Rubella, also known as German measles or 3-day measles, is a mild often exanthematous disease of infants and children that is severe and associated with complications in adults. It is self-limiting disease associated with a characteristic maculopapular rash.
It is caused by a single-stranded RNA virus classified as a togavirus, genus Rubivirus.
Transmission is through airborne or droplets shed from respiratory secretions.
Highly communicable at the onset of the rash, however viral shedding may also occur 5-7 days before, to 5-7 days or more following appearance of the rash.
The incubation period is 14-21 days.
A 4-week course of amoxicillin-clavulanate in children with protracted bacterial bronchitis (PBB) does not improve cough resolution rates compared with a 2-week course, according to a study from Australia. However, the longer course may significantly extend time to first cough exacerbation.
