If you do not have a history of allergy
, this could be an infection caused by a virus or
bacteria. In particular, Rubella or
German measles is an infection that primarily affects the skin and lymph nodes. It is caused by the rubella virus, which is usually transmitted by droplets from the nose or throat that others breathe in. Rubella infection may begin with 1 or 2 days of mild fever and swollen, tender lymph nodes, usually in the back of the neck or behind the ears.
