Febris

Febris was the Roman goddess of fever. She would give people fevers and also protect them from malaria. Ancient Roman people were scared of her and wish her to not to do harm. 
Febris was described as honest and shrewd. She was invoked with the formula "Febris diva, Febris sancta, Febris magna" (Goddess Fever, Holy Fever, Great Fever). Febris had two daughters named Dea Tertiana and Dea Quartiana who were goddesses of fevers that are caused by malaria. Febris may have originated from Februus the god of purification.
