"Cold blisters are so painful"... How are they transmitted? Why do they recur so often?

When you have a cold, have a cold, or are extremely tired or stressed, you may experience blisters around your mouth. These are symptoms of herpes simplex infection (herpes simplex). This is a viral infection that infects the skin and mucous membranes, primarily causing blisters. It is spread through direct skin-to-skin contact and contact with secretions. Let's take a closer look at herpes, focusing on data from the Korea Disease Control and Prevention Agency.

 

Virus invasion through mucous membranes ... Once infected, relapse is frequent

 

Herpes simplex virus is rarely transmitted through the air. Infection occurs primarily through physical contact with an infected person who is shedding the virus from bodily fluids or lesions. The virus invades mucous membranes such as the mouth, throat, cervix, and conjunctiva. Once infected, even after symptoms disappear, the virus can remain dormant in the body's nervous system. Recurrence can occur under stress, inflammation, immunosuppression, or trauma.

Herpes simplex virus types ... 1 brother vs 2 Brother, the difference is ?

 

Herpes simplex virus (HSV) types 1 and 2 exist. According to the Korea Disease Control and Prevention Agency (KDCA), type 1 primarily infects areas above the waist (such as the lips and eyes). Type 2 typically occurs below the waist, particularly in the vulva. Type 1 infection typically causes blisters around the mouth, often associated with extreme fatigue, stress, colds, or body aches. Type 2 infection is characterized by genital herpes, which primarily occurs in the genital area. While infection can occur at any age, it is most common in young adults.

 

Symptoms are ?...  Most commonly occurs at the border between the lips and skin

 

Primary infection with herpes simplex virus type 1 commonly presents as stomatitis or pharyngitis. In adults, adolescents, and school-aged children, primary infection presents as pharyngitis or tonsillitis rather than stomatitis. Blisters appear on the pharynx and tonsils, accompanied by fever, fatigue, headache, and sore throat. Children aged 6 months to 5 years typically present with stomatitis, which is accompanied by severe oral pain and high fever, lasting 2 to 7 days.

Cold sores are the most common symptom of herpes simplex type 1 infection. Blisters most commonly appear at the junction between the lips and the skin, but may also appear on the nose, chin, cheeks, and oral mucosa. Pain, itching, and burning sensations may precede the blisters. They usually heal completely within 6 to 10 days without leaving scars. Blisters can also appear on the conjunctiva and cornea. They typically appear in one eye, and blisters may also appear on the eyelid margin and around the eye. Infections of the fingers and toes are common in young infants and toddlers who suck their thumbs.

 

genital herpes ... infected person 90% The problem is that there are no symptoms

 

Genital herpes most commonly occurs in sexually active adolescents and young adults. Both types 1 and 2 cause the infection. Approximately 90% of those infected are asymptomatic, making the risk of transmission high. Primary infection can cause fever, headache, fatigue, pain, itching, and burning in the genital area. This is followed by numerous blisters and frequent recurrences. Type 2 virus is shed through genital secretions. Caution is advised during sexual contact, especially considering the potential for transmission from mother to newborn. If a genital infection is confirmed just before delivery, the baby will be delivered by cesarean section.

How to treat ?... Use of medications such as acyclovir

 

Most herpes simplex virus infections resolve spontaneously simply by keeping the lesions clean and dry. Skin, mucous membrane, and internal organ infections tend to respond relatively well to antiviral medications. The most commonly used antiviral, acyclovir, inhibits the replication of herpes simplex virus types 1 and 2. However, acyclovir can occasionally cause renal dysfunction (kidney abnormalities) if the patient is not adequately hydrated. It is also ineffective against latent infections, so it does not reduce the risk of future recurrences. Those experiencing frequent recurrences are advised to consult a dermatologist.

 

There is no vaccine yet ... How can it be prevented? ?

 

There is no vaccine yet developed to prevent herpes simplex virus infection. The virus is transmitted through direct skin-to-skin contact and contact with secretions. Prevention includes thorough handwashing and avoiding contact with lesions and secretions. Genital herpes can be reduced by using condoms. It's safer to abstain from sexual contact while blisters are present and for three to four days after they have disappeared. Herpes simplex virus encephalitis is a major cause of viral encephalitis. It can cause personality changes, memory impairment, and speech problems, and delayed treatment carries a high risk of death. Herpes simplex infection should never be taken lightly.

 

=============

It's such a shame there's no vaccine.

I've had herpes on my lips since I was little.

If you feel a little tired, actually

The area around my lips feels a bit ticklish~

 

I hope a vaccine comes out.

 

I think it's because of fatigue and stress.

If you take vitamins, you can prevent it.
