HOW LONG ARE COLD SORES CONTAGIOUS?
If you’ve ever experienced a cold sore, odds are you’ve done some research on the topic. You likely know that cold sores are caused by certain strains of the herpes simplex virus (HSV). And you probably also know that cold sores are most often spread through close physical contact, like kissing or oral sex, or shared items such as a eating utensils that have come in contact with the virus.I If you’re looking to help protect your loved ones from HSV infection, this very well may lead you to question just how long cold sores are contagious.
The Mayo Clinic tells us that cold sores are most contagious at the point when blisters are oozing, because the virus easily spreads through contact with infected body fluids.II However, cold sores can be contagious even when you don’t actually see the sores.III Because of this, you should consider your cold sores contagious from the moment you first feel that familiar cold sore tingle to when the cold sore has completely healed.IV When it comes to protecting those around you from cold sores, it’s best to err on the side of caution. Sometimes it can take two to three weeks for a cold sore to heal completely, so you should play it safe that entire time.V
What Should I Do to Protect My Loved Ones?
There are a number of things you can do to help protect the people around you when you have a cold soreVI and they are very simple to put into practice.
- Don’t kiss anyone when you have a cold sore. Kissing is one of the primary ways that HSV is spread. You can avoid that risk altogether simply by not kissing anyone from the moment you feel the tingle until the cold sore is completely healed.
- Don’t share any items that come into contact with a cold sore. HSV doesn’t necessarily require skin-to-skin contact to spread. Avoid sharing items like cold sore creams, towels, cutlery, or lipstick when you have a cold sore.
- Don’t have oral sex. You could potentially give your partner genital herpes if you engage in oral sex before your cold sore is completely healed.
- Don’t touch your cold sore. Other than applying a product like Abreva Cold Sore Cream to treat your cold sore, you should avoid touching it altogether. If, for some reason, you do have to touch your cold sore, be sure to wash your hands immediately afterwards.
