Herpes, one of which is a yellowish white or translucent small blister on the skin surface, often in groups, filled with fluid.
These symptoms are also seen in conditions such as chickenpox and shingles.
2. This refers to a type of skin disease caused by a virus, commonly affecting the upper lip or face. The symptoms begin with itching and then develop into blisters on the affected area, containing clear fluid and presenting as slightly painful bumps. These will heal after about one to two weeks when scabs form.
Herpes is divided into genital herpes, simple herpes, and varicella.
Today we'll be discussing one of them—herpes simplex.
Herpes is a simple viral skin disease that has been known to humans for thousands of years.
Herpes Simplex is a type of acute herpetic dermatitis caused by the Herpes Simplex Virus and can occur in all parts of the body. Humans are the only natural hosts.
Viruses enter the human body through the respiratory tract, oral cavity, vaginal mucosa, and skin lesions. They reside within the normal mucous membranes, bloodstream, saliva, and sensory ganglia cells of the body.
The etiological agent of herpes simplex virus is the human herpesvirus, which falls under the alpha subfamily of the Herpesviridae. It is classified into two subtypes: HSV-1 and HSV-2. HSV-1 primarily infects regions above the waist, particularly the face and brain tissue, while HSV-2 predominantly affects areas below the waist, such as the genital area, hence its nickname "genital herpes." However, this distinction is not strictly adhered to.
Human Herpes Simplex Virus has a weak resistance to external conditions. It can be inactivated by heating at 56°C for 30 minutes, exposure to ultraviolet light for 5 minutes, and by using ether as an organic solvent. However, it can remain active for a long period at -70°C.
In vitro, herpes simplex virus can infect various embryonic and neonatal fibroblasts and epithelial cells, producing visible lesions within a short period of time. Therefore, the method of isolating the virus in vitro may be used to assist in clinical diagnosis in certain difficult cases.
Symptoms of Herpes Simplex: Everyone might not be very familiar with herpes simplex.
Upon mentioning that herpes can occur in the entire body, what are the symptoms of herpes simplex? Symptoms of Herpes Simplex: 1. Primary infection: The primary infection of herpes simplex can be subclinical, and if clinical symptoms occur, their severity is greater than that of recurrent lesions.
The incubation period is 3-5 days.
Malignant glossitis is the most common primary infection and commonly occurs in children aged 15 years old.
Gingival redness and swelling, easy bleeding. Mucous membranes in the oral cavity including tongue, pharynx, palate, and buccal mucosa present with vesicles, erosions, and ulcers. The ulcers are covered by a pale yellow pseudomembrane, accompanied by fever, discomfort, drooling, restlessness, bad breath, and pain during eating. Local lymph nodes enlarged and painful.
The fever subsides after 3-5 days, and is generally completely resolved within 2 weeks.
2. Genital Herpes: It is more commonly seen in males, affecting the glans penis, prepuce, and shaft of the penis, while females are affected in the external genitalia, vagina, and cervical mucosa. Early on, several red papules and blisters appear with local itching and burning sensation. After blisters burst, shallow ulcers form which subsequently dry and crust over. There may be symptoms such as fever, discomfort, headache, and fatigue, among others, associated with systemic illness.
Without treatment, the duration of the illness continues for 2 to 3 weeks.
Herpes Simplex Infection: Direct viral infection at normal skin or through minor skin abrasions results in the formation of hard papules, large vesicles, or irregularly scattered blisters within 5 to 7 days. Local lymph nodes may enlarge, and systemic symptoms are generally mild.
Inoculation at the fingertips caused herpes zoster, with localized redness and pain, deep vesicles or large blisters.
Recurrent infections of herpes simplex virus are characterized by smaller, more numerous, and less confluent vesicles than primary infections. They generally lack systemic symptoms and frequently do not involve the buccal mucosa.
1-2 hours before rash, local itching or burning sensation, followed by the appearance of grouped vesicles on the base of inflammation, usually heal in 7~10 days without scarring.
The most common sites of involvement are the face, especially the lips, but other parts may also be affected.
Recurrences are generally in the same area, but not always at the same site.
Herpes simplex virus recurrence is extremely common with the presentation of clustered small vesicles and shallow ulcers.
How is herpes simplex caused? After understanding the symptoms of herpes simplex, patients must promptly detect and seek treatment.
However, many people are puzzled as to how herpes simplex virus is caused. Herpes simplex virus infection (40%) is caused by the DNA virus of herpes simplex virus, which is divided into two types: type I (HSV-I) and type II (HSV-II). Type I primarily causes infections in skin, mucosa (oral mucosa), and organs (brain) other than the genital area. Type II mainly causes skin and mucosa infections at the genital area.
Transmission Pathways (20%): The virus enters the body through respiratory tract, oral cavity, genital mucous membrane, and damaged skin. It resides in the normal mucous membranes, blood, saliva, and sensory ganglia cells. When the body's resistance is reduced, such as fever, gastrointestinal dysfunction, menstrual cycle, pregnancy, infected lesion, and emotional changes, the latent HSV is activated and causes disease.
