Key Differences in Symptoms Causes Transmission and Prevention of Measles and Rubella
Paramyxoviruses, which cause the measles virus, is extremely contagious RNA viruses. Measles viruses can survive for up to two hours in the air. An outbreak may last as long as 10 days but the disease takes between 1 and 2 weeks to incubate. Contagiousness is greatest when the disease is in its early stages (prodromal stage). A person is contagious for a prolonged period. Ninety percent of people who are exposed to measles will develop the disease. When sick people cough or sneeze, droplets produced from their coughs or sneezes infect others. Check out the official website of Vedantu or download the app for an elaborate and easy explanation.
Symptoms
In severe cases, there is often a fever greater than 40°C
Cough
Conjunctivitis
Usually, conjunctivitis involves inflammation of the external membrane of the eye, resulting in red, watery eyes.
Those with photophobia experience physical sensitivity to sunlight.
Essentially, this is a rash that develops on the membranes that produce mucus.
The inside of the mouth can be inflamed by Koplik spots (small rashes).
It is a reddish area with small bumps called a maculopapular rash. These bumps appear on the head and spread to the limbs.
Rashes that are more severe can result in mild to severe bruises.
A Koplik spot appears in the mouth prior to a rash appearing. The rash appears approximately five days after the illness started. Within about a day, the rash appears on the face, and it spreads to the body, abdomen, and limbs.
The rash begins to fade about 5 days after the patient first appears.
Some people can suffer from severe measles, which results in brain swelling and even blindness. In some cases, complications such as pneumonia or encephalitis can lead to death from measles.
Vaccination against measles is possible. Immunity against the virus is provided by the MMR vaccine. The prevalence of measles has decreased significantly as a result of widespread vaccination.
What is Rubella?
A virus that causes rubella also has RNA as its nucleic acid. In the same way, that measles is spread through breathing secretions, coughing, and sneezing. A person infected may be contagious for up to a week before they show signs of illness. After showing signs of illness, they may remain contagious for about two weeks.
The German measles isn't nearly as contagious as measles, so it is also called German measles. Rubella sometimes causes illness without symptoms. Except for those with a compromised immune system, it is not a serious illness. It takes about two to three weeks for the disease to incubate.
Symptoms
This may be accompanied by a low fever (less than 38.3o C), general discomfort, conjunctivitis, and swollen lymph nodes. In some cases, people may experience pain in the joints.
The back of the throat becomes reddish in color and there are often painful, swollen lymph nodes in the neck.
The prodromal stage of rubella does not manifest any symptoms. Symptoms of rubella include fever and rash similar to those of measles.
Rubella is best prevented by the MMR vaccine. With vaccination programs, incidences of Rubella have decreased.
Difference between Measles and Rubella
Rubella and Measles are both caused by RNA viruses. The virus is transmitted by infected people's nasal droplets. The symptoms of both diseases are similar, but the rashes are slightly different. The MMR vaccine prevents both diseases.
Summary
Measles and rubella are both caused by an RNA virus which is transmitted through the respiratory droplets that sick people produce.
Measles is more severe than rubella and highly contagious.
Though both measles and rubella have similar symptoms such as rash, the fever between the two is slightly different.
Rash and symptoms of measles last longer than rubella.
Though measles does, Rubella has no prodromal period.
Rubella causes fever to small and does not last long. As in the case of measles, the pupils are also not sensitive to light.
Measles and rubella in a pregnant woman can both cause problems for the fetus.
A person with the MMR (mumps measles rubella) vaccine may be vaccinated against both of these diseases.
FAQs on Difference Between Measles and Rubella in Detail
1. What is the difference between measles and rubella?
The main difference between measles and rubella is that measles is a more severe viral disease causing high fever and respiratory symptoms, while rubella is usually milder but dangerous in pregnancy.
- Measles is caused by the Measles virus (genus Morbillivirus).
- Rubella is caused by the Rubella virus (genus Rubivirus).
- Measles causes high fever, cough, and a widespread rash.
- Rubella causes mild fever, rash, and swollen lymph nodes.
- Rubella can lead to congenital rubella syndrome (CRS) in unborn babies.
2. What causes measles and rubella?
Measles and rubella are caused by two different RNA viruses belonging to different genera.
- Measles is caused by the Measles virus, a single-stranded RNA virus of the Paramyxoviridae family.
- Rubella is caused by the Rubella virus, a single-stranded RNA virus of the Matonaviridae family.
- Both spread mainly through respiratory droplets from infected individuals.
3. How can you tell the difference between measles rash and rubella rash?
The measles rash is darker and more intense with severe symptoms, while the rubella rash is lighter and milder.
- Measles rash:
- Starts at the hairline and spreads downward.
- Associated with high fever and Koplik spots inside the mouth.
- Rubella rash:
- Also begins on the face but spreads faster and fades quickly.
- Usually accompanied by swollen lymph nodes behind the ears.
4. What are the main symptoms of measles?
The main symptoms of measles include high fever, cough, runny nose, red eyes, and a widespread skin rash.
- High fever (often above 39°C)
- Cough, coryza, and conjunctivitis (the 3 C’s)
- Koplik spots on the inner cheeks
- Red, blotchy rash spreading from face to body
5. What are the main symptoms of rubella?
The main symptoms of rubella are mild fever, rash, and swollen lymph nodes.
- Low-grade fever
- Pink or light red rash
- Swollen postauricular and occipital lymph nodes
- Mild joint pain, especially in adults
6. Why is rubella dangerous during pregnancy?
Rubella is dangerous during pregnancy because it can cause congenital rubella syndrome (CRS) in the developing fetus.
- The virus can cross the placenta.
- It may cause deafness, heart defects, and cataracts.
- Highest risk occurs during the first trimester.
7. How do measles and rubella spread?
Measles and rubella spread mainly through respiratory droplets from coughing and sneezing.
- Transmission occurs via airborne droplets.
- Close contact with infected individuals increases risk.
- Measles is highly contagious and can remain infectious in the air for up to two hours.
8. What is the MMR vaccine and how does it protect against measles and rubella?
The MMR vaccine is a combined vaccine that protects against measles, mumps, and rubella by stimulating immunity.
- Contains live attenuated (weakened) viruses.
- Triggers production of specific antibodies.
- Provides long-lasting immune memory.
9. Which disease is more severe: measles or rubella?
Measles is generally more severe than rubella due to its higher fever and risk of serious complications.
- Measles can cause pneumonia, encephalitis, and death.
- Rubella is usually mild in children and adults.
- However, rubella becomes severe when it affects a fetus.
10. Can a person get measles and rubella more than once?
A person usually develops lifelong immunity after recovering from measles or rubella infection.
- Natural infection produces long-lasting adaptive immunity.
- The MMR vaccine also provides strong, long-term protection.
- Reinfection is extremely rare in immunocompetent individuals.
