Onchocerciasis
Onchocerciasis is chronic infection with the filarial worm Onchocerca volvulus, transmitted by repeated bites of infected blackflies.
Key takeaways
- Intense itch, skin nodules, pigment change and eye inflammation develop from parasite larvae rather than a single acute bite.
- Diagnosis uses exposure history with skin snip, eye examination, antibody or other testing according to setting.
- Ivermectin suppresses larvae and must be repeated; it does not reliably kill all long-lived adult worms.
The listings below do not confirm infection; specialist and public-health guidance should assess co-infections and treatment timing.
Skin and eye disease
Chronic inflammation can cause thickened or depigmented skin and lymph-node changes. Larvae crossing the cornea and deeper eye structures can progressively impair sight. Slit-lamp and retinal examination are important when visual symptoms occur.
Treatment and co-infection safety
Community programmes use repeated ivermectin to reduce symptoms and transmission. Doxycycline targeting bacterial symbionts has selected longer-course roles. Heavy Loa loa co-infection can make ivermectin dangerous, so exposure and testing must be reviewed in relevant regions.
When to seek urgent care
Seek urgent eye assessment for new pain, light sensitivity or vision loss. Emergency care is needed for confusion, seizure or reduced consciousness after treatment.
