Sexually transmitted infections (STIs) are often associated with bacteria or viruses, but certain fungal infections can also spread through sexual contact. While less common, these infections are increasingly recognised, especially with the emergence of newer strains.
Common Sexually Transmitted Fungal Infections
Fungal infections are typically caused by organisms that thrive in warm, moist environments. Some of these infections can spread during close skin-to-skin or sexual contact, especially when the genital area is involved.
One of the most recognised fungal infections in this category is Candidiasis, commonly referred to as a yeast infection. Although not strictly classified as an STI, it can be passed between partners during sexual activity. Another relevant group includes dermatophyte infections such as Tinea cruris. These affect the groin and may spread through direct contact. While often linked to hygiene and environmental factors, sexual transmission is possible.
More recently, attention has shifted towards emerging fungal infections that show clearer patterns of sexual transmission, including TMVII.
What You Should Know About TMVII
TMVII refers to a strain of Trichophyton mentagrophytes type VII, an emerging dermatophyte that has been increasingly reported in multiple countries, including the US. Unlike typical fungal infections, TMVII has shown a stronger association with sexual transmission.
This infection often affects the genital, groin, and surrounding areas, making it more likely to spread during intimate activity. It has raised concern among public health experts due to its persistence and potential resistance to standard treatments.
How They Spread
Transmission may occur through:
- Genital-to-genital contact
- Contact with infected skin in the groin, thighs, or buttocks
- Sharing contaminated items such as towels (this is less common)
In the case of TMVII, studies suggest that intimate contact is a key driver.
Risk Groups
- Individuals with multiple sexual partners
- People engaging in unprotected sexual contact
- Those with weakened immune systems
- Individuals living in warm, humid climates
Symptoms
- Red, itchy rashes in the groin or genital area
- Scaly or well-defined skin patches
- Burning or discomfort, especially with friction
- In some cases, spread to nearby areas such as the thighs or buttocks
TMVII infections may present as more persistent or widespread rashes that do not respond easily to standard antifungal treatments.
Note: Most of the time, symptoms of STIs overlap with other infections, so evaluation is important rather than relying on self-diagnosis.
How They Are Diagnosed
Diagnosis typically involves a clinical examination followed by laboratory testing to confirm the presence of fungal organisms. Healthcare providers may use:
- Skin scrapings are examined under a microscope
- Fungal cultures to identify the specific organism
- Molecular tests in more complex or resistant cases
Identification is especially important for TMVII, as treatment may differ from standard fungal infections.
TMVII Treatment Options
Treatment depends on the type and severity of the fungal infection. Common treatment approaches include:
- Topical antifungal creams for mild infections
- Oral antifungal medications for more extensive or resistant cases
- Maintaining proper hygiene and keeping affected areas dry
For TMVII, treatment may require longer courses or alternative antifungal agents, especially if resistance is suspected. Medical supervision is important to ensure the infection is fully cleared.
Patients are also advised to avoid sexual contact until treatment is completed and symptoms have resolved, to prevent reinfection or spread.
