Key points
- Donovanosis is a rare but serious bacterial STI that causes progressive genital ulcers.
- Unlike many other STIs, the sores are typically beefy-red and painless initially.
- Prompt treatment with antibiotics is essential to prevent permanent tissue scarring.
- It is caused by the bacterium Klebsiella granulomatis and requires long-term medication.
- Early diagnosis via a UK online doctor or sexual health clinic is vital for recovery.
- Safe sexual practices, including condom use, significantly reduce the risk of transmission.
What is Donovanosis (Granuloma Inguinale)?
Donovanosis, medically known as Granuloma Inguinale, is a chronic bacterial infection that primarily affects the skin in the genital and anal regions. While it is relatively rare in the United Kingdom, it remains a significant sexual health concern due to its progressive nature. It is caused by the bacterium Klebsiella granulomatis.
In the UK, cases are often associated with travel to tropical or subtropical regions where the infection is more prevalent, such as parts of India, Guyana, or South Africa. However, it is essential for British patients to recognise the signs early, as the infection does not resolve on its own and can lead to extensive tissue damage if left untreated. Following NICE (National Institute for Health and Care Excellence) guidelines, a prolonged course of antibiotics is the standard protocol for eradication.
Recognising the Symptoms
The symptoms of Donovanosis differ from more common UK STIs like herpes or syphilis. The most distinct feature is the appearance of 'beefy-red' sores. Characteristics include:
- Painless Ulcers: Small, firm nodules appear first, which then break down into red, velvety granulation tissue.
- Bleeding: The sores bleed easily when touched or rubbed.
- Proximity: The infection usually spreads along the skin folds in the groin and genital area.
- Oodema: In chronic cases, the surrounding tissue may become swollen (oedema).
- Slow Progression: Unlike acute infections, these sores grow slowly over weeks or months, eventually destroying skin and underlying tissue.
Because the initial sores are painless, many patients delay seeking help. However, early intervention is the best way to prevent permanent scarring and lymphatic obstruction.
How is it Transmitted?
Donovanosis is primarily transmitted through vaginal, anal, or oral sexual contact with an infected person. It is considered mildly contagious, meaning repeated exposure is often necessary for the infection to take hold. There is also evidence that it can be transmitted through non-sexual skin-to-skin contact in rare instances, or during childbirth from mother to infant.
The incubation period can vary significantly, ranging from one week to as long as six months. This long window makes it difficult for some individuals to pinpoint when they were exposed. Consistent use of condoms is highly effective at reducing the risk of transmission, though they may not cover all affected skin areas.
Diagnosis and Treatment in the UK
Diagnostic Testing
Diagnosis in a UK clinical setting typically involves a physical examination and taking a 'crush preparation' or biopsy of the lesion. Doctors look for 'Donovan bodies'—distinctive clusters of bacteria inside immune cells—under a microscope. Blood tests are generally not used to diagnose this specific condition.
Treatment Protocols
According to BASHH (British Association for Sexual Health and HIV) and NHS standards, the primary treatment is azithromycin. Other options include doxycycline or erythromycin. Key points regarding treatment include:
- Duration: Antibiotics must usually be taken for at least three weeks or until the sores have completely healed.
- Follow-up: Patients must attend follow-up appointments to ensure the bacteria is fully cleared.
- Partner Notification: Sexual partners should be examined even if they do not have symptoms.
- Abstinence: You must avoid sexual contact until the treatment is finished and the ulcers have resolved.
When to Consult an Online Doctor
Discussing genital skin changes can feel embarrassing, but seeking help quickly is vital. An online doctor provides a confidential and calm environment to discuss your symptoms. You should speak to a GP online if:
- You have noticed a new, painless red sore or lump in your genital area.
- You have recently returned from travel abroad and have developed skin lesions.
- You are worried about the appearance of your skin but are hesitant to visit a walk-in clinic immediately.
- You need advice on which sexual health tests are appropriate for your specific symptoms.
An online GP can assess your history, provide a referral for specialised testing at a local GUM (Genito-Urinary Medicine) clinic, and offer guidance on managing the condition discreetly.
Long-term Complications
If Granuloma Inguinale is ignored, the bacterial infection continues to erode skin tissue. Over time, this can lead to severe scarring and 'elephantiasis' of the genitals due to blocked lymphatic vessels. In very rare, chronic cases, long-standing ulcers have been associated with an increased risk of developing skin cancers in the affected area. Early antibiotic treatment effectively prevents these outcomes.
Red flags — when to seek urgent help
Call 999 or go to A&E if you experience any of the following:
- Severe, spreading infection with high fever and chills.
- Sudden, massive swelling in the groin or genitals that is extremely painful.
- Rapidly spreading skin necrosis (blackening of the skin).
- Inability to pass urine due to swelling or obstruction.
- Heavy, uncontrollable bleeding from genital ulcers.
