Taï National Park
It is a large park, 4,540 km² (1770 sq mi) of tropical evergreen forest. It is on the UNESCO World Heritage List and is also listed as a UNESCO Biosphere Reserve. It is one of the world's largest protected areas of virgin rainforest and has very diverse flora and fauna.
This forest area is a natural reservoir of the Ebola virus. This is spread by contact with excretions or bodily fluids of infected animals or humans and the main defense is rigorous hygiene. As of early 2014, no vaccine has been approved for humans though there are candidates at various stages of research. Consult a doctor for details if planning a trip.
