What causes herpes on the lips?

Lip herpes is an infectious disease caused by the herpes virus, which is very harmful to human health. It often causes respiratory tract infections in patients, causing symptoms such as fever and high chills. It also often causes erythema and papules, and ulcers. There are many reasons for this disease, the most important of which is the herpes simplex virus. In addition to regular treatment, daily conditioning is also very important.

1. Causes

1. Cold sores are caused by the herpes simplex virus

Small blisters form on and around the lips. Generally, the initial infection is not easy to notice and sometimes causes gingivitis. After the initial infection, the virus lies dormant in nerve cells and causes cold sores when activated.

2. This disease is caused by the herpes simplex virus, a DNA virus.

Type I causes infections primarily of the skin, mucous membranes (oral mucosa), and organs (brain) other than the genitals. Type II mainly causes skin and mucous membrane infections in the genital area. The virus enters the body through the respiratory tract, oral cavity, genital mucosa and broken skin, and resides in the normal mucosa, blood, saliva and sensory ganglion cells of the human body. When the body's resistance is reduced, such as when experiencing fever, gastrointestinal dysfunction, menstruation, pregnancy, focal infection, lack of sleep and mood changes, latent HSV in the body is activated and the disease occurs.

2. Home Care

1. Relax

When symptoms occur, you can reduce stress by doing some relaxing exercises. For example, listening to music, taking a walk, swimming, etc.

2. Keep the affected area dry

If your cold sore isn't too serious, you may want to ignore it. But make sure the cold sore is dry, and if an abscess develops, see a doctor to determine the extent of the bacterial infection.

3. Change your toothbrush

The herpes simplex virus can live on your toothbrush for a while, making you susceptible to reinfection after you recover. Throw away your toothbrush when you notice that you have a viral infection again. If you still get cold sores, throw away your toothbrush after the blister forms. This can prevent multiple herpes outbreaks. Once the herpes has completely healed, change your toothbrush.

4. Keep your toothbrush dry

A damp toothbrush and a humid bathroom are just the right amount of comfort for herpes simplex. This moisture helps extend the life of the virus in your toothbrush. Therefore, it is recommended to store your toothbrush in a dry place.
