Rubella spreads all over the world and is an endemic disease in temperate regions. The peak incidence is from spring to early summer. Rubella virus can spread through the respiratory tract, with nasopharyngeal secretions as the main source of infection. The virus does not have a strong ability to infect through contact. Occasionally, it may not form an infection. Its incubation period is 10 to 21 days. Afterwards, it shows clinical symptoms such as cough, runny nose, throat pain, headache, fever, and poor appetite. A rash may appear on the face first, and all over the body within a month.

Medical network collection, the severity of infection mainly depends on which infection occurred in pregnancy period. If infected within 8 weeks of pregnancy, the spontaneous abortion rate reaches 20%. The 12th week can almost certainly lead to fetal infection and serious sequelae. Others can also cause heart and eye defects, retinopathy, hearing loss, diabetes and other endocrine Diseases, neurological deafness, glaucoma, etc. Infection of rubella virus in the early pregnancy of the mother can almost cause extensive and continuous multiple organ infection of the fetus, leading to stillbirth.
