Ever heard of flesh-eating STDs? They're not your typical run-of-the-mill infections.

Wondering what these are, how can they be diagnosed, and treated?

Karepedia is here to break down the science and demystify the rumours surrounding these rare and serious infections.

In this blog, we will explore what makes them unique and why it's crucial to understand and prevent them.

By learning this guide thoroughly, let’s make sure we're armed with the info we need to keep ourselves and our communities safe.

What Are Flesh Eating STDs?

Donovanosis has been called the “flesh-eating STD” because it causes thick, ulcer-like sores that can eventually damage genital tissues.

It is caused by a bacterium called transmitted via vaginal, anal, and oral sex.

Care to know the symptoms? Here you go:

  • Widespread ulcers around the genital area and anus

  • Bulging red bumps that may grow in size

  • Painless red bumps that bleed and grow back

  • Damaged skin

  • Loss of genital tissue colour

Causes and Types of Flesh Eating STDs

DiseaseCausative Organism(s)
Necrotizing FasciitisVarious bacteria, such as Streptococcus, Staphylococcus, Clostridium species, including Clostridium perfringens
Fournier's GangreneVarious bacteria, often polymicrobial, including Escherichia coli, Klebsiella pneumoniae, Enterococcus species, Staphylococcus aureus, Streptococcus species
SyphilisTreponema pallidum
GonorrheaNeisseria gonorrhoeae
ChancroidHaemophilus ducreyi
Genital Herpes (HSV-2)Herpes simplex virus 2

It's important to note that while some of these STDs may lead to severe tissue damage and necrosis in rare cases, the term "flesh-eating" is typically associated with severe bacterial infections like necrotizing fasciitis and Fournier's gangrene.

However, viral STDs like Syphilis, and Herpes can still cause painful lesions and ulcers in the genital area.

What Happens If Left Untreated?

When left untreated, nodules and permanent scars may develop. Donovanosis is a rare but potentially severe STI that can pose the risk of long-term complications if left untreated.

Early detection and proper treatment can prevent any long-term issues, such as permanent genital tissue damage.

Necrotising fasciitis is a bacterial infection that affects soft tissue below our skin, it is not an STD, but can progress rapidly through any skin injury like cuts or surgical wounds and can be life threatening.

Diagnosing Them

DiseaseCausative OrganismDiagnostic Tests
Necrotizing FasciitisVarious bacteria, such as Streptococcus, Staphylococcus, Clostridium- Physical examination of affected area - Imaging tests (CT scan, MRI) to assess tissue involvement - Tissue biopsy for bacterial culture and identification
Fournier's GangreneVarious bacteria, often polymicrobial (e.g., Escherichia coli, Klebsiella, Enterococcus)- Physical examination of the genital and perineal area - Imaging tests (CT scan, MRI) for assessing extent of tissue damage - Blood tests for signs of systemic infection (e.g., elevated white blood cell count, C-reactive protein)
SyphilisTreponema pallidum- Blood tests: VDRL (Venereal Disease Research Laboratory) or RPR (Rapid Plasma Reagin) for screening; confirmed by treponemal tests (e.g., FTA-ABS, TP-PA)
GonorrheaNeisseria gonorrhoeae- Urine test (NAAT - Nucleic Acid Amplification Test) - Swab test of affected area (urethra, cervix, throat, rectum) for NAAT - Culture test for bacterial identification and antibiotic susceptibility
ChancroidHaemophilus ducreyi- Swab test of genital ulcers for bacterial culture - NAAT for Haemophilus ducreyi DNA
Genital Herpes (HSV-2)Herpes simplex virus 2- Viral culture of fluid from lesions - Polymerase chain reaction (PCR) test for detecting viral DNA - Blood test for antibodies to HSV-2 (serologic testing)

Treating Flesh Eating STDs

DiseaseTreatment Options
Necrotizing Fasciitis- Immediate surgical intervention to remove necrotic tissue (debridement)
- Broad-spectrum intravenous antibiotics to target causative bacteria
- Supportive care, including fluids and pain management
Fournier's Gangrene- Surgical debridement to remove necrotic tissue and control infection
- Broad-spectrum antibiotics intravenously to target polymicrobial infection
- Supportive therapy, including wound care, pain management, and possibly hyperbaric oxygen therapy
Syphilis- Antibiotic therapy with penicillin G as the preferred treatment
- Alternative antibiotics may be used for penicillin-allergic patients, such as doxycycline or ceftriaxone
Gonorrhea- Antibiotic therapy, typically with a combination of ceftriaxone (injection) and azithromycin (oral)
- Treatment of sexual partners is essential to prevent reinfection and further transmission
Chancroid- Antibiotic therapy with azithromycin or ceftriaxone
- Drainage of buboes (swollen lymph nodes) if present
Genital Herpes (HSV-2)- Antiviral medications such as acyclovir, valacyclovir, or famciclovir for symptomatic relief and suppression of outbreaks
- Counseling on safe sex practices to reduce transmission risk

It's important to note that treatment approaches may vary based on the severity of the infection, individual patient factors, and any underlying medical conditions.

You should always consult with a healthcare provider for accurate diagnosis and appropriate treatment.

Preventing Tips

  • Practise safe sex by consistently using condoms or other barrier methods during sexual activity.

  • Limit sexual partners and choose partners who have been tested for STDs and are free of infections.

  • Get vaccinated against STDs for which vaccines are available, such as HPV (Human Papillomavirus) and hepatitis B.

  • Avoid sexual contact with individuals who have visible symptoms of STDs, such as genital sores or ulcers.

  • Regularly undergo STD testing, especially if you're sexually active with multiple partners or engage in high-risk sexual behaviours.

  • Communicate openly and honestly with sexual partners about STDs, testing history, and prevention strategies.

  • Avoid sharing personal items that may come into contact with bodily fluids, such as razors or towels.

  • Maintain good personal hygiene practices, including regular bathing and washing of the genital area.

  • Seek medical attention promptly if you notice any unusual symptoms or changes in your genital or pelvic region.

Now that we know the ins and outs, it's clear that awareness is our best armour. By understanding these infections, we're better equipped to keep ourselves and our communities safe.

Let's spread the word, have those important conversations, and take charge of our sexual health. With knowledge in hand, we're ready to tackle the challenges and ensure a healthier future for everyone.

Key Takeaways

Oral contraceptives like birth control pills or IUDs don’t prevent STIs.

Using a barrier method like condoms : every time you have sex with a new partner, when you don’t know your partner’s STI status.

External and internal condoms are preferred preventive measures because they help protect you and your partner(s) from exposure to bodily fluids that may contain the bacteria.

Regular screening and open communication with sexual partners.

Seeking immediate medical attention for any unusual symptoms.
