Herpes B virus infection

Introduction to B herpes virus infection Herpes is a skin lesion with a confined cavity containing a high liquid surface and is one of the common skin disease symptoms. The diameter of the blister is generally less than 1 cm, and those over 1 cm are bullae. The blister wall is easily broken and is a loose water ring. The blister wall is called a tension blisters. Cancers that occur within the epidermis are called intraepithelial carcinomas, and cancers that occur in the epidermal basement membrane, basal cells, and below are called epidermal vesicles. Diseases in which vesicles can occur are related to skin diseases and systemic diseases, and the causes are complicated. basic knowledge The proportion of illness: 0.03% Susceptible people: no specific people Mode of infection: non-infectious Complications: headache

B herpes virus infection cause

Causes:

BV particles are about 160-180 nm in diameter and consist of envelope and nucleocapsid. The internal linear ds-DNA, its morphological characteristics, virus structure are similar to HSV, and there are more homology between viral antigens.

Pathogenesis:

Human infection with BV is mainly through direct contact with the monkey's infectious saliva or tissue culture, such as bites of infected monkeys, scratches and direct contact with monkey tissues or body fluids, human skin damaged skin contaminated with monkey saliva, or laboratory Operational pollution, etc.

B herpes virus infection prevention 1. Keep your skin clean and take a bath every day. You can wash it 2-3 times a day in hot weather. Clothing should be appropriate, do not sweat too much. 2. Protect the skin from damage, and soften the clothes and bedding. Cut your nails carefully to avoid scratching the epidermis. 3. Avoid contact with people with skin infections and wash hands frequently. 4. Don't be too nervous. Some patients may have bullae, blood blisters and even erosion on the skin, but please don't be nervous. If you treat it for 10 days, you can recover. After the cure, you will not relapse. 5. Take more rest, give a digestible diet and plenty of water. 6. Prevent secondary bacterial infections. Do not rub the affected area to avoid blister rupture. It can be applied to Chinese herbal medicines to promote blister dryness and crusting. 7. Elderly critically ill patients, especially those with herpes zoster on the head and face, are best hospitalized to prevent complications.

The pathogenic effect of BV on humans is much stronger than that of monkeys. The incubation period after virus infection is 2 to 10 years. Once the disease occurs, the condition is serious. Local skin appears erythema, induration, blister formation after 1 to 3 days; systemic symptoms are diverse, including fever. Influenza-like syndrome, especially headache, myalgia, fatigue, etc., may also have lymphadenitis, lymphangitis, oropharyngeal blister-like damage, etc., the condition continues to increase, BV infectious encephalitis can occur, and even life-threatening.

B herpes virus infection check

The isolation of BV from patient blister fluid, tissue homogenate, or the detection of specific antibodies from patient sera is helpful in diagnosis.

Diagnosis and identification of herpes simplex virus infection First, medical history Age-related watery diseases are more common in infantile eczema, congenital large cancerous epidermolysis, Staphylococcus aureus scald-like syndrome, congenital large cancer ichthyosis, and pigment incontinence. The common water cancer diseases in the elderly are herpes zoster, large cancerous herpes, herpes-like dermatitis, and diabetes. 2. The onset of onset of illness with systemic symptoms is seen in large cancerous epidermis-releasing drug eruption, severe erythema multiforme, Staphylococcus aureus scald-like syndrome, large cancerous systemic lupus, chickenpox, Kaposi varicella Rash, erysipelas, snake bites. , bee stings, etc. Diseases that are more acute but have few systemic symptoms, such as contact dermatitis, herpes zoster, herpes simplex, various insect bites, all kinds of bruises, bites, second degree burns, fixed drug eruptions, eczema, etc. A disease with a long onset of illness and generally no systemic symptoms, such as herpes zoster, herpes zoster, herpes-like dermatitis. With large cancer, congenital sputum epidermolysis, acquired cerebral epidermolysis, eczema, hemorrhoids and so on. 3. The patient's genetic history, past history, and medical history can provide diagnostic clues for certain congenital diseases, skin edema of certain systemic diseases, drug dermatitis, and contact dermatitis. Second, physical examination 1. Distribution of water sputum small water sore cluster distribution, more common in pityriasis, herpes zoster, eczema, contact dermatitis, hand, foot and ankle. The distribution of small water sores is more common in chickenpox, Kaposi varicella-like rash, papular and other measles, Coxsackie rash, and acne. Diseases in which small blisters can be aggregated or scattered can be found in eczema, cancer-like dermatitis, hand, foot and mouth disease. The limited distribution of diseases of the genus is found in contact dermatitis, insect bites, sputum, bee stings, snake bites, burns, fixed drug eruptions, diabetic cancer, and contact dermatitis. The systemic distribution of large water sores is found in herpes zoster, herpes zoster, large cancerous epidermis-releasing drug eruption, erythema multiforme and polymorphic erythematous rash, Staphylococcus aureus scalded syndrome, congenital large cancerous epidermium Solution. 2. Nie's sign check Nie's sign positive refers to the pressure on the water sores with finger pressure, the content of water sores with the epidermal uplift and scattered around, this test positive disease is seen in the blisters diagnosis, large cancerous epidermis release drug eruption, Congenital large cancerous epidermolysis, Staphylococcus aureus scalded syndrome.
