Variola - Causes, Symptoms and Treatment
Definition Variola is also known as small pox. It is an acute infectious disease caused by a virus named Variola major and Variola minor. No one has naturally contracted smallpox since 1977. Smallpox was declared eradicated from the earth in 1980. Smallpox is a serious, contagious, and sometimes fatal infectious disease. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The significant clinical features include a three-day prodromal illness characterized by fever, headache, backache, and vomiting. A generalized vesicular or pustular eruption in the absence of a severe febrile prodrome is unlikely to be smallpox. At this stage, the person is almost always very sick and not able to move around in the community. The infected person is contagious until the last smallpox scab falls off. Smallpox is most often spread by the respiratory secretions of people with smallpox to people who have closed approximately less than six feet face to face contact. Causes
