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.
Haematologic disorder, increasing age, malar rash, and autoantibodies are early predictors of arthritis in paediatric patients with systemic lupus erythematosus (SLE), a longitudinal cohort study has shown.
Bifidobacteria supplementation to infant diet helps curb the occurrence of specific bacteria and metabolites during early life, a recent study has shown, adding that no long-term effects have been detected.
