What exactly is viral herpes? Viral herpes is a highly contagious disease that requires thorough understanding of its etiology for prevention.
Let's uncover the mystery behind it today.
Viral herpes is a disease. Viral herpes usually arises from the accumulation of toxins in the body, which cannot be excreted normally through metabolism and thus give rise to vesicles. However, the specific causes are still complex.
The following are the possible reasons: 1. The pathogen is Herpesvirus Hominis, which is the sole cause of simplex herpes virus infection and contains DNA as well as the varicella-zoster virus and the common cold virus.
It's not just humans; even many animals, such as rabbits, guinea pigs, cotton rats, and mice can be infected.
Up to now, two types of antigens have been investigated: 1. Herpes simplex virus (HSV-1), which primarily infects the skin and mucous membranes of the mouth, lips, and oral cavity, as well as the central nervous system, and occasionally can be found on the external genitalia.
2. Herpes Simplex Virus Type 2 (HSV-2) usually causes infections in the external genital area or in newborns, but it can also occur as an oral lesion.
This virus generally infects the human body extensively, and minor skin wounds and close exposure to infection sources are prone to infection.
Related viruses can be isolated from the patient's saliva and excrement.
Especially in households with poor hygiene conditions or in kindergartens, infections are particularly susceptible to transmission.
How is viral herpes caused? Viral herpes can occur in any part of the body, and the symptoms vary in different parts, so it is necessary to go to the hospital for examination and treatment.
The specific causes of herpes are as follows:
2. Due to the highly contagious nature of viral herpes, treatment is generally administered through the application of external medications. It is important to avoid the breakage of vesicles, as this can lead to the spread of the infection. If symptoms worsen, it is imperative to seek medical attention and may require the administration of injection-based medication.
Especially for the elderly and children who may be suffering from herpes, it is crucial not to scratch due to the itch. Avoidance of infection is paramount.
Virus herpes generally has the following types, and each type of infection has an appropriate treatment method for everyone to introduce: 1. Simple herpes, also known as "heat sores," usually occurs at the corners of the mouth and on the edges of the lips, or around the nose. The main characteristic is the appearance of clustered small vesicles on the skin's reddish bases, often in clusters.
The blister fluid is clear, but after it matures, it becomes cloudy. Even if healed, it will recur at the original site.
2. Hand, foot and mouth disease is mostly in students and children, especially in three or four years old.
Hand, foot, and mouth disease generally resembles small white spots. The blisters are milky white in color, surrounded by a reddish-brown area.
The main manifestations occur on the surface and bottom of the hands and feet.
Following the rupture of herpetic lesions, there is a slight sensation of pain. About one week later, the treatment will be effective in curing the condition.
3. Herpes zoster will have about five days of pain, then in the body's waist, front chest and back to appear a cluster of small blisters, as blisters increase, the pain is more intense.
Due to their tendency to grow in a band-like manner, they are known as herpes zoster.
A single illness can confer lifelong immunity and prevent recurrence.
The clinical manifestations of herpesvirus include: 1. The incubation period for herpesvirus is from two to twenty days, generally averaging six days.
2. The common symptom is herpetic gingivostomatitis, also known as stomatitis in infants, which is the most common and prevalent type in the early childhood period. It generally appears on the facial cheeks, lips, or within the gums. In some cases, it can also invade the skin around the lips.
At the onset of an outbreak, congestion is initially observed followed by the formation of round papules approximately 2 mm in diameter which then rapidly rupture to form superficial ulcers rich in fibrous exudate.
Sometimes there are localized pains, the most common manifestations of which are emotional irritability and refusal to eat.
In the case of malnourished children or those with deficiencies in immunity, the condition can be severe, leading to dehydration, fever, and acidosis. The body temperature may reach up to 39 to 40 degrees Celsius for three days, lasting about three weeks.
3. Less commonly seen symptoms include corneal conjunctivitis, vulvitis, meningoencephalitis, herpes simplex eczema, systemic infections, and recurrent herpes infections. Although these are not common, it is important to be aware of them so that when they do occur, there is no confusion or misdiagnosis due to incorrect assessment.
Viral herpes diagnosis is based on the determination of whether it is a viral herpes or not, which requires scientific diagnosis.
What are the diagnostic criteria for viral herpes? Here's an overview: 1. Generalized fever and other systemic symptoms in children, along with the appearance of small blister-like rashes on any part of the body, should initially raise suspicions for viral herpes.
At this time, special attention should be paid to the lips and surrounding skin and mucous membranes. If small papules or ulcers are present on both cheeks and gums, a diagnosis of viral herpes can be made.
2. The disease may occur locally and the pathogenic agent can be isolated from four days later.
If the virus isolation is performed without conditions, then it can be observed that a typical eosinophilic inclusion body can be seen on a corneal cell smear.
3. Specimens from the surface of herpetic or ulcerated lesions can be obtained by scraping, and a smear prepared from these specimens can be examined under a microscope for the purpose of confirming the presence of the pathogen.
Utilizing a dual serum test to identify antibodies can be extremely helpful for the diagnosis of primary infections. Generally, it is applicable for patients whose antibody titers exceed fourfold or more than fourfold the levels observed during acute infection phases.
The above is an introduction to medical knowledge about viral herpes, hoping to help improve everyone's further understanding of viral herpes.
