Rubella is an infection caused by a virus.
Some people call it German measles. It is often a mild sickness. Half of the people who get it do not even know.
Most people see a pink or light red rash. This rash starts on the face. Then it spreads to the rest of the body. It may last for three days. The rash can be itchy. Other signs include a fever or a sore throat. Adults may also feel pain in their joints.
Rubella spreads through the air. You can catch it from a cough.
It is very dangerous for pregnant women. The virus can pass to a baby. This can cause congenital rubella syndrome, or CRS. Children with CRS may have problems with their eyes, ears, or heart.
We can prevent rubella with a vaccine. A single shot is more than 95% effective. It is often part of the MMR vaccine. This shot protects against measles, mumps, and rubella. Vaccination has helped many places become free of the disease.
Rubella is a sickness caused by a tiny germ called a virus.
People often call it German measles or three-day measles. For many people, the sickness is very mild. In fact, half of the people who catch it do not even know they are sick. The name rubella comes from a Latin word meaning "little red." This describes the pink or light red rash that many people get.
This disease is important to study because it can be very serious for some.
The virus usually spreads through the air when an infected person coughs.
Once a person catches it, they can spread the virus to others. They are contagious for one week before the rash appears. They are also contagious for about one week after the rash shows up. The virus travels through the body and can be found in the blood. It can also be found in a person's throat or urine. Doctors can use tests to see if someone has the virus or has immunity.
Doctors first noticed this disease a long time ago. A German doctor named Friedrich Hoffmann described it in 1740. Later, in 1814, George de Maton said it was its own special disease. He said it was different from scarlet fever and regular measles. This is why people sometimes call it German measles. Because it was first studied by German doctors, it was also called Rötheln in Germany. Learning about these early doctors helps us see how we understood the germ.
Rubella can be very dangerous for babies during pregnancy. If a mother gets the virus, it can pass to the baby. This can cause a serious condition called congenital rubella syndrome, or CRS.
About 100,000 cases of CRS happen every year around the world. Babies with CRS might have problems with their eyes, like cataracts. They might also have trouble hearing or have heart problems. These issues are most common if the mother is infected during her first three months of pregnancy.
We can prevent rubella using a vaccine. A single dose of the vaccine is more than 95% effective. Many people get it as part of the MMR vaccine. This shot protects against measles, mumps, and rubella all at once. Vaccination has helped many places get rid of the virus. For example, the World Health Organization said the Americas were free of rubella in 2015. Australia was also declared rubella-free in October 2018. Vaccines are a powerful way to keep people healthy.
Rubella is a viral infection that humans can catch.
It is often called German measles or three-day measles. For many people, the sickness is very mild. In fact, half of the people who catch it do not even know they are infected. The name rubella comes from a Latin word meaning "little red." This refers to the pink or light red rash that many people develop. While it is often a minor illness, it is very important to understand. This is because the virus can cause severe harm to unborn babies.
The disease is caused by the rubella virus. This virus belongs to the genus Rubivirus and the family Matonaviridae.
It is an enveloped virus with a single-stranded RNA genome. The virus spreads through the respiratory route. This means it travels through the air when an infected person coughs. Once inside, the virus replicates in the nasopharynx and the lymph nodes. It can be found in the blood five to seven days after infection. From the blood, it spreads throughout the entire body. A person is contagious for about one week before the rash appears. They remain contagious for about one week after the rash shows up.
Symptoms of rubella can vary depending on the person's age. In children, the illness usually lasts about two days. The main sign is a rash that starts on the face. This rash then spreads to the trunk and the limbs. The rash is typically pink or light red and may be itchy. It usually fades after three days without leaving scars. Other symptoms in children include a low fever and swollen glands. In older children and adults, the symptoms can be more diverse. Adults may experience aching joints, especially young females. They might also have a sore throat, headache, or a fever. Some people develop Forchheimer spots, which are small red bumps on the soft palate. These spots appear in about 20% of cases.
One of the most serious parts of rubella involves pregnancy. The virus has teratogenic properties, which means it can interfere with a baby's development. If a woman is infected, the virus can cross the placenta. This can lead to congenital rubella syndrome, or CRS.
The risk of major defects is highest during the first trimester. Between 80% and 90% of mothers infected in this period face a miscarriage or a stillborn baby. If the baby survives, they may be born with CRS. This syndrome can cause deafness, blindness from cataracts, or heart disorders.
Babies with CRS may also have anemia or hepatitis. About 100,000 cases of CRS occur globally every year.
Doctors have been studying rubella for a long time. Friedrich Hoffmann, a German physician, gave the first clinical description in 1740. Later, in 1814, George de Maton suggested it was a unique disease. He argued it was different from scarlet fever and regular measles. This is why it earned the name "German measles." Because it was studied by German doctors, it was also called Rötheln. These early discoveries helped scientists understand how to identify the virus. Understanding the history of the disease has helped us develop better ways to fight it.
We can prevent rubella using a vaccine. A single dose of the vaccine is more than 95% effective. Most people receive it as part of the MMR vaccine. This combination protects against measles, mumps, and rubella. Vaccination has changed how much rubella affects the world. In the United States, the CDC announced the elimination of rubella in 2004. The World Health Organization declared the Americas free of rubella in 2015. Australia was also declared rubella-free in October 2018.
High vaccination rates create herd immunity, which stops the virus from spreading.
There is currently no specific treatment for rubella. Doctors instead manage the symptoms to make the person more comfortable. For newborn babies with CRS, doctors focus on treating complications. Surgery can sometimes correct heart defects or cataracts. It is important to test women of childbearing age for immunity. If a woman is not immune, she can be vaccinated. However, the MMR vaccine cannot be given during pregnancy because it contains a live virus. Instead, women should be vaccinated as soon as possible after giving birth. This helps keep both mothers and babies safe from the virus.
