Knowra Rubella Rubella Rubella is a contagious viral infection that usually causes a mild rash and fever. Infection during pregnancy can cause miscarriage, fetal death, or congenital rubella syndrome.
Rubella virus : An enveloped RNA virus in the Matonaviridae family that causes rubella. This virus is the infectious agent behind rubella.
MMR vaccine : A vaccine that protects against measles, mumps, and rubella. Its rubella component prevents infection and congenital rubella syndrome.
Congenital cataract : Clouding of the eye’s lens present at birth or developing in early childhood. It is a classic eye defect associated with congenital rubella syndrome.
Measles : A highly contagious viral disease that commonly causes fever, cough, conjunctivitis, and a widespread rash. Measles often causes a more severe illness and is caused by a different virus.
Respiratory droplet transmission : The spread of infectious particles released into the air during breathing, speaking, coughing, or sneezing. Rubella commonly spreads through droplets from an infected person’s respiratory tract.
Rubella serology : Blood testing for rubella-specific antibodies to assess immunity or recent infection. Antibody testing helps determine whether a pregnant person is immune or recently infected.
Congenital heart disease : A structural abnormality of the heart or major blood vessels present at birth. Rubella infection early in pregnancy can cause defects such as patent ductus arteriosus.
Roseola : A common childhood illness, usually caused by human herpesvirus 6, featuring high fever followed by a rash. Its rash can resemble rubella, but it usually appears as fever resolves.
Viremia : The presence of viruses in the bloodstream. After entering the body, rubella virus can circulate in blood and reach the placenta.
Rubella IgM : An antibody class whose detection can indicate recent rubella infection, though false positives occur. This test can support diagnosis when acute rubella is suspected.
