Advice For Travellers

Onchocerciasis (River Blindness) is a chronic disease caused by a parasitic worm that is transmitted through the bite of an infected female black fly. These flies usually bite during the day and are found near rapidly flowing streams and rivers. Travellers in areas where this infection occurs should take all precautions to avoid black fly bites.
