The herpes labialis, also known as oral herpes, is an infection that usually appears on the lips, although, under certain circumstances, there are cases in which it affects the mouth or gums, being caused by the herpes simplex virus type 1 (HSV-1 ).
Cold sores are famous for their high degree of contagiousnessTherefore, not only does the condition become frequent for those who have already suffered it, but that uncontrolled reproduction is one of the characteristics that distinguishes it from other reactions.
Do you know the causes of cold sores?
In its first episode, the virus that causes cold sores is inactive within nerve tissues, and that is the rationale for why can be reactivated under certain conditions, thus explaining why the treatments are not considered definitive.
On the other hand, it is worth clarifying that herpes simplex type 2 (HSV-2), which produces genital herpes, can be the cause of cold sores when the second person performs oral sex on the first, given that high degree of contagiousness that we mentioned, even among these variants.
So, we can conclude that, by way of prevention, it is convenient to stay as far away as possible from herpes because infected patients, especially with buds in full activity, have a great capacity to infect those around them.
In the same sense, it is important to clarify that, despite the myths about it, cold sores are not classified as a hereditary condition, so the routes of contagion are the previous two.
As a consequence of these contagion routes, the main symptoms that can be noticed have to do with those ulcers or vesicles in the internal or external region of the mouth, accompanied by burning, itching, or slight tingling in the same area.
In its severity, a permanent or swallowing sore throat, fever or low-grade fever, inflammation of the local lymph nodes, etc. can also be diagnosed.
Treatments for cold sores
The most usual treatment against this problem is the use of antiviral medications but, as has already been pointed out, they do not cure the disease, but rather reduce its frequency and intensity.
Especially care requires the pictures in patients with immunosuppression, for example those with HIV, since they are more likely to have this problem, as well as a greater complexity in the development of this discomfort of viral origin.