Humans are the only natural hosts of the Herpes Simplex Virus. This virus is present in the vesicle fluid, saliva, and feces of patients, recovered individuals, or carriers. Transmission primarily occurs through direct contact, as well as through contaminated utensils with saliva.
Infectious Source (20%): Clinically, it can be divided into primary herpes simplex infection and recurrent herpes simplex virus infection. Primary herpes simplex infection is caused by contact with herpes simplex patients, with the Herpes simplex virus transmitting through oral-respiratory routes as well as via skin, mucous membranes, and corneal lesions. Patients with active herpes simplex virus infection and asymptomatic excretors have viral particles present in their saliva and feces, thus individuals with herpes simplex infection should avoid contact with other children and infants. The occurrence of recurrent herpes simplex infection is due to activation of latent herpes simplex virus within the body, for which there is currently no ideal method for prevention.
How is genital herpes treated? Genital herpes is a stubborn disease, and it is difficult to cure it completely. Traditional medications have always been ineffective against genital herpes.
The active proteinase in topical balichang drugs is rich, which can quickly dissolve the protein shell of herpes virus, and make the drug ingredients enter into the virus inside quickly, destroy the gene chain.
In addition, antiviral medications are also the primary treatment for herpes simplex virus. 1. Acyclovir (ACV) is a nucleoside analog which inhibits deoxyribonucleic acid synthesis of the virus and has little effect on host cell DNA synthesis.
It is considered to be the most effective anti-HSV medication currently available.
In cases of severe disease, intravenous administration may be employed, with a dosage of 5mg per kilogram body weight administered every 8 hours, for a period of 5 to 7 days.
Patients may take orally 200 mg qid or 800 mg bid for 5-7 days.
It can make the virus decrease rapidly, symptoms lessen and heal time shorten.
Topical application of 3% - 5% ACV ointment can also alleviate symptoms and shorten the duration of the disease.
There is no obvious side effect of this medication.
2. PaiLikang can significantly inhibit the replication of herpesvirus, and has better effects on primary herpes.
3. Pleconaril can significantly inhibit the replication of herpesvirus, and is effective for primary herpes infections.
What medications are used for treatment? Let's take a look together! For severe primary genital herpes and patients with recurrent episodes, non-specific vaccines such as the BCG vaccine and the Poliomyelitis vaccine can be administered to enhance non-specific immunity in the body. However, their effectiveness is not very reliable, and they should be used with caution in patients with immunosuppression or immunodeficiency.
Immunoenhancers may be used for patients with recurrent genital herpes to enhance the immune regulatory function of the body.
For example, Leucovorin, 50mg per dose, three times a day, for three days consecutively, followed by a 11-day interruption.
Levosulpiride may be applied to the flexor forearm by applying a 1% solution of levosulpiride ointment on the flexor forearm, once daily for three consecutive days.
The patient takes medication three times a week.
Traditional Chinese Medicine Topical Application: Topical application of traditional Chinese medicine ointment, Botlikang, can effectively relieve local symptoms within 30 days. Increased exercise is essential to prevent relapse.
Can simple vesicular rash be cured? I have always been deeply impressed by the facial simple vesicular rash, hoping that this condition can be avoided.
Can herpes simplex virus be cured? Doctors recommend seeking treatment at a hospital promptly, without excessive worry. Herpes simplex is treatable.
Erythema infectiosum, commonly known as "hot hives," is a skin disease caused by viruses that typically occurs during the course of febrile illnesses such as colds.
It can occur at any time of the year, including all genders and age groups.
Primary erythema is characterized by a single, often round, lesion that may be as small as a grain or as large as a grain. It presents as red papules with pain and ulceration, resembling blisters. The primary treatment involves symptomatic management and preventing secondary infection.
Topical 2% Gentian Violet Solution, 0.5%, Neomycin Ointment and so on.
Only regular exercise and enhancing immunity are the only methods to cure herpes simplex once and for all.
Is herpes simplex contagious? Understanding herpes simplex naturally involves understanding its contagiousness! Is herpes simplex contagious? In life, how should one prevent herpes simplex? Herpes simplex is an acute herpetic skin disease caused by the Herpes Simplex Virus. Humans are the only natural hosts for this virus. The virus is present in the vesicle fluid, saliva, and feces of patients, recovered individuals, or healthy carriers. The transmission mode is primarily direct contact, but it can also be indirectly transmitted through contaminated utensils with saliva.
Preventing Herpes Simplex virus, there are three points need to be paid attention to: 1. Keep the skin clean and wash it daily. In hot weather, you can wash it twice or thrice a day.
Wear appropriate clothing, avoiding excessive perspiration.
2. Protect the skin from damage, and keep clothes and bedding soft.
Keep your nails short so you don't scratch the skin.
3. Avoid contact with people who have skin infections and wash your hands frequently.
