Almost 90 percent of the people carry the virus. The transmission takes place through a droplet or smear infection and often takes place in childhood. In most cases, the viruses enter the body through direct contact with infected saliva, for example when kissing, but also through the air we breathe to cough or sneeze. The herpes virus then travels through nerve tracts to a nerve node in the brain that lies directly above the ear – the so-called trigeminal nerve.

The initial infection usually goes unnoticed. However, the virus can become active at any time – which is the case in around a third of those affected. Whether and when an outbreak occurs depends on various factors. Usually a weak one plays immune system the crucial role. The main triggers for herpes are:

Many patients also report that they are with them Herpes from disgust forms. When the herpes simplex virus becomes active, it travels through the nerve pathways to the source of the primary infection. If the lip is affected, one speaks of herpes labialis. As a result of the rapid multiplication of the viruses, the highly contagious vesicles form, which itch and burn. These are usually only visible two to three days after the viruses have started to march back.

  • Tingling, itching and tension in the area of ​​the lips
  • Redness of the skin
  • Formation of painful cold sores in the area of ​​the lips, nose or eyes

The advantage of the plasters: since the blisters are covered, the risk of infection is also reduced.

Herpes is highly contagious from the first feeling of tension. Spreading is further promoted by contact with the hands. Regular and thorough hand washing also helps prevent the virus from spreading.

Duration of infection: When to the doctor?

If left untreated, the blisters usually clear up after seven to ten days without scarring. However, if the infection does not improve after five days or if it occurs more than six times a year, a visit to the doctor is necessary. This is also advisable if the blisters spread over the face, cause severe pain, or if the patient has diabetes and cancer. In case of severe infestation, cortisone preparations can be used or active ingredients such as acyclovir can be taken in the form of tablets.

Before the immune system has brought the infection under control, the pathogens withdraw into the nerve cells and can lead to a new outbreak at any time. Most of them get mouth sores two or three times in their lifetime. For some, the blisters also appear two to three times a year. In extreme cases, there can be an outbreak every month. Still others are infected with the virus, but never suffer from herpes.

  • Make sure that no one else is using your used towels, glasses or cosmetic products such as lipsticks and lip balm.
  • After healing, towels and bed linen should be washed and toothbrushes and cosmetic products replaced.
  • Special care is required when dealing with babies and toddlers, as their immune systems are still very weak. Avoid skin contact and use a face mask for safety.
  • If you wear contact lenses, you should wash and disinfect your hands thoroughly before inserting them to avoid spreading them into the eyes.
