COLD SORES IN PREGNANCY

Cold sores, sometimes called fever blisters, are groups of small blisters on the lip and around the mouth. The skin around the blisters is often red, swollen and sore. The blisters may break open, leak a clear fluid, and then scab over after a few days. They usually heal after several days to 2 weeks.

What causes cold sores?

Cold sores are caused by the herpes simplex virus. There are two types of herpes simplex virus: HSV-1 and HSV-2. Both virus types can cause lip and mouth sores and genital herpes.
The herpes simplex virus usually enters the body though a break in the skin around or inside the mouth. It is usually spread when a person touches a cold sore or touches infected fluid, kissing an infected person, or touching that person’s saliva.

What are the symptoms?

The first symptoms of cold sores may include pain around your mouth.
After the blisters appear, the cold sores usually break open, leak a clear fluid, and then crust over and disappear after several days.
For some people, cold sores can be very painful.

How are cold sores treated?

Cold sores will usually start to heal on their own within a few days. But if they cause pain or make you feel embarrassed, they can be treated.
Treatment may include skin creams, ointments, or sometimes pills.

How can you prevent cold sores?
  • Avoid coming into contact with infected body fluids, such as kissing an infected person.
