Sopona (or Shapona) is the god of smallpox in the Yoruba religion. Shapona was exported to the New World in the slave trade, where he has become known as Babalu Aye, among many other names, in the Orisha religion.
Within the traditional religion of the Yoruba people of Nigeria it is believed that smallpox was a disease foisted upon humans due to Shapona’s “divine displeasure”, and formal worship of the god of Smallpox was highly controlled by specific priests in charge of shrines to the god. Prior to the early 20th century people of this religion believed that if the priests were angered they were capable of causing smallpox outbreaks through their intimate relationship with Shapona. The name "Sapona" (alt. Shapona, Saponna, etc.) is considered a secret and taboo name, not to be spoken aloud in respect for the power of the Lord of Infectious Disease. For this reason, the deity has a number of other names and titles which have been in use since the pre-modern period, such as Omolu.
Dr. Oguntola Sapara suspected that the priests were deliberately spreading the disease, and surreptitiously joined the cult. He discovered that the priests were causing the disease through applying scrapings of the skin rash of smallpox cases. Based on this information, the British colonial rulers banned the worship of Shapona in 1907. Worship continues, however, with the faithful paying homage to the god even after such activities were prohibited.
Sopona is known in the Afro-Brazilian tradition of Candomblé as Sakpata or Sakpata-Omolu in the (Jejé nation). He is associated with the colors red, black, and white, as in Africa. Insects associated with him are Sakpata-Omolu beetles, black butterflies, flies, and mosquitoes. A skirt and hood made of straw that covers the entire body is the clothing associated with Sakpata-Omolu followers and worship. In the Jejé tradition Kpo and Loko are also associated with straw clothing. The xaxará, a broom with palm or straw bristles, is used in Sakpata-Omolu rituals. Small gourds, white cowry shells, a black necklace (laguidibá) are all clothing associated with Sakpata-Omolu. He is seen to have both the power to inflict and cure skin disease and other contagious diseases. In present times this includes AIDS.
In the Trinidad Orisha tradition Sopona is known as Shakpana, and is similarly a ferocious god associated with healing smallpox. In a survey of Orisha shrines on Trinidad James Houk found that flags to Ogun are found in almost every location; those to Shakpana and Osain (Osanyin) closely follow in popularity.
