What causes snake ulcers?

Snake vesicle sore is particularly harmful to patients. It often occurs when the patient's immunity is relatively low. This disease is caused by the varicella zoster virus. Generally, children have poor immunity and chickenpox occurs. After good treatment, chickenpox may remain latent. When the body's immunity is poor, the disease may occur. In addition, physical trauma and viral infection are important causes of snake vesicle sore.

What causes snake ulcers?

1. Blisters-Herpes zoster virus causes:

Children with low immunity to this virus may develop chickenpox after being infected. After being infected, some patients become carriers of the virus without developing symptoms, and the virus remains latent until it becomes active again when the body's resistance decreases.

2. Inducing factors.

When the body is injured, damaged by drugs or other contact, the latent virus begins to act, causing hemorrhagic inflammation of the posterior root nerve nodule on one side, and descending neuritis, which causes blisters on the skin of the surrounding nerve separation area. Due to the low resistance of the patient, the virus in the blisters spreads and causes widespread herpes, which are the causes of shingles.

3. Viral infection.

The direct cause of the disease is infection with the herpes zoster virus. The virus enters the human body through the nasal mucosa and invades the tissues of the sensory nervous system. It can enter the cortex along the facial nerves and reproduce in the nerve tissues.

The disease is caused by the varicella-zoster virus. The virus enters the human body through the respiratory mucosa. Spread through blood. Chickenpox appears on the skin. But most people do not develop chickenpox after being infected. It is a latent infection. Become a virus carrier. This virus is neurotropic. After invading the sensory nerve endings in the skin, it can move along the nerve to the ganglion of the dorsal root of the spinal cord. And lurking there. When the host's cellular immune function is low. If you have a cold. fever. Systemic lupus erythematosus and malignant tumors. The virus was reactivated. Causes inflammation of the ganglion. At the same time, the reactivated virus can move along the peripheral nerve fibers to the skin and cause herpes.

Through the above introduction, everyone should have some understanding of the causes of shingles. I hope that after understanding this, friends can do their best to prevent it.
