Cold sores can be spread, even if there are no sores or blisters.


What is labial herpes?

Cold Sores or Febrile Herpes is characterized by the presence of fluid blisters that appear on or around the lips. When the blister breaks, a scab appears, which lasts for several days.

Cold sores are caused by the Herpes Simplex Virus Type 1 (HSV-1) and in some cases, by the Herpes Simplex Virus Type 2 (HSV-2). The two viruses can affect the Lips and Genitals, they can be transmitted by practicing oral sex.


Factors related to the appearance of this virus

- Low defenses

- Stress

- Presence of Cold or Flu

- Prolonged exposure to the sun


For prevention, it is recommended to use moisturizing lip balms and sunscreen, likewise, it is vital that a person prone to get sick with Flu or is under a lot of Stress rest properly to keep their defenses high.


Can Cold Sores be treated?

Cold sores have no definitive cure but outbreaks of blisters can be controlled with antibiotics or antiviral creams, for this it is essential to contact a Specialist, especially if the condition lasts more than 1 week.

Also, for those with Cold Sores, the Dermatologists' instructions are:

1- Do not touch your lips with dirty hands

2- Do not kiss anyone

3- Do not share glasses, cutlery, towels

4- Do not use cosmetics


Cold Sores and COVID-19

Wearing a chinstrap for too long causes moisture, which will delay the healing of a blister or sore. It is vital to change the mask every time it is wet and try to wear it as little as possible, that is, better avoid leaving the house and maintain social distance.
