what is Chickenpox ?


Chickenpox is one of the most dangerous and contagious diseases that each person develops at least once in his lifetime. The disease is very dangerous, but due to the injection of the vaccine, it is very high in the early days after the disease, and it does not cause much problems. Of course, other factors, such as pregnancy or age, are involved in deteriorating conditions.
Chickenpox is a highly contagious infection characterized by skin lesions (varicella zouster rash).
Chickenpox is caused by the Varisla zoster virus, which is a herpes virus family. The virus, after the production of chickenpox, is implanted in all individuals on the pathways of the nerves that come out of the spinal cord, and its reactivity leads to the disease of the shingles or herpes zoster.
The virus is transmitted from the patient through tiny droplets in the air or contact with skin lesions. It is the sole reservoir of the pox virus. A disease is highly contagious, with an infection rate of at least 90% in susceptible individuals. Mainly occurs in the late winter and early spring in temperate regions.
Most of the age group is prone to 5-9 years old. The rest are often children under the age of 15 years. It’s about 10% over 15 years old. In moderate areas, usually 95-90% of the varicella virus is acquired in childhood. The use of immunosuppressive drugs increases the risk of developing the disease.

Symptoms of chickenpox:

The disease usually begins 17 to 14 days after the call (communicative or latent) with a person with chicken pox or shingles.

General symptoms:

Symptoms that are similar to flu symptoms include fever, irritability, abnormalities, headaches, and sometimes mild abdominal pain occurring 1-2 days before skin lesions occur. These symptoms are more common in older children and remain for up to 5-4 days.

Skin lesions:

Skin lesions, which are the main symptom of the disease, first appear on the face and chest, and then the rest of the body is affected. Primary lesions include intense thirsty red maculopapoles, which ultimately turn into vesicles containing clear liquids, then these scaly lesions are closed and recovered. And at the same time different types of lesions are seen on the skin. The lesions can also be found on the throat’s mucous membranes or the genital tract.

Transmission or spread of disease:

The most likely way to get the disease is through the respiratory system and respiratory secretions. Another way of direct contact with skin lesions is in patients with chicken pox or shingles. The transfer rate in family contacts is 90-80%.
The incubation period starts from 48-24 hours before the onset of skin lesions, and until all the vesicles are cracked and dry skin lesions and there is no juicy lesions.
The latent period (commune) is between 21 to 10 days, but usually takes 17 to 14 days.

Complications of chicken pox:

Skin infections:

The most common infectious disease of chicken pox is the addition of secondary bacterial infection to skin lesions. The cause of this infection is scratching them after scratching. Sometimes the blister area remains if the blister is infected.

Lung infections:

The most severe complication is cholera and often affects adults. Usually, 5-2 days after the onset of the disease, symptoms of shortness of breath, coughing and rapid breathing and fever appear and may cause respiratory failure.

Shingles disease:

Sometimes after the course of chicken pox disease, the virus remains dormant in the body (possibly in the root of the nerves near the spinal cord). The sleeping virus may wake up a few years later and cause zoonosis. This disease is due to the activation of Varicella zoster virus in the spinal cord, which is characterized by severe pain and skin lesions.

Other complications:

These include brain or cerebrospinal fluid infections by Varicella sinus virus, inflammation of the heart, cornea, joints, liver and pancreas.
sickness period:
Children’s self-esteem improvement is usually improved within 7-10 days; in adults, this is longer and more likely to occur. After recovery, the person has immunity to chicken pox for life.
