what is the difference between measles and rubella
Measles, mumps, and rubella are viral diseases. All can be very serious. Measles starts as a fever, cough, runny nose, conjunctivitis (pinkeye), and a red, pinpoint rash that starts on the face and spreads to the rest of the body. If the virus infects the lungs, it can cause pneumonia.
Rubella is also known as German measles. It can cause a mild rash on the face, swelling of glands behind the ears, and in some cases, swelling of the small joints and low-grade fever. Most children recover quickly with no lasting effects. But if a pregnant woman gets rubella, it can be devastating.
