History
- The incubation period of rubella is 14-23 days.
- The prodrome is characterized by the following:
- Malaise
- Fever
- Anorexia
- Headache
- Mild conjunctivitis
- Rhinorrhea
- The rash develops within 1-5 days of symptom onset, starting on the face and forehead and spreading caudally to involve the trunk and extremities.
- The rash tends to clear in the same order as it appeared.
- The rash may be pruritic, but it usually resolves within 3 days without residua.
Physical
- Lymphadenopathy may be present, particularly in the posterior auricular, posterior cervical, and suboccipital chains.
- The rash consists of pink macules and papules, which may become confluent, resulting in a scarlatiniform eruption.
- Petechiae of the soft palate, known as the Forchheimer sign, may be present.
Causes
Rubella is caused by a single-stranded RNA togavirus.
