The Reality of Oral Transmission of Herpes (HSV2)

Herpes Simplex Virus type 2, commonly referred to as HSV2, is normally not transmitted via the oral route. But the fact remains that a significant number of individuals actually get it through oral contact, more so for people with lower immunity.

Recognizing HSV2 Infections

The typical first symptoms of HSV2 infection are sores and blisters that appear after sexual contact with an infected partner. These physical symptoms are called herpes lesions, which prove that the virus is transmitted by skin-to-skin contact, including every kind of oral contact. This infection is different from other infections that are transmitted only through seminal and genital fluids.

Further, HSV2 is transmitted when an infected individual's body part comes in contact with the mucous membranes or is exposed generally to uninfected individuals.

Oral Transmission of HSV2: Not So Uncommon

Much against common belief, oral transmission of HSV2 does occur and has been recorded worldwide. The major modes of oral transmission include:

  • Skin-to-Skin Contact: HSV2 can be contracted from one person to another during sexual relations, one of which includes oral sex, which is becoming common nowadays.
  • From Sores: The virus is within the body of an infected person even before symptoms appear. It resides in different parts of the body, including the mouth, and can cause sores there. This infection can be contracted by having direct contact with the sores.
  • From Secretions: An infected person may also have secretions coming from body parts, which include the mouth as well as the genitals, that are rich in the virus. These secretions can get the virus during oral sex.
  • Asymptomatic Transmission: HSV2 is transmitted even when the infected individual has no symptoms through the mouth by exchange of saliva.

Symptoms of HSV2 Infection

Symptoms between HSV1 and HSV2 are similar. Some people may have very mild symptoms or no symptoms at all; it is important to recognize that this does not mean the virus is not present and cannot be transmitted. Common symptoms of HSV2 infection include:

  • Painful red sores
  • Irritation of the skin
  • Itching, tingling, and burning sensation around the mouth, lips, or genital area
  • Small, bleeding blisters
  • Headaches, fever, body aches, and pains
  • Swollen glands in armpit, groin, or neck
  • Eye infections
  • Sore throat

Diagnosing Oral HSV2

Oral HSV2 does not show symptoms, but when it does, it shows signs mentioned above. Its confirmation should be done by medical tests if suspected.

Early Symptoms of HSV2

Initial symptoms of HSV2 usually start within the period between two and twelve days after infection. Symptoms create painful blistering around the mouth, lips, and tongue. Blisters and lesions may be most severe around the tenth to fourteenth day after infection.

Rapid Diagnosis with the Use of Rapid HSV2 Test Kits

Testing should be as quick and effective as possible for the early diagnosis and treatment of HSV2. This process has been taken to the next level with the introduction of rapid test kits for herpes, with results taking as little as 15 minutes. These kits work in detecting antibodies that have been created within your blood due to the presence of the virus known as HSV2. Using a small amount of blood, easily derived from a quick finger prick, these test kits provide results in a short amount of time and with good accuracy. This means that in less than a quarter of an hour, you will have clear insight into your HSV2 status to take immediate and appropriate action with peace of mind. Such kits are a milestone ahead in herpes management, offering quick and easy-to-use solutions for people who consider health and time an invaluable asset.

Telling Apart Canker Sores from HSV2

Canker sores and oral herpes are two different conditions. Some of the primary differences include:

  • Cold sores are generally on the roof and gum of the mouth, although canker sores are primarily inside the lips or at the back of the throat.
  • Cold sores heal within a very short time and are smaller in size compared to canker sores.
  • Cold sores generally recur in the exact place, but canker sores will generally develop in different locations inside your mouth.
  • Canker sores start off as red, raised bumps that become larger ulcers, while cold sores appear as clusters of small fluid-filled blisters.

Other Modes of HSV2 Infection

Other than through the oral route, HSV2 infection can be acquired via the following:

  • Vaginal Sex: This is the most common mode of transmission of HSV2.
  • Mother-to-Child Transmission: It can also be transmitted from an infected mother to the baby during pregnancy or at birth because of the exchange of body fluids.

This will result in the infection of the recipient with HSV2 when unscreened blood from an infected individual is transfused.

Mechanisms of Preventing and Treating Oral HSV2

As HSV2 remains incurable at the moment, prevention is better than treatment. These are some major precautions that can be sought:

  • Use of condoms or dental dams during oral sex
  • Reduction in the number of sexual partners
  • Abstinence from sexual activities
  • Regular STI checkups to ascertain your health status and that of your partner

Finally, it's necessary to understand the virus can be transmitted through oral sex. Precautions during oral sex thus need to be taken in order to reduce acquiring or passing on HSV2 infection.
