Rubella, also known as German measles or three-day measles, is a viral infection caused by the rubella virus. It is generally mild, with many cases going unnoticed. However, it can have severe consequences, particularly when contracted during pregnancy.

Rubella symptoms are similar to those of the flu. The primary symptom is a rash that starts on the face and spreads to the trunk and limbs, typically fading after three days. This rash is less intensely red than that of measles and may be itchy. Other common symptoms include low-grade fever, swollen lymph nodes, joint pains, headache, and conjunctivitis. In children, the rash usually clears as it spreads, and the fever rarely exceeds 38°C (100.4°F). Adults, especially females, may experience joint pain and arthritis. Severe complications can include encephalitis, low platelet count, and ear infections.

Congenital Rubella Syndrome (CRS)

Rubella infection during early pregnancy can lead to congenital rubella syndrome (CRS), characterised by severe birth defects such as cataracts, deafness, heart defects, and brain damage. The risk of major defects is highest during the first trimester, making vaccination important for women of childbearing age.

Rubella is caused by the rubella virus, a member of the genus Rubivirus from the family Matonaviridae. It is transmitted through respiratory droplets and replicates in the nasopharynx and lymph nodes. The virus appears in the blood 5-7 days post-infection and can cross the placenta, affecting the developing foetus.


Diagnosis of rubella is confirmed by detecting rubella virus-specific IgM antibodies in the blood, throat, or urine. These antibodies can persist for over a year, so a positive test result must be interpreted with caution. The presence of antibodies alongside the characteristic rash helps confirm the diagnosis.


Rubella is preventable through vaccination. The rubella vaccine, often administered as part of the MMR (measles, mumps, rubella) vaccine, is over 95% effective with a single dose. The WHO recommends the first dose at 12-18 months and a second dose at 36 months. Pregnant women should not receive the vaccine due to the live virus it contains. Instead, they should be vaccinated postpartum if they are susceptible.


There is no specific treatment for rubella. Management focuses on alleviating symptoms, such as using antipyretics for fever and analgesics for joint pain. For newborns with CRS, treatment is directed at managing complications, including surgical correction of heart defects and cataracts.


Rubella infection in children and adults is generally mild and self-limiting, often asymptomatic. However, the prognosis for children born with CRS is poor due to the potential for severe and multiple congenital defects.


Rubella occurs worldwide, with a tendency to peak in the spring in temperate climates. Before the introduction of the vaccine in 1969, widespread outbreaks occurred every few years. The disease has become rare in countries with high vaccination rates, but it remains a significant health issue in regions with lower vaccination coverage. The Americas have been declared free of endemic rubella transmission since 2015, but vigilance is necessary to prevent reintroduction from other areas.

Understanding rubella, its prevention, and its potential complications is essential for healthcare professionals, including dentists, to ensure comprehensive patient care.
