Oral Herpes: Symptoms, Triggers, And When To Visit A Doctor

[LoShiNi]

Oral herpes is a condition caused by herpes simplex virus type 1 (HSP-1) and usually manifests in sores (blisters) on the lips (which are often called ‘cold sores’) and in the oral cavity. Burning or tingling sensation in the affected area may precede the outbreak. Blisters can sometimes appear on other areas of the face and the rest of the upper body.Other symptoms may include fever, tiredness, irritability, and muscle aches.


Anyone can contract this virus, regardless of age and gender. There is no clear picture of HSP-1 epidemiology, because many people who have the virus are unaware of it – in some cases, people don’t experience an outbreak after they become infected. More than 90% of people may have HSP-1. Some people have no symptoms at all, but they can spread the virus to others.

The virus is usually spread the following ways:

- person-to-person contact (e.g. by kissing);

- sharing tableware;

- sharing lipstick, etc.

There is no cure for the virus. Once you’re infected, the virus will remain inactive in your body, but you will probably have outbreaks from time to time, caused by the following triggers:

- illness;

- physical or emotional stress;

- fatigue;

- weakened immune system;

- sun exposure or sunburn.

Although there is no cure for herpes, medications that relieve the symptoms and to limit the duration and frequency of outbreaks are available. Your doctor can recommend the treatment that would be best for you.

Contact your doctor if:

- the sores are so painful you can’t eat or drink;

- you developed symptoms of dehydration (reduced urination, dry mouth, drowsiness, irritability);

- you or your child has sores and you are unsure about their cause;

- your very young child has the symptoms;

- your immune system is weakened.
