Symptoms may include fever, cough, difficulty breathing, weight loss, night sweats and fatigue. It is most likely to occur when the CD4+ T cell count falls below 200 cells per cubic millimeter of blood.

What treatment would be given for low CD4 count?

A low CD4 count means that HIV has weakened your immune system and may be making you ill. HIV treatment will strengthen your immune system and extend your life. While your CD4 count is low, you may also need to take antibiotics to prevent infections.

How is CD4 calculated?

A CD4:CD8 ratio is calculated by dividing the number of CD4+ T cells by the number of CD8+ T cells; this ratio is usually greater than 1 in immunocompetent individuals [4]. However, in HIV infection, the CD4:CD8 ratio is usually less than 1.
