How to recognize and prevent rubella (german measles )
Look for a pinkish skin rash.
The signs and symptoms of a rubella infection tend to be very mild and difficult to notice. However, its most distinctive characteristic is a fine, pink-colored rash that begins on the face and quickly spreads to the neck, trunk and then the limbs.
The rash typically lasts for between 1-3 days, then disappears in the same sequence that it appeared (face-] trunk-] limbs). The distinctive skin rash only occurs in 50-80% of cases of rubella.
