Varicella Essay

The disease Varicella is a very transmittable disease, as the varicella zoster virus (VZV) causes it. Varicella attacks the human’s nervous system and debilitates it. Like many viruses, VZV, enters the body through airborne viral particles from another infected person. “The new host breathes in the virus, which enters the mucous membrane in a person’s respiratory tract and begins to spread without its envelope from cell to cell” (Dougherty, 2002). Every virus has a specific cell it adheres to and attacks in order to invade the human system, VZV, attacks T cells. “The virus invades T-cells of the blood and those T-cells carry the virus to the skin. There, the virus can recreate its envelope because the top layer of the skin lacks the endosomal…show more content…
Reactivation of latent VZV is associated with cutaneous disease occurring in dermatomes, termed herpes zoster (HZ) resulting in shingles or zoster” (Bloch, 2012). Once Varicella enters the human body is goes into a latent cycle then later reactivates and is shown through out the body and “chickenpox” or shingles. Children or adults who have immunodeficiency disorders do not prevent common infectious diseases. Varicella is a common infectious disease; patients with immunodeficiency disorders resist the vaccine treatment of varicella and it attacks their whole immune system. “Patients who have immunodeficiency disorders rely on immunoglobulin prophylaxis to prevent common infectious diseases. Intravenous immunoglobulin (IVIG) products are prepared from pools of plasma collected from a large number of healthy donors and, therefore, contain antibodies against many infectious agents preventing a variety of bacterial and viral infections, such as varicella, in patients with impaired antibody production” (Nobre, 2015). This is an example of pathogenesis of a patient whose antibodies were not able to attack the Varicella…show more content…
Therefore this is how long it tales for the chickenpox rashes to become visible in ones body before it becomes dormant in the nervous system. Since the varicella zoster virus can cause two diseases, chickenpox (varicella) and shingles (zoster herpes) it causes different signs and symptoms. Many people know that chickenpox causes red rashes/bumps all over the body that produces itchiness and discomfort. The rash usually starts on the face, scalp, or chest, and quickly spreads throughout the body. It usually appears a few days after you have been exposed. Over 4 days, each blister tends to dry out and form a scab, which then falls off 9 to 13 days later (Varicella-zoster virus, 2016). Along with the rashes comes fever due to the body defense mechanism. As for shingles it is a little different. Shingles is the latent reaction that came from chicken pox and the sings and symptoms are slightly different. “The typical shingles rash starts as redness followed by blisters that usually cover only one side of your body. The rash follows the path of the nerve where the virus has lain dormant. Before the rash appears, you will have warning symptoms of pain, usually a sharp, aching, piercing, tearing, or burning sensation, on the part of your body where the rash appears 1 to 5 days later. That area may also feel itchy, numb, and unbearably sensitive to
