You’ve probably heard of cold sores before, but you may not know exactly what they are. Cold sores are small, fluid-filled blisters that commonly appear on or around the lips. They are usually caused by the Herpes Simplex Virus (HSV).
Cold sores are contagious, which means they can be passed from one person to another. They can be passed through direct contact with a cold sore or through contact with saliva, mucus, or other body fluids from someone who has the virus. Cold sores can also be passed to other parts of the body, such as the eyes, fingers, or genitals.
In this post, we’ll answer the question: Are cold sores contagious before they appear? So, let’s find out.
When are Cold Sores Contagious?
Before the Blister Appears
The Herpes Simplex Virus is most contagious during the prodrome stage, which is the time before the blister appears. During this stage, there may be tingling, itching, or burning sensations in the area where the cold sore will appear. The person may also have a fever, sore throat, or swollen lymph nodes. It is important to avoid touching the area during this stage to prevent the spreading of the virus.
During an Outbreak
Cold sores are most contagious when they are in the blister stage. The blisters will usually rupture and release fluid within 24-48 hours of appearing. During this time, it is important to avoid touching the cold sore as well as any items that have come into contacts with it, such as razors, towels, or makeup brushes. It is also important to avoid kissing or sharing utensils with others during this time.
After a Cold Sore Episode
Cold sores are less contagious after they have crusted over but can still be passed to others through skin contact. It is important to avoid touching the area and wash your hands frequently if you do come into contact with it. The virus is transmitted through saliva, so refrain from kissing and sharing any items such as toothbrushes, lip balms, etc., with others.
Prevention and Treatment Options
There are several professional treatments that can be used to prevent or treat cold sores. These include:
Antiviral medications can be prescribed by a doctor and taken orally or applied directly to the cold sore. Examples of antiviral medications include acyclovir (Zovirax), valacyclovir (Valtrex), and famciclovir (Famvir). These medications can help reduce the duration of a cold sore outbreak by one to two days.
Creams and Ointments
These topical treatments can be applied directly to the cold sore to help relieve pain and itchiness. Some examples of creams and ointments that may be effective against cold sores include docosanol (Abreva), benzocaine (Kank-a), and lidocaine (Dynamiclear).
This treatment involves using a laser to destroy the HSV-1 virus. According to one study, laser therapy was found to be effective in reducing the healing time of cold sores by about half when compared to no treatment at all.
Red Light Therapy
This treatment uses red light to activate a special chemical in the skin that helps fight off the virus. Though the evidence is still limited, some studies have found that red light therapy may be effective in reducing the healing time of cold sores.
Home Remedies and Self-Care Practices
In addition to professional treatments, there are also several home remedies and self-care practices that can help prevent or treat cold sores. These include:
Applying a Lip Balm or Cream
Using a lip balm or cream that contains lysine, an amino acid found in many foods, can help reduce the occurrence of cold sores.
Applying a Warm, Damp Cloth
Applying a warm, damp cloth to the area of the cold sore can help reduce pain and swelling.
Restricting Sun Exposure
Sun exposure can trigger an outbreak of cold sores, so it is important to limit time spent in direct sunlight, wear sunscreen, and wear lip balm with SPF when outdoors.
Stress can make cold sores worse, so it is important to practice stress management techniques such as deep breathing, meditation, and yoga.
Frequently Asked Questions (FAQs)
Can you spread cold sores without having any symptoms?
Yes, it’s possible to spread the HSV without having any symptoms of a cold sore. This is because the virus can be present in saliva even when there are no visible signs of a cold sore. In fact, studies have shown that people with HSV can shed the virus for up to six weeks without ever developing any symptoms.
When are cold sores not contagious?
Once a cold sore has crusted over and healed completely, it’s no longer contagious. At this point, the HSV is no longer present on the skin and cannot be spread to others.
Are cold sores contagious after they scab?
Yes, cold sores are still contagious after they scab. The HSV can be present on the skin even when there is no visible blister or scab.
Why do I get cold sores when I’m sick?
Cold sores are most likely to appear when the body is stressed or weakened, such as during an illness. This is because HSV thrives in weak immune systems. Other factors that can trigger cold sores include too much sun exposure or stress.
