Thea Litschka-Koen

About a decade ago, Thea Litschka-Koen developed a keen interest in snakes. A CEO of a management company in eSwatini, she embraced her newfound fascination with all that slithers, and immersed herself in studying them. By the late 2000s, she’d completed a set of handling courses, opened a snake-rescue park, and became a (largely self-taught) black mamba expert. Providing snake-removal services, she made her name known locally—and internationally, via a 2009 BBC documentary on her work.

Since meeting Zamo, the first little girl that came looking for help after getting bitten by a snake, Thea Litschka-Koen has become a snakebite activist. She founded the Antivenom Swazi Trust Foundation in 2009, which raises money to buy Antivenom, medical equipment, medical supplies as well as other homecare aids the amputees might need.  Furthermore, in order to improve the knowledge in the medical community, Thea leads symposiums on treatment for local doctors, nurses and paramedics. She was instrumental in writing the current Swaziland Snakebite Treatment Guidelines, the founder of Swaziland Antivenom Foundation, is a co-founder of the Swaziland Snakebite Authority, is a member of the WHO Working Group on Snakebite Envenoming and a member of the National Snakebite Advisory Group.

Together with a band of volunteers taught by Thea, they have tried to reduce snakebite and promote conservation, by focusing on community education as well as the removal and relocation of problematic snakes.

Thea is a member of the National Snakebite Advisory Group
