When Are Cold Sores Not Contagious?
Cold sores are a common viral infection that affects many people. They're caused by the herpes simplex virus (HSV), and they can be both painful and unsightly. If you have cold sores, you may be wondering when they're not contagious anymore. In this article, we'll discuss the various stages of cold sores and when they're no longer contagious.
Stages of Cold Sores
Cold sores go through several stages before they heal completely. These stages include:Tingling or Itching - This is the first stage of a cold sore and usually lasts for a few hours to a day. During this time, you may feel a tingling or itching sensation around your lips or mouth.Blistering - After the tingling or itching stage, small fluid-filled blisters will appear on or around your lips. These blisters can be painful and can last for several days.Weeping - As the blisters start to break open, they'll release a clear fluid that can be highly contagious. Avoid touching the blister and wash your hands frequently if you come into contact with it.Crusting - Once the blister has ruptured, it will dry out and form a scab. Avoid picking at the scab to prevent scarring and further infection.Healing - After several days, the scab will fall off, and the cold sore will heal. The virus will become dormant again, but it can reactivate in the future.When Are Cold Sores Not Contagious?Cold sores are most contagious during the weeping stage when the blister releases fluid.
