Show Notes
Dr. Jessica Pelletier, Dr. Kakande Reagan, and Dr. Bri Bennett discuss the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of onchocerciasis.
Take-Home Points:
- Onchocerciasis is the second leading cause of blindness worldwide
- Transmission occurs via blackfly bites
- Clinical manifestations are typically dermatologic followed by ocular
- Diagnosis ideally occurs via PCR of skin snips, or RDT where this is available
- Treatment is either with ivermectin or doxycycline (which kills the Wolbachia symbiont)
- Prevention on a large scale involves ivermectin MDA, traps, and vegetation clearing, but individuals living in endemic areas need to avoid blackfly bites at all costs
