Rubella is also known as "German Measles" and is caused by rubella virus. It can be transmitted by contact with secretions from nose and throat of infected persons through droplet spread or direct contact with patients. This is a highly infectious disease and the patient can pass the disease to other persons from 1 week before to 1 week after onset of rash.
People usually present with a diffuse rash, fever, headache, malaise, enlargement of lymph nodes, upper respiratory symptoms and conjunctivitis. The rash usually lasts for about 3 days, but some patients may not have rash at all. Arthralgia or arthritis occurs more commonly in adult women with rubella. Rubella infection can also cause anomalies in the developing foetus. Congenital rubella syndrome, characterised by deafness, eye lesions, heart malformations and mental retardation, is likely to occur in infants born to women who got infected during the first 3 months of pregnancy.
