Malaria

Malaria was a disease that could be caught in Africa and India during the 19th century.

While on an expedition to the Congo with her husband Professor Cedric Scrivener in 1845, Jane Scrivener died of malaria. (AUDIO: The Ghosts of Gralstead)

In 1886, Clemency Eddison returned from India, claiming to have the disease, and shut herself in her room. In reality, she was pregnant with the Vespiform Arnold Golightly. (TV: The Unicorn and the Wasp)
