutrophils are generally considered to play an essential beneficial role in host defense. They are markedly increased in the circulation and tissues during bacterial or fungal infections, and their decrease (neutropenia) because of genetic defects or chemotherapy leads to recurrent microbial infections [2].

Although viral infections generally do not cause neutrophilia, it can occur during the early phases of infection (see below under "lymphocytosis").
Are neutrophils low with a virus?
1.1 Neutrophils recognize viruses and virus-infected cells and infiltrate into the sites of infection. At the onset of a viral infection, neutrophils are rapidly recruited at the site of infection from the blood and are mobilized to differentiate and migrate out of the bone marrow.
What happens to neutrophils in viral infection?
Neutrophils play multiple roles in acute viral infections. They restrict viral replication and diffusion through phagocytosis, degranulation, respiratory burst, secretion of cytokines, and the release of neutrophil extracellular traps, as well as, activate the adaptive immune response.

What is the lowest neutrophil count?
By many standards, the lowest acceptable limit for adults is about 1,500 neutrophils per microliter of blood. (Some put the cut-off at 1,800 per microliter.)

What is the cause of neutropenia?
Neutropenia Causes. Neutropenia Treatment. People with neutropenia have an unusually low number of cells called neutrophils. Neutrophils are cells in your immune system that attack bacteria and other organisms when they invade your body. Neutrophils are a type of white blood cell. Your bone marrow creates these cells.

What is the name of the disease that causes a low concentration of neutrophils in the blood?
Neutropenia. Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood.

Additionally, acute neutropenia can be commonly seen from people recovering from a viral infection or in a post-viral state.
