A low white blood cell count usually is caused by one of the following:
Viral Infections that disrupt bone marrow function
Congenital disorders characterized by diminished bone marrow function
Cancer or other diseases that damage bone marrow
Autoimmune disorders that destroy white blood cells or bone marrow cells
Overwhelming infections that use up white blood cells faster than they can be produced
Drugs that destroy white blood cells or damage bone marrow
It is relatively common for a low lymphocyte count, known as Lymphocytopenia, to occur in children. The temporary occurrence of this issue is usually caused by an infection, such as a cold.

In general, chronic stress is known to lower the function of the immune system, and that would include reducing the lymphocyte count.
it is an indication of bacterial infection
A low neutrophil count along with a high lymphocyte count can be an indication of viral infections, autoimmune diseases and leukemias. That might rule out valley fever.
White Blood Cell count less than 500 places the patient at risk for a fatal infection.
high lymphocyte count leukemia, bleeding anemia lack of iron, bleeding,genetics and poor health
I just tested positive for Lyme disease with similar high lymph count and low WBC. You may want to get tested for Lyme which can cause an array of problems but one of the most common being joint pain.
The term "lymphocyte" can be translated to "white blood cell"--lymphocytes are just one of a few different types of white blood cells in the body. The normal lymphocyte count for an adult is between 1000 and 4800 cells per microliter; lymphocytopenia is a lymphocyte count lower than the norm. Lymphocytes are important to the human immune system, so a low lymphocyte count may mean you're more vulnerable to infection or other problems.
Some infections can occasionally cause a low white cell count. Repeat the count regularly. If it returns to normal no need to worry. If the child also has anemia or low platelet count other investigations will be needed.
Eczema do not cause low white blood cell count.
mumps will cause low sperm count
