How exactly does the herpes virus hide? How does it live in you forever!
Herpes virus, referred to as herpes, is a viral infection caused by herpes simple virus.This type of infection is classified according to the part of the body where it is infected, and it is mainly divided into two types: oral herpes and genital herpes.Oral herpes often affect the face or mouth, and patients may have small blisters, generally called cold herpes, or symptoms such as sore throat.Genital herpes targets the genitals and may show mild symptoms or small blisters, which after exposure rupture and ulcers, usually heal within two to four weeks.
The initial infection is usually more serious, and may be accompanied by symptoms such as fever, muscle pain, lymphatic gland enlargement and headache.
Herpesviruses alternate repeatedly between active and resting cycles.Over time, the frequency and severity of active symptoms decrease.In addition to oral and genital herpes, the herpes virus may also cause other symptoms such as hands, eyes, and brain, such as herpes finger inflammation and herpes keratitis.According to the type of virus, herpes simple viruses are divided into two types: HSV-1 and HSV-2. The former usually causes perioral infections, while the latter causes genital tract infections.
How ispropagated?
These viruses are usually transmitted through direct contact with the body fluids or the site of the lesion of the infected person.Even without obvious symptoms, the virus may still be transmitted.Genital herpes is classified as a sexually transmitted infection and can be transmitted to babies during delivery.After infection, the virus transports along the sensory nerve to the nerve cells and hides indefinitely there.
The causes of relapse may include decreased immune function, stress and sun exposure.
Oral and genital herpes are usually diagnosed based on the symptoms they appear, but the diagnosis can be confirmed by using virus culture or testing herpes DNA.A blood test can confirm whether you have ever been infected with the virus, but it is negative in a new infection.
Prevention and treatment measures
The most effective way to avoid reproductive tract infection is to avoid vaginal, oral, manual and anal sexual contact during sexual behavior.The use of condoms can reduce the risk, and daily antiviral treatment for infected people can also reduce the chance of transmission.Although effective treatments include the use of acetaminophen and topical lidocaine to relieve symptoms, there is currently no vaccine available and it cannot be cured once it is infected.
The infection rates of HSV-1 and HSV-2 are between 60% and 95% among adults worldwide.
HSV-1 is usually infected in childhood, while the global infection of HSV-2 was approximately 536 million as of 2003, with a high infection rate in women and developing countries.Most people infected with HSV-2 do not know that they have been infected.Since the virus once enters the human body, it will lurk in nerve cells, the proportion of infection increases as it ages.
Pathophysiology of herpes
Infection of herpes virus is often transmitted through direct contact with the body fluids of the active lesions or infected persons.The virus can enter new individuals through tiny skin damage or mucosa of the mouth and sexual organs.Even without obvious symptoms, many infected people still experience virus latency. Commonly within the first year of infection, and during this period, the frequency of asymptomatic transmission reaches 50%.
HSV is a double-stranded DNA virus.
Based on its transmission characteristics, there is currently no method that can completely eliminate the virus, but antiviral drugs can reduce the frequency and severity of attacks.Use of painkillers such as ibuprofen and acetaminophen can relieve pain and fever, while topical anesthetics such as Pricaine and lidocaine can relieve itchy and pain.
Conclusion
Although currently medicine can effectively control the symptoms of herpes and reduce the risk of transmission, it is still necessary to pay attention to the potential of virus latency and recurrence.People should conduct regular testing and maintain good health management to protect themselves and others.Have you ever thought about how to find more effective prevention strategies in this invisible virus world?
