Question 1: Is viral herpes contagious? Suggestion: Hello! Can viral herpes be contagious? Viral herpes is contagious. Herpes simplex virus widely exists in human body, and human is the only host. Patients and carriers are the only sources of infection. In addition to rash and blister fluid, saliva, urine and feces also contain viruses. There are many ways of infection, mainly through direct contact between skin and mucosa. Type ⅱ is mainly through * * *. Because of the prevalence of drug carriers and recessive infections, coupled with many modes of transmission and lack of reliable vaccines, it is difficult to prevent them.

Question 2: Is herpes contagious? Is it a route of transmission?

HSV infection is very common in people, and people are natural reservoir of herpes virus. The main sources of infection are genital herpes patients and asymptomatic virus carriers. Tracing back to the source of male infection, nearly half of them are attributed to prostitutes, and almost all others are from various types of unclean sexual abusers. Patients with genital herpes get infected through sexual contact with their sexual partners, who usually don't know they have genital herpes. This is one of the reasons for the widespread spread of genital herpes.

HSV- 1 is usually transmitted through droplets and saliva, while HSV-2 is almost always transmitted through sexual contact.

The main route of transmission is sexual contact with patients with genital herpes, but asymptomatic carriers with a history of herpes are also the source of infection. Among adults, the positive rate of genital herpes virus antibody is relatively high, generally about 10-70%, which mainly varies with social and economic status and sexual life. According to the survey, among women with low socioeconomic status, the excretion rate of genital herpes virus in * * * is 0.4- 1.33%. It has been found that the excretion rate of genital herpes virus is as high as 12%, and * * * 70% has genital herpes virus. Therefore, the occurrence of genital herpes is obviously related to sexual contact. The disease is highly contagious, and about 60-80% of women who have one-time contact with men with herpes will be infected.

According to the data, kissing with HVS-2 carriers is also easy to infect reproductive herpes under the condition of poor autoimmune. Contact with contaminated items can also be infected, such as using hotel contaminated bedding, bathing, sauna, hot springs and other ways are also prone to genital herpes.

Question 3: Is herpes zoster contagious? Herpes zoster is more common in adults over 40 years old and has severe pain.

Dermatologists say that to understand herpes zoster, we have to start with chickenpox. Herpes zoster is one of the most common viral skin diseases in spring and autumn. After varicella-zoster virus infection, it lurks in the body and attacks repeatedly, resulting in herpes zoster along the innervated skin area, accompanied by neuralgia. The elderly and people with chronic wasting diseases are prone to herpes zoster, and once infected, the condition is more serious. The folk call this disease "waist string dragon", and the literature calls it "waist-winding fire pill", because herpes zoster invades the chest and waist and accounts for more than 60% of this disease. In fact, the disease can also invade the head, face, ears and upper and lower limbs.

Herpes type I mainly spreads through close contact with respiratory tract, skin and mucous membrane, and infects skin, mucous membrane and organs above waist. For example, it can cause inflammation and herpes of oral mucosa, nasal vestibule, conjunctiva and throat. 99% of oral herpes is caused by herpes virus type I infection.

Herpes ⅱ virus mainly exists in female cervix, vulva skin and male urethra, and is the chief culprit of genital inflammation and herpes. According to relevant statistics, 90% of the pathogen of genital herpes is herpes type II virus, and only 10% is herpes type I virus. After contact with sexual organs, it lurks for about 2-20 days (average 6 days). Immunodeficiency, such as immunosuppressants, kidney transplantation, severe burns, severe malnutrition, malignant tumors of blood and lymphatic system, can lead to herpetic eczema, recurrent corneal ulcer, and even systemic disseminated herpes, which is fatal. Neutralizing antibodies and complement-binding antibodies are produced in vivo after 1-3 weeks of infection, and the residual virus may transfer to trigeminal ganglion (herpes virus type I) or sacral ganglion (herpes virus type II) along the nerve axis and enter a static state for a long time.
