Rubella is contagious, and patients are the only source of rubella infection, including those with subclinical or cryptic infection, whose actual number is higher than that of those with the disease, making them an important source of infection that is easily overlooked. The infectious period is 5 to 7 days before and 3 to 5 days after the onset of the disease, with the day of onset and the day before being the most contagious. The virus can be isolated from the patient’s oral, nasal and pharyngeal secretions, as well as from blood and urine. Generally, rubella in children and adults is mainly transmitted by droplets through the respiratory tract, and can also be transmitted by contact between people in close contact. Newborns infected in the fetus, especially the pharynx can discharge the virus for weeks, months or even more than a year, so through contaminated bottles, nipples, clothes and diapers and direct contact with infected medical and family members lacking antibodies, or cause transmission in the infant room. Infection of the fetus can cause miscarriage, stillbirth, premature birth or congenital rubella with a variety of congenital malformations.
