Scarlet fever (sometimes referred to as scarlatina) is an infectious disease characterized by fever, sore throat (pharyngitis), and a characteristic rash. Scarlet fever is predominantly a childhood disease occurring in children 2-10 years of age, though it can less commonly occur in older children and adults. The incidence and mortality rates associated with this once feared disease have significantly decreased due to the introduction and widespread use of antibiotics Cause
Scarlet fever is caused by infection with exotoxin-producing group A beta-hemolytic streptococci (GABHS), notably Streptococcus pyogenes. The release of a particular toxin is responsible for the characteristic scarlet-colored rash seen with scarlet fever (giving the disease its name). In the majority of cases, scarlet fever occurs as a result of a pharyngeal streptococcal infection (strep throat), though it can less commonly occur as result of streptococcal infections at other sites, such as the skin. It is estimated that scarlet fever develops in up to 10% of individuals who develop streptococcal pharyngitis. Scarlet fever can occur at any time of the year, though it is more common during the winter and spring. The streptococcal bacterium is typically spread via airborne respiratory droplets transmitted by infected individuals or by individuals who carry the bacteria but do not experience any symptoms (asymptomatic carriers). Vector
This illness can be caught from contact with the sick person because this germ is carried in the mouth and nasal fluids. The disease can be spread through contact with droplets shed when an infected person coughs or sneezes. If you touch your mouth, nose, or eyes after touching something that has these fluids on them, you may become ill. Also, if you drink from the same glass or eat from the same plate as the...
