How is herpes simplex caused? What are the symptoms of herpes simplex? What are the treatments for herpes simplex? For these questions, I believe many people are unaware.
A. How is herpes simplex caused
Human herpes simplex virus is not resistant to the outside world, 56 ℃ heating 30min, ultraviolet radiation 5min, ether and other lipid solvents can be inactivated; but can be in the -70 ℃ environment to preserve its biological activity for a long time.
In an in vitro culture environment, herpes simplex virus can infect almost all kinds of embryonic and neonatal animal-derived fibroblasts and epithelial cells, and quickly produce lesions visible to the naked eye.
Herpes is a common and ancient infectious skin disease; it has been documented even in ancient Greece, and the presence of genital herpes was clinically noted in the 18th century. Since then, the herpes virus has been found to have the characteristics of a latent infection.
Herpes is caused by herpes virus infection, and so is herpes simplex. And the transmission route of herpes simplex is generally the following these.
1, the mouth and lips herpes mainly by saliva (kissing) or parent-child relationship of food transmission and other mutual transmission.
2, pubic herpes is mainly transmitted by intimate contact with each other by the behavior of husband and wife.
3, the skin and mucous membranes of close contact with each other.
4, newborns infected through the birth canal.
Second, what are the symptoms of herpes simplex
I believe we all know that herpes can be in any part of the disease, that suffering from herpes simplex, the patient will appear what symptoms performance?
It is understood that the diagnosis is not difficult for those with typical herpes damage on the surface of the body; for patients whose damage exists only deep in the cavity, such as the genital tract, respiratory tract, and rectum, it is possible to misdiagnose if a comprehensive and careful physical examination is neglected; it is not easy to make a correct clinical diagnosis of a disease such as herpes encephalitis, which only has visceral herpes damage and no herpes on the superficial and easily exposed parts of the body.
Herpes simplex is divided into primary and recurrent
The incubation period of primary herpes is 2 to 12 days, with an average of 6 days. After primary herpes is treated or remits on its own, the virus can remain dormant in the body for a long time and can be activated by fever, ultraviolet radiation, wind, menstruation, trauma, emotional excitement, stress, gastrointestinal dysfunction and other irritating factors, manifesting as recurrent herpes, which often recurs. Many patients with recurrent herpes may have prodromal symptoms before the onset of the disease, such as local abnormalities of sensation.
In addition to a few patients with systemic disseminated infection or herpes encephalitis, herpes simplex mostly presents localized herpetic vesicular damage to the skin mucosa, and systemic symptoms are generally mild, however, relatively speaking, the systemic symptoms of patients with primary herpes are often more pronounced than those of recurrent herpes.
Four, how to treat cytomegalic rash
1.General treatment
The small superficial skin mucous membrane of herpes simplex lesions can be treated with local anti-infective drugs only, for patients with heavy symptoms, especially important organ involvement should be given systemic anti-infective drugs and corresponding symptomatic support treatment, enteric aspirin oral can be used for skin mucous membrane herpes site pain significant, genital herpes during the disease should prohibit conjugal life, for some patients, should be implemented with susceptible people The necessary isolation.
2. Anti-infection treatment
The superficial herpes lesions can be treated with topical medication, such as 3% acyclovir ointment or 0.5% iodoside (idoxuridine) ointment applied to the affected area, and for suspected bacterial infections, topical gentamycin or neomycin ointment can be used.
Five, herpes simplex diet contraindications
It is advisable to eat light products with detoxifying effect, such as: mung bean sprouts, winter melon, cucumber, watermelon, loofah, cabbage, fresh lotus root, marjoram, shepherd’s purse, celery and so on.
Avoid eating spicy and warm foods. Fatty meat, caramel, milk and sweet and other foods, mostly with greasy, fatty and congested nature, easy to make the disease of dampness and heat poisonous evil embedded in the acidic astringent products such as peas, gravy, pomegranate, taro, spinach.
Avoid spicy fish and chicken, dog meat, shrimp, crab, pork, goose meat, sweet and greasy products and other hairy things.
Six, how to prevent herpes simplex
1, newborns, immunocompromised, eczema and other chronic skin diseases, as far as possible to avoid contact with patients with this disease, pregnant women with genital herpes, it is advisable to perform a cesarean section, can avoid infant obstetric infection, genital herpes patients should avoid conjugal life, avoid magnetic therapy can reduce its transmission, recurrent female vaginal herpes to regular cervical smear examination, early detection of cervical cancer.
2, after the emergence of herpes simplex patients in childcare institutions, they should be asked to isolate at home, treatment and healing before returning, pregnant women with genital herpes should be delivered by Caesarean section.
Pregnant women with a recent history of genital herpes should have their amniotic fluid specimens tested for IgM-type HSV antibodies, and a positive result indicates that the fetus has developed an intrauterine infection, so you can discuss with the patient couple whether to consider choosing 0.1% eye drops and isolate them from the affected mother and avoid nursing by the affected mother until the affected mother is cured; during labor and postpartum observation in the hospital, the affected mother and her newborn should be isolated from other women and newborns.
3, adhere to the premarital medical examination system, avoid conjugal behavior, promote safe conjugal life; if necessary, the use of condoms during lovemaking can help control or reduce the prevalence of genital herpes infection, the use of acyclovir immediately after organ transplantation, including bone marrow transplantation, and for patients with frequent recurrence of herpes, try to remove or avoid triggering factors.
All of the above measures can help prevent the occurrence of herpes simplex infection or pre-existing latent sex. The vaccine to prevent herpes simplex is currently in clinical trials.
4. Remember to wash your hands after touching the wound to avoid spreading the virus around by your hands.
5, avoid contact eye kissing, do not share tableware, towels lipstick, oral cleaning products, razors, etc.
6, genital herpes patients should avoid all kinds of conjugal behavior during the attack.
7, genital herpes patients should use condoms throughout the usual conjugal behavior. Even during the non-onset period, the virus of genital herpes patients may still be transmitted to others.
8, female genital herpes patients must not have a recurrence within one year after stopping the medication before they can get pregnant. Studies have shown that pregnant women infected with genital herpes are prone to miscarriage, premature birth or stillbirth, and the mortality rate of neonatal herpes is as high as 50% if the infection is transmitted to the fetus.
