Rubella
Moderate
Rubella is a contagious viral infection that commonly causes a mild rash, fever, swollen lymph nodes, and other symptoms. It spreads mainly through respiratory droplets when an infected person coughs or sneezes. Rubella is particularly important during pregnancy because infection can seriously affect a developing baby. Rubella is often mild, and some infected people have few noticeable symptoms. When symptoms occur, they may include a low-grade fever, sore throat, headache, tiredness, and swollen lymph nodes followed by a fine rash that begins on the face and spreads downward. The illness usually resolves without serious complications in otherwise healthy people, but infection during pregnancy can result in congenital rubella syndrome and severe problems affecting the developing baby.

When to Seek Medical Attention
Rubella is usually a mild infection but is particularly important to assess during pregnancy because fetal infection can cause serious complications. Seek prompt medical advice for suspected infection during pregnancy or significant worsening symptoms. Emergency assessment is appropriate for severe breathing difficulty, neurological symptoms, fainting, or another acute medical problem.

Causes 1
Rubella is caused by the rubella virus. The virus spreads from person to person through respiratory droplets released when an infected individual coughs, sneezes, or talks. A person can spread the infection before and after the rash appears, making transmission possible even when symptoms are not obvious. The rubella virus enters through the respiratory tract and multiplies in the body before spreading through the bloodstream. Infected people can transmit the virus even when symptoms are mild. The virus can cross the placenta during pregnancy and infect the developing fetus, which accounts for the serious congenital complications associated with maternal infection.
Infection
Risk Factors
Risk factors include lack of vaccination, exposure to a person with rubella, and living or traveling in areas where rubella continues to circulate. Pregnant people who are not immune are at particular risk of complications if they become infected. The greatest concern is among people who are not immune and are exposed to circulating rubella virus. Lack of vaccination is the major preventable risk factor. International travel or residence in communities with incomplete vaccination coverage can increase the chance of exposure. Pregnancy substantially increases the potential consequences of infection.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Rubella is diagnosed using the medical history, symptoms, physical examination, and laboratory testing. Blood tests can detect rubella-specific antibodies, while molecular tests may detect viral genetic material. Testing is particularly important during pregnancy or when confirmation is needed for public health purposes. Because the symptoms can resemble other viral infections, laboratory confirmation is useful when rubella is suspected. Testing may include detection of rubella-specific IgM antibodies or changes in IgG antibodies over time. Molecular testing can also help confirm infection. Public health authorities may recommend testing in suspected outbreaks.
Prevention
Key Prevention Tips
Rubella can largely be prevented through vaccination
Maintaining recommended immunization and avoiding exposure to infected people help reduce transmission
People planning pregnancy should discuss immunity with a healthcare professional because vaccination is generally given before pregnancy rather than during pregnancy
Maintaining high vaccination coverage is the principal public-health method for preventing rubella
People should follow recommended immunization schedules and check immunity before pregnancy when appropriate
Anyone suspected of having rubella should follow public-health and infection-control advice to reduce exposure to susceptible people
Prevention Guidance
Rubella can largely be prevented through vaccination. Maintaining recommended immunization and avoiding exposure to infected people help reduce transmission. People planning pregnancy should discuss immunity with a healthcare professional because vaccination is generally given before pregnancy rather than during pregnancy. Maintaining high vaccination coverage is the principal public-health method for preventing rubella. People should follow recommended immunization schedules and check immunity before pregnancy when appropriate. Anyone suspected of having rubella should follow public-health and infection-control advice to reduce exposure to susceptible people.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
