Overview
Rubella is a common childhood infection usually with minimal systemic upset although transient arthropathy may occur in adults. Serious complications are very rare. If it were not for the effects of transplacental infection on the developing foetus, rubella is a relatively trivial infection.
Causes
The disease is caused by Rubella virus, a togavirus that is enveloped and has a single-stranded RNA genome.[1] The virus is transmitted by the respiratory route and replicates in the nasopharynx and lymph nodes. The virus is found in the blood 5 to 7 days after infection and spreads throughout the body. It is capable of crossing the placenta and infecting the fetus where it stops cells from developing or destroys them.[2]
Differentiating Rubella from other Diseases
There are dermatological conditions that are similar in appearance to Rubella. These diseases need to be accounted for when diagnosing Rubella.
Screening
Rubella on its own is not a very life threatening disease. The biggest problem with Rubella is called congenital rubella syndrome. Since it is possible for a mother with Rubella to transmit it to her child, routine screening needs to be done. It is important to screen susceptible women, who may become pregnant, to help avoid the possibility of congenital rubella syndrome.
Treatment
Medical Therapy
There is currently no antiviral therapy for rubella. Most of the support during rubella infection is supportive and includes treatments such as painkillers.
