What is the main route of rubella transmission? What are the epidemiological characteristics?

Rubella is a virus infection, and the pathogen is rubella virus, which can be spread by droplets. Children are most susceptible to rubella virus when they are 1~5 years old. Contact with contaminated nipples and bottles may lead to infection. If pregnant women are infected with rubella virus, it will cause congenital malformation of fetal abdomen, and the probability of congenital heart disease and deafness will be greatly increased after birth. For adults, rubella is a very troublesome and painful thing, because it is difficult to cure at one time.

If you have rubella, you should pay special attention to causing complications. Although most rubella patients will not cause complications, there are still about 10% people who will have complications. Complications mainly include pharyngolaryngitis, otitis media, pneumonia, bronchitis, hepatitis, thrombocytopenic purpura, hemolytic anemia, acute nephritis, pancreatitis, gastrointestinal bleeding, myocarditis, encephalitis and arthritis. For rubella, take the initiative to prevent it. The main means is vaccination. The vaccine mainly adopts live attenuated rubella vaccine, which can produce serum rubella antibody after inoculation, which can effectively prevent rubella virus infection, and the protection period is relatively long, at least up to 15~20 years.

There are three kinds of vaccines, including univalent, rubella-measles vaccine and rubella-measles-mumps triple vaccine. As the name implies, different prices have different functions. If you are infected with rubella, you should see a doctor. If you are seriously ill, you need to stay in bed and eat liquid or semi-liquid food. Cough, high fever and headache all need symptomatic treatment. If complications are caused, special treatment is needed. For example, arthritis is the most common complication of rubella patients, and aspirin or Yingtaiqing is needed to relieve the symptoms. If you have symptoms of thrombocytopenic purpura, you can inject immunoglobulin intravenously. When healthy people are infected with rubella virus, they only need symptomatic treatment, such as wiping their foreheads and armpits with a towel when they have a high fever, and controlling their body temperature within a certain range. After the rash appears and subsides, the infection period can be successfully passed.

During the eruption, patients should be careful not to go out, keep indoor ventilation, have a light diet and eat some high-protein diet properly. Generally, antiviral treatment is not needed, and heat-clearing and antidote can be used appropriately. However, patients with basic diseases should pay attention to prevent the induction or aggravation of basic diseases. For the prevention of rubella, we should actively follow the procedures and scientifically complete rubella vaccination, which is divided into two parts, the first part is the primary immunization, and the second part is the strengthening. The first vaccination was when the child was eight months old, and the second vaccination was between 12 and 14 years old. Most vaccinated children have no adverse reactions, and about 10% will have temporary fever, low fever or even a slight rash, which will soon disappear. Adults who are not vaccinated against rubella can also be vaccinated against rubella, especially women who are preparing to get pregnant.
