What causes cold sores?
Cold sores are caused by the herpes simplex virus. There are two
types of the herpes simplex virus. The herpes simplex type 1 virus
(HSV-1) usually causes cold sores, and the herpes simplex type 2
virus (HSV-2) usually causes genital herpes. The actual sores are
similar in appearance for both forms of the virus. It’s also possible
for HSV-1 to cause sores on the genitals and for HSV-2 to cause
sores on the mouth.
Visible cold sores are contagious, but they may be spread even
when they can’t be seen. You can get the herpes simplex virus by
coming in contact with infected individuals. This may happen
through kissing, sharing cosmetics, or sharing food. Oral sex may
spread both cold sores and genital herpes.
Reinfection
Once you get the herpes simplex virus, it can’t be cured but it can
be managed. Once the sores have healed, the virus remains
dormant in your body. This means that new sores can appear at
any time when the virus reactivates. Some people with the virus
report more frequent outbreaks when their immune systems are
weak, such as during illness or times of stress.
