Rubella [rue-BELL-uh] is a mild but very contagious viral illness. Other names for rubella are German measles and three-day measles.
Rubella is dangerous because of its ability to harm unborn babies. Infection in a pregnant woman can result in :
People get rubella by breathing in droplets that get into the air when an infected person coughs, sneezes, or talks. Rubella can also spread by direct contact with fluids from the nose or throat of an infected person.
Rubella can be prevented by immunization.
Rubella is caused by the rubella virus.
Rubella is found worldwide.
People get rubella by breathing in droplets that get into the air when an infected person coughs, sneezes, or talks.
Rubella can also spread by direct contact with fluids from the nose or throat of an infected person.
After an incubation period of 14–21 days, German measles causes symptoms that are similar to the flu. the primary symptom of rubella virus infection is the appearance of a rash (exanthem) on the face which spreads to the trunk and limbs and usually fades after three days (that is why it is often referred to as three-day measles).
The facial rash usually clears as it spreads to other parts of the body. Other symptoms include low grade fever, swollen glands (post cervical lymphadenopathy), joint pains, headache and conjunctivitis.
The swollen glands or lymph nodes can persist for up to a week and the fever rarely rises above 38 oC (100.4 oF).
The rash of German measles is typically pink or light red. The rash causes itching and often lasts for about three days. The rash disappears after a few days with no staining or peeling of the skin. When the rash clears up, the patient may notice that his skin sheds in very small flakes wherever the rash covered it.
Forchheimer's sign occurs in 20% of cases, and is characterized by small, red papules on the area of the soft palate.
Rubella can affect anyone of any age and is generally a mild disease, rare in infants or those over the age of 40. The older the person is the more severe the symptoms are likely to be.
Up to one-third of older girls or women experience joint pain or arthritic type symptoms with rubella.
The virus is contracted through the respiratory tract and has an incubation period of 2 to 3 weeks. During this incubation period, the patient is contagious typically for about one week before he develops a rash and for about one week thereafter.
An infected person can spread the disease for as many as 5 days before the rash appears to 7 days after. Infectious children should not attend school or day care.
In most cases, symptoms appear within 16 to 18 days.
Diagnosis is by blood test or virus culture.
Anyone can get rubella, but unvaccinated, school-aged children are most at risk.
Rubella is not usually a serious disease in children, but it can be very serious if a pregnant woman becomes infected. When a woman gets rubella during pregnancy, especially during the first 3 months, the infection is likely to spread to the fetus and cause CONGENITAL RUBELLA SYNDROME (CRS).
Up to 20% of the infants born to mothers infected with rubella during the first trimester of pregnancy have CRS. CRS can result in miscarriage, stillbirth, and severe birth defects.
The most common birth defects are :
There is no treatment for rubella. The illness usually runs its course in a few days.
Since the rubella vaccine was introduced in 1969, cases of rubella and CRS in the United States have remained low. However, cases are reported in persons who were infected in countries that do not routinely provide rubella vaccination (imported rubella). Although CRS is preventable, up to 7 infants are born with CRS each year.
In unvaccinated populations, rubella is primarily a childhood disease. When children are well immunized, adolescent and adult infections become more evident. Since 1994, most rubella and CRS cases were associated with outbreaks among adults, and 75% of all rubella cases were among persons 15-44 years of age.
Rubella can be prevented by IMMUNIZATION.
As is the case with all immunizations, there are important exceptions and special circumstances. Health-care providers should have the most current information on recommendations about the rubella vaccine.
