What is Herpes?
Herpes is a common viral infection caused by the Herpes Simplex Virus (HSV), which is classified into two main types:
- HSV-1 (Herpes Simplex Virus Type 1): Usually responsible for oral herpes, commonly known as cold sores or fever blisters.
- HSV-2 (Herpes Simplex Virus Type 2): Typically associated with genital herpes affecting the genital and anal areas.
Herpes is a chronic viral infection, meaning that after the initial infection, the virus remains dormant in the body’s nerve cells and may reactivate when the immune system is weakened by stress, illness, or fatigue.
Note: Herpes is not exclusively a sexually transmitted infection. It can also be contracted through direct contact with infected body fluids such as saliva or blister fluid.
Why is Herpes Easily Transmitted?
Herpes is a highly contagious viral infection because the Herpes Simplex Virus (HSV) can be transmitted through direct contact with active lesions, blister fluid, or mucous membranes, even without sexual intercourse.
Common modes of transmission include:
- Direct contact with sores or blisters of an infected person
- Kissing or sharing personal items such as drinking glasses, utensils, lip balm
- Sexual contact without using condoms
- Shared public facilities such as toilets (rare but possible)
The virus can also spread through asymptomatic viral shedding, meaning a person without visible symptoms can still transmit the infection unknowingly.
Note: Not every exposure leads to infection. The risk depends on the individual’s immune response.
Risk Factors for Herpes Infection
Anyone can contract herpes, but certain risk factors can increase the likelihood of both initial infection and recurrence of the virus (herpes outbreak).
Key risk factors include:
- Weakened immune system: Caused by lack of sleep, stress, illness, or chronic disease treatment
- Direct exposure to the virus: Through contact with blister fluid, lesions, or unprotected sexual activity
- High-risk sexual behavior: Having multiple partners, not using condoms
- Sharing personal items: Such as drinking glasses, towels, lip products
- Public exposure: Using shared facilities like public restrooms or gym equipment
For individuals who already carry the herpes virus, these factors may trigger recurrent outbreaks.
Differences Between HSV‑1 and HSV‑2
1. Anatomical Location
- HSV‑1 primarily causes oral herpes such as cold sores around the mouth and face
- HSV‑2 primarily causes genital herpes, affecting the genital and anal areas
2. Prevalence & Epidemiology
- HSV‑1 infection is more widespread than HSV‑2
- According to WHO, about 64% of individuals under 50 carry HSV‑1, while around 13% carry HSV‑2.
3. Recurrence & Asymptomatic Shedding
- HSV‑2 tends to have more frequent recurrences and higher rates of asymptomatic viral shedding in the genital area .
- HSV‑1, especially when causing genital infections, recurs less often and sheds less virus compared to HSV‑2 .
4. Asymptomatic Transmission
- Both HSV‑1 and HSV‑2 can be transmitted through asymptomatic viral shedding
- HSV‑2 shows asymptomatic shedding on 10–30% of days in the first year after infection
5. Treatment & Prevention
- Antiviral medications such as acyclovir, valacyclovir, and famciclovir effectively reduce symptoms and recurrences for both virus types
- Daily suppressive therapy is especially recommended for HSV‑2 patients experiencing frequent genital herpes recurrences
How is Herpes Transmitted?
Herpes is a contagious viral infection that spreads through multiple modes of transmission, including direct contact and sexual activity.
Modes of Herpes Transmission
- Direct skin-to-skin contact: The most common mode, involving contact with active sores or blisters, whether on the mouth (oral herpes) or genital area (genital herpes).
- Kissing or sharing personal items: Such as drinking glasses, straws, napkins, or makeup.
- Unprotected sexual contact: Including vaginal, anal, or oral sex without the use of condoms.
- Perinatal transmission: A pregnant woman with active herpes can pass the virus to her baby during childbirth (neonatal herpes).
When Can Herpes Be Transmitted?
- During active outbreaks: The risk of transmission is highest when visible sores or blisters are present.
- During asymptomatic shedding: The virus can still be transmitted even when there are no visible signs or symptoms.
How is Herpes Diagnosed?
1. Clinical Diagnosis
- Based on medical history and visible lesions, a preliminary diagnosis can often be made by a healthcare provider
2. Lesion Sample Testing (Viral Swab)
- Sample collected from blister or sore fluid for:
- NAAT/PCR: Highly sensitive (90–100%), ideal for detecting HSV DNA from lesions or CSF in encephalitis cases
- Viral Culture: Traditional method but less sensitive, especially for healing lesions
3. Serologic (Antibody) Testing
- Tests for IgG antibodies to HSV‑1 or HSV‑2, indicating past or current infection
- Type-specific assays detect glycoprotein G1/G2, but recent infections require re-testing after ~12 weeks for accuracy
4. Advanced & Modern Techniques
- Point-of-care PCR / Rapid NAAT kits: Provide quick and accurate results directly in clinical settings
- CSF PCR is the gold standard for diagnosing neonatal herpes or HSV encephalitis
Factors Affecting Test Accuracy

What Are the Symptoms of Herpes?
Herpes symptoms can vary from person to person, depending on the type of virus (HSV‑1 or HSV‑2), the site of infection, and the individual’s immune response. In general, symptoms are divided into two categories: primary infection and recurrent outbreaks.
Symptoms of Primary Herpes Infection
- Mild fever
- Body aches
- Burning, itching, or tingling sensation at the affected area
- Small clear blisters forming on the skin or mucous membranes
- Blisters rupture and turn into ulcers or open sores
- Painful burning sensation around the sores
Symptoms of Recurrent Herpes
- Typically milder than the first episode
- Often begins with tingling or itching before blisters appear
- Recovery is usually faster, typically within 5–10 days
Common Affected Areas
- Oral herpes: Lips, corners of the mouth, inside the mouth
- Genital herpes: Genital area, anus, buttocks, groin
How to Prevent Herpes Infection?
While herpes cannot be completely cured, it is possible to prevent initial infection and reduce the risk of recurrence by adopting healthy habits and avoiding risky behaviors.
Preventing Primary Herpes Infection
- Avoid direct contact with infected individuals: Especially when visible sores or blisters are present
- Do not share personal items: Such as drinking glasses, lip balm, or towels
- Use condoms during every sexual encounter: Even when no symptoms are visible
- Maintain good personal hygiene and wash hands regularly
- Avoid kissing or sexual contact during active outbreaks
Preventing Herpes Recurrence
- Get adequate rest
- Manage stress effectively
- Consume a balanced diet and immune-boosting vitamins
