Five to nine days after the symptoms have started, a rash typically begins on the trunk and spreads to the extremities. This rash eventually spreads over most of the body, sparing the face, palms, and soles. Signs of meningoencephalitis begin with the rash and continue into the second or third weeks. Other signs of meningoencephalitis include sensitivity to light (photophobia), altered mental status (delirium), or coma. Untreated cases are often fatal. Causes
Multiple diseases include the word "typhus" in their descriptions. Types include:

Prevention
As of 2020, no vaccine is commercially available. A vaccine has been in development for scrub typhus known as the scrub typhus vaccine. Treatment
The American Public Health Association recommends treatment based upon clinical findings and before culturing confirms the diagnosis. Without treatment, death may occur in 10% to 60% of people with epidemic typhus, with people over age 60 having the highest risk of death. In the antibiotic era, death is uncommon if doxycycline is given. In one study of 60 people hospitalized with epidemic typhus, no one died when given doxycycline or chloramphenicol. Epidemiology
According to the World Health Organization, the current death rate from typhus is about one  of every 5,000,000 people per year.Only a few areas of epidemic typhus exist today. Since the late 20th century, cases have been reported in Burundi, Rwanda, Ethiopia, Algeria, and a few areas in South and Central America.Except for two cases, all instances of epidemic typhus in the United States have occurred east of the Mississippi River.
An ectopic tooth is a tooth that is not located at the dental arch caused by a faulty course during eruption. Ectopic teeth may commonly occur within the dentate region of the jaws. Rarely, the ectopic eruption may occur into the non dentate region, such as the coronoid process, mandibular condyle, maxillary sinus, nasal septum and the palate. == References ==
