While most prevalent in the southeastern and south central United States, cases have been reported in nearly every state. After flu-like symptoms, a rash typically appears on the fourth day on the wrists and ankles, spreading to the palms and soles. Eventually it spreads to the arms, legs and trunk of the individual. If left untreated, it can cause gangrene to develop. Between five percent and 25 percent of patients die from Rocky Mountain spotted fever.
Early treatment can prevent death.
Meningococcal disease, one of the most common causes of meningitis, is transmitted through respiratory droplets like sneezes or coughs. Outbreaks occur mostly in crowded settings like college dormitories, military settings and other crowded facilities. Most cases occur in the winter and spring in patients younger than 20 years of age, typically those under age five. Ten percent to 20 percent of these patients die. Skin lesions are common and an important early diagnostic clue to this rapidly progressing illness.
