Herpes Simplex Virus (HSV), the most common pathogen among humans, is the only natural host for it. HSV infection has become the fourth leading infectious disease in the world.
The main two seroptypes of herpes simplex virus are HS V-1 and HSV-2, which is known as type I and type II.
Let's take a closer look today with the editor to understand what is herpes simplex virus type 1.
Herpes Simplex Virus Type 1, what is it? Human herpes simplex virus is divided into two types: Herpes Simplex Virus Type I (HSV-I) and Herpes Simplex Virus Type II (HSV-II).
Both HSV-1 and HSV-2 viruses are members of the Herpesviridae family, but there are significant differences between them. Let's take a closer look! HSV-1 primarily causes infections in skin, mucous membranes (oral mucosa), and organs (brain) other than the genital area.
Primarily affecting the upper body, it can lead to infections in the oral cavity, lips, eyes, brain, and above the waist. These are often asymptomatic and go unnoticed.
HSV-2 invades the lower body parts, mainly the genital area, and is one of the main pathogens causing sexually transmitted diseases.
As is known to all, such as causing inflammation and herpes in the oral mucosa, nasal vestibule, conjunctiva, throat, and around the mouth, 99% of herpes caused by type 1 herpesvirus.
Alcohol, spicy foods, colds, stress, anxiety, fatigue, sexual activity are the main triggers of HSV-1. It is important to use condoms during sexual intercourse to prevent transmission to your partner. Can general contact lead to transmission?
HSV-1 is transmitted through direct contact, including kissing, touching the oral and respiratory secretions of a HSV-1 infected person.
Symptoms of Herpes Simplex Virus Type 1 primarily include infections outside the genital area, involving skin and mucous membranes (oral mucosa), as well as organs such as the brain. Genital areas, oral cavity, eyes, ears, buttocks, and thighs are all potential sites for infection.
Localized burning and itching.
Herpes simplex is more commonly seen in adults, and generally has a course of 1-2 weeks to heal spontaneously. However, it tends to recur easily.
Herpes simplex virus infection, with symptoms predominantly occurring at the interface of skin and mucous membranes, especially frequently at the corners of the mouth, lips, and nasal cavity.
Initial symptoms of HSV-1 infection generally include: lesions that can occur anywhere on the skin or mucous membranes, most commonly around the mouth, lips, conjunctiva, cornea, and genital areas. There is a sensation of burning, itching, and tension.
Subsequently, erythema appears, followed by the emergence of clustered small blister groups on the affected area or normal skin. The blisters are clear and transparent, later turning cloudy, with a discharge from the eroded areas leading to crusting and scabbing. This may also lead to secondary purulent infection. Lymph nodes near the site may enlarge. The disease can heal in 1-2 weeks, and after recovery, temporary pigmentation scars may persist.
The typical lesion caused by primary HSV-1 infection is gingival and oral inflammation, most commonly observed in infants and young children. Symptoms include restlessness, refusal to eat, fever, swollen gums, and painful oral ulcers.
Can HSV-1 be pregnant with? The body parts affected by HSV-1 are so numerous, can HSV-1 be pregnant with? It is understood that the impact of HSV on fetus and newborn is particularly serious, and the fetal teratogenicity is very high.
Numerous reports indicate that in the early stages of pregnancy, infection with herpes simplex virus can lead to fetal viralemia, spontaneous abortion, stillbirth, congenital anomalies, intrauterine growth retardation or premature birth, as well as being asymptomatic or persistently viremic.
If the test result is positive for HSV-1 IgG, it only indicates that the individual has been infected in the past and cannot indicate whether they are currently infected. If the test result is positive for HSV-1 IgM, it means there is still related virus in the body.
It is recommended to undergo IgM testing. If the result is negative, pregnancy is possible.
Herpes Simplex Virus Type 1 is not considered a sexually transmitted disease (STD). It can indeed occur in the genital area, but it is not classified as an STD. Herpes simplex virus type 1 is a viral infection symptom and does not belong to the category of STDs. However, the second type of infection does fall under the classification of STDs, and while it is generally not contagious through direct contact, there is a possibility of recurrence.
Herpes Simplex Virus Type 1 is generally present in the human body. It can emerge in individuals with weakened immune systems or when they are experiencing conditions of heat, commonly manifesting as vesicular lesions on the lips.
According to relevant statistical data, the pathogen of genital herpes is 90% Type II Herpes Virus and only 10% Type I Herpes Virus.
Following sexual intercourse, symptoms may persist for approximately 2 to 20 days (average 6 days), and individuals with compromised immunity due to immunosuppression, renal transplantation, severe burns, severe malnutrition, or hematologic malignancies may experience exacerbated symptoms following infection. This can result in herpes zoster dermatitis, recurrent corneal ulcers, and even disseminated herpes fatalities.
Generally speaking, there is no need for the patient to worry too much.
