1, rubella is a common clinical infectious disease: in fact, rubella has nothing to do with wind and is caused by the rubella virus. As a contagious disease, the disease is easy to prevalent in winter and spring, and most often seen in older children or young people, rubella patients are the only source of infection for the disease. The virus is spread through the air and droplets. About 30% of healthy people who come into contact with the rubella virus become ill, and after recovering from the disease they gain immunity and rarely reoccur. The disease develops about 2 to 3 weeks after a person is infected with rubella virus. Patients may show symptoms of flu such as low fever, headache, lethargy, sore throat, etc. before the rash appears, which is short and mild and disappears after the rash develops. The rash appears as a light red rash or papule, which can be slightly itchy, sparse vegetables walk all over the body, often starting on the face, spreading rapidly to the neck, trunk, upper limbs and finally to the lower limbs within 24 hours, fading in about 2 days while starting, leaving no trace or slight flaking after fading. Patients may have swollen lymph nodes behind the occiput, behind the neck, and behind the ears with pressure pain 1 to 2 days before the rash appears. 2, rubella is a self-limiting disease: after getting rubella, generally do not need special treatment. Like the treatment of general viral colds, bed rest, drink more water, pay attention to a light, easy-to-digest diet. Oral antiviral drugs such as acyclovir and ribavirin can be taken. Patients who are able to do so can be treated with Chinese herbal medicine for better results. Other symptomatic treatments can be given to reduce fever and cough. Rubella should be isolated in time to prevent transmission to others. The infectious period is short, and isolation for 5 days from the appearance of the rash is sufficient. Of course, rubella is not something to be taken lightly. Occasionally, joint, otitis media, bronchitis, and even myocarditis and encephalitis can occur if rest and treatment are not provided in time. It is especially worth mentioning that rubella can cause miscarriage, stillbirth, premature birth or fetal malformation in pregnant women in the fourth month of pregnancy. The incidence of fetal malformations is about 15% to 20% if the child is infected with rubella in the first 3 months of pregnancy. Common malformations include congenital cataracts, deafness, missing teeth, small eye deformities, congenital heart disease, glaucoma, etc. Therefore, children should be vaccinated against rubella in early childhood to enhance their immunity to the rubella virus. It is important that women with early pregnancy avoid public places and contact with rubella patients.
