Genital Molluscum Contagiosum: Symptoms, Treatment and UK Support

Molluscum contagiosum is a common viral skin infection caused by the molluscum contagiosum virus (MCV), a member of the poxvirus family. While frequently seen in children as a general skin condition, in adults it is often classified as a sexually transmitted infection (STI) when it appears on the genitals, groin, or lower abdomen.

The infection presents as small, firm, raised papules (bumps) on the skin. They are typically 2mm to 5mm in diameter, pearly or flesh-coloured, and often have a characteristic tiny dimple or 'umbilication' in the centre. While they are usually painless, they can sometimes become itchy, red, or inflamed. In the UK, the incidence of genital molluscum is rising, particularly among young adults, making it a frequent concern for those seeking confidential sexual health advice.

The virus thrives in warm, moist environments and is highly contagious. It is primarily spread through skin-to-skin contact. Because the virus resides on the surface of the skin, condoms may not always provide full protection if the affected skin is outside the area covered by the condom.

Key methods of transmission include:

• Direct sexual contact with an infected partner.
• Sharing personal items like towels, flannels, or razors.
• Autoinoculation: this occurs when you touch or scratch a bump and then touch another part of your own body, spread the virus elsewhere.

According to NICE (National Institute for Health and Care Excellence) guidelines, the incubation period can range from two weeks to several months, meaning you may not notice symptoms immediately after exposure.

In adults, molluscum papules most commonly appear on the penis, vulva, pubic area, inner thighs, or buttocks. You should look for the following characteristics:

• Small, firm, dome-shaped bumps.
• A shiny or pearly appearance.
• A central pit or 'belly button' in the middle of the bump.
• Bumps occurring in clusters or crops.

It is important to distinguish these from other conditions such as genital warts, ingrown hairs (folliculitis), or pearly penile papules. Unlike warts, which have a rough, cauliflower-like texture, molluscum bumps are smooth and firm. If a bump is squeezed, a thick, white, waxy substance may be expressed—however, patients are strongly advised not to do this, as the substance is highly infectious and can cause scarring.

In many cases, the NHS recommends a 'wait and see' approach. This is because the body’s immune system will eventually recognise the virus and clear it without intervention. However, genital cases are often treated to prevent further transmission to partners or for cosmetic reasons.

Over-the-Counter and Prescription Topicals

Several topical treatments are available in the UK. These work by irritating the skin to trigger a localized immune response. Common options include potassium hydroxide (available as Molutrex), which is applied directly to each bump. Other prescription options may include podophyllotoxin or certain creams that help modulate the immune system.

Clinical Procedures

If topical treatments are unsuccessful or the infection is widespread, a GP or sexual health clinic may suggest:

• Cryotherapy: Freezing the bumps with liquid nitrogen.
• Curettage: Scraping the bumps away under local anaesthetic.
• Laser therapy: Often reserved for persistent or severe cases.

Managing the condition at home is crucial to preventing spread. Patients should follow these self-care steps:

• Do not shave: Shaving over the bumps is the fastest way to spread the virus across the skin (autoinoculation).
• Keep it covered: If possible, keep the affected area covered with clothing to prevent skin-to-skin contact with others.
• Avoid sharing towels: Do not share personal hygiene items with anybody else in your household.
• Patience is key: It can take 6 to 18 months for the infection to clear completely. Do not be discouraged if new bumps appear as old ones fade; this is part of the natural cycle of the virus.

A consultation with an online doctor in the UK is an excellent initial step for those who are worried about genital bumps but feel hesitant about visiting a clinic in person. An online GP can provide a confidential assessment based on high-quality photographs or video consultation.

You should seek a consultation if:

• You are unsure if the bumps are molluscum, warts, or another STI.
• The bumps are spreading rapidly or causing significant distress.
• The area has become painful, pus-filled, or looks infected (cellulitis).
• You need advice on which treatments are suitable for use in the sensitive genital area.

Our private GP service provides a discreet environment to discuss your sexual health concerns and can provide private prescriptions for topical treatments where appropriate.
