Rubella is an acute respiratory infection caused by the rubella virus, which is prevalent in winter and spring. The secretions from the patient’s respiratory tract contain a large amount of virus. Patients are infected by breathing, coughing, sneezing and expelling the virus into the air. The clinical manifestations are characterized by varying degrees of fever and a generalized rash, often accompanied by swollen lymph nodes behind the ears and in the occipital region. The rash usually appears 1-2 days after the onset of fever, initially on the cheeks, and rapidly spreads to the trunk and extremities within 1 day, but the palms of the hands and soles of the feet are often free of rash. The rash is a light red or red papule that subsides in 2-3 days. The spleen and superficial lymph nodes are enlarged, especially behind the ear, occipital area, and behind the neck. When the rash recedes, the systemic symptoms also gradually subside, and the enlarged lymph nodes take several weeks to fully return to normal.
