There is no single mode of transmission but there are risk factors associated with bacterial vaginosis:
- douching, tampons left in too long or the IUD
- the multiplication of sexual partners
- the disadvantaged environment
- Unusual vaginal secretions (unusual white discharge), sticky and foul-smelling, and a strong fishy odour on exposure to semen.
Consequences if undetected and untreated
- disturbance of sexual life (related to the impression of a lack of hygiene)
- increased risk of HIV acquisition
- risks of amniotic fluid infection
- risk of miscarriage.
Screening for vaginosis is done via a vaginal smear by a gynaecological professional (only if there are symptoms).
Vaginosis is treated with antibiotics (note: frequent recurrences regardless of sexual activity).
