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.
Baseline body mass index (BMI) and, to a lesser extent, school socioeconomic status are associated with subsequent weight status in schoolchildren, according to a study. Lifestyle behaviours show a lower effect as compared with prior BMI, but children with a healthier lifestyle have a reduced risk of overweight and obesity at follow-up.
Use of electronic vapour products (EVP), or vaping, has been associated with an increased likelihood of engaging in sexual and substance-use risk behaviours among US teenagers, according to data from the 2017 National Youth Risk Behaviour Survey presented at the Paediatric Academic Societies (PAS) 2019 Meeting.
Parenteral antibiotic therapy duration for bacteraemic urinary tract infection (UTI) in young infants may be safely shortened, according to a recent study showing that recurrence and readmission or emergency department revisitation rates are comparable between a ≤7-day and a longer therapy course.
