- Rubella is an infectious disease caused by the rubella virus and is also commonly referred to as 'German measles'.
- Rubella can be transmitted through respiratory droplets from an infected person's cough or sneeze, and even asymptomatic individuals can spread the virus.
- After the rubella virus is transmitted via the respiratory tract, it causes infection and an immune response; if infection occurs during pregnancy, it can affect the fetus.
- Representative clinical manifestations include a rash that starts on the face and spreads to the body, low-grade fever, lymphadenopathy, and arthralgia.
- Most infections are mild, but infection during pregnancy is associated with the risk of miscarriage or congenital anomalies in the fetus, and the impact can vary greatly by individual.
- About half of infected individuals may be asymptomatic, and when symptoms do appear, fever, rash, lymphadenopathy, and arthralgia are the primary manifestations.
- Diagnosis is made by reviewing symptoms along with exposure history, travel history, and vaccination history, and confirming infection via serum antibody tests or molecular tests if necessary.
- Since rash and fever can also occur in other viral infections, it is difficult to definitively diagnose rubella based on clinical symptoms alone; if the patient is pregnant or there is a possibility of pregnancy, test results must be carefully interpreted with medical staff.
- The core of management involves contact control considering transmission risk, symptom relief, assessment of pregnancy-related risks, and infection prevention.
- No specific treatment to eliminate rubella itself has been established, and the measles, mumps, and rubella (MMR) vaccine is used for prevention.
