summary

It takes a long time for people to get sick and be found, but we can't find it in time. It's just like the time when the appearance of rubella will hide for a while. People should have no feeling between them, but it will be more obvious when it appears. So, the latent symptoms of rubella?? Now let's answer it.

Latent symptoms of rubella?

Rubella is caused by rubella virus. The virus exists in the saliva and blood of the sick child 5-7 days before the eruption, but it is not easy to find 2 days after the eruption. The incubation period of rubella virus was 10-20 days. Rubella virus is weak in vitro, but as infectious as measles. It is usually transmitted by coughing, talking or sneezing.

This disease is more common in children aged 1-5 years old. Once they get sick, they can be immunized for life and seldom get sick again. It takes 14-21 days for rubella to appear from infection to symptoms. In the first 1-2 days of the disease, the symptoms are very mild, including low or moderate fever, mild cough, fatigue, bad appetite, sore throat, red eyes and other mild upper respiratory symptoms. The oral mucosa of the patient was smooth without hyperemia and mucosal spots, and the lymph nodes behind the ear and occipital region were swollen with mild tenderness.

The rash usually appears after 1-2 days of fever. The rash starts from the face and neck and spreads to the whole body within 24 hours. At first, the rash is a sparse red macular papule. Later, the rash on the face and limbs can fuse, similar to measles.

matters needing attention

1. Immunization is an effective way to prevent rubella. Rubella vaccine is a live attenuated virus strain, which has been used for more than 40 years. More than 95% long-term immunity could be obtained by single dose inoculation, which was close to that induced by natural infection. 2. Rubella vaccine can be monovalent (only for one pathogen) or combined with other vaccines, such as measles (MR), measles and mumps (MMR) or measles, mumps and varicella (mmrv).
