History
The name "fifth disease" is not typically capitalized, since the name derives from its historical classification as the fifth of the classical childhood skin rashes or exanthems. Their classification is as follows:
- Measles
- Scarlet fever
- Rubella
- Dukes' disease
- Fifth disease (erythema infectiosum)
- Roseola
It was first described by Robert Willan in 1799 as "Rubeola, sine catarrho". It was better defined by Anton Tschamer in 1889 as a rubella variant ("Ortliche Rotheln"), identified as a distinct condition in 1896 by T. Escherich, and given the name "erythema infectiosum" in 1899.
