Herpes simplex virus: Understanding its symptoms, outbreak causes, how it spreads and tips for managing the infection

Herpes simplex virus (HSV) is a widespread viral infection that affects millions of people globally. It can occur at any age, and many individuals may carry the virus without showing symptoms, unknowingly transmitting it to others. HSV most commonly infects the mouth or genital areas but can also affect the eyes, fingers, and other parts of the body. Once the virus enters the body, it remains for life, hiding in nerve cells and reactivating periodically, often triggered by stress, illness, or hormonal changes. Recognising the signs of HSV, understanding how it spreads, and following effective management strategies, including medical treatment and lifestyle practices, can significantly reduce discomfort, minimise outbreaks, and prevent transmission to others, helping people maintain better overall health and wellbeing.

What is herpes simplex virus and its types

HSV belongs to the herpesvirus family and exists in two main types:

• HSV-1: Usually causes oral infections, leading to cold sores and blisters around the lips.
• HSV-2: Commonly linked to genital infections, producing blisters and irritation in the genital area.

The virus spreads through direct skin-to-skin contact, including:

• Kissing
• Sexual activity
• Touching infected areas

Transmission can occur even without visible symptoms, making awareness and precaution essential. Once in the body, HSV travels to nerve cells, where it can remain inactive for long periods. Reactivation can be triggered by stress, illness, or hormonal changes.

Common symptoms of herpes simplex virus

Symptoms vary depending on the type and site of infection. Common signs include:

Oral herpes (HSV-1):

• Tingling, itching, or burning sensations around the lips
• Fluid-filled blisters that crust over and heal within a few weeks

Genital herpes (HSV-2):

• Blisters or sores in the genital area
• Discomfort or pain
• Fever or swollen lymph nodes in some cases

Other areas:

• Fingers: Herpetic whitlow, painful blisters
• Eyes: Irritation, pain, and sensitivity to light

Some individuals may carry the virus without noticeable symptoms but can still transmit it. Outbreaks often decrease with age but can be triggered at any time by stress, illness, or other factors.

How herpes simplex virus spreads

HSV spreads primarily through:

• Direct contact with infected skin, blisters, or bodily fluids
• Sexual activity or kissing
• Oral sex, transferring the virus between mouth and genitals

Transmission can occur even without visible sores, as viral shedding can happen without symptoms. Common outbreak triggers include:

• Stress
• Weak immune system
• Hormonal changes
• Fever
• Excessive sun exposure

Understanding these causes is key to reducing the risk of infection.

While there is no cure, HSV can be managed effectively. Key management strategies include:

Medical treatment:

• Antiviral medications reduce outbreak severity and accelerate healing
• Lower risk of transmitting the virus to others

Lifestyle practices:

• Avoid direct contact with active blisters
• Practise safe sex using condoms or dental dams
• Abstain from sexual activity during outbreaks
• Maintain a healthy lifestyle and manage stress
• Get sufficient sleep and follow a balanced diet
• Keep affected areas clean and dry to prevent irritation and secondary infections
