Introduction
Introduction to baby rose rash Exanthema Subitum, also known as baby rose rash, is an acute benign rose-like rash in infants and young children characterized by hot rash. basic knowledge Sickness ratio: 0.1% Susceptible people: mostly occur in children under 2 years old Mode of infection: non-infectious Complications: Hepatitis Pneumonia Orchitis Acute laryngitis Bronchial pneumonia Diarrhea Pediatric convulsions
Cause
Baby rose rash
The study found that the majority of children's acute rash is caused by human herpesvirus 6 (HHV26) infection, a small part is caused by HHV27 infection; some people think that it is caused by Coxsackie virus B5, but there is no clear evidence, and some of the causes are unknown. .
Prevention
Baby rose rash prevention
The key to prevention is not to contact children with children with acute rash. At the same time, children should be encouraged and encouraged to increase their exercise and improve their immunity in order to prevent them from happening.
Complication
Baby rose rash complications Complications Hepatitis pneumonia orchitis acute laryngitis bronchopneumonia diarrhea children with convulsions
Previously, healthy children had few complications, but children with low immune function may have complications such as hepatitis or pneumonia. However, there have been reports in recent years that children with acute rashes in children have been seen at home and abroad. Accompanied by acute orchitis, acute laryngitis, bronchial pneumonia, diarrhea, benign intracranial pressure, convulsions.

Examine
Baby rose rash check
1. Blood routine examination: see a decrease in the total number of white blood cells, accompanied by neutropenia. It is also possible to subsequently increase the total number of white blood cells.
2. Virus isolation: Virus isolation is a diagnostic method for HHV-6 and 7 infections.
3. Detection of viral antigens: Viral antigen detection is suitable for early diagnosis, but viremia is maintained for a short time, and it is difficult to take specimens in time.
4. Determination of viral antibodies: Determination of HHV-6, 7 IgG, IgM antibodies by ELISA and indirect immunofluorescence is currently the most common and simple method.
5. Viral nucleic acid detection: HHV-6, 7 DNA can be detected by nucleic acid hybridization method and PCR method. Since both HHV-6 and 7 have latent infections, the DNA of the virus is sometimes detected, and it is not confirmed that it is in a latent state or an activated state.
Diagnosis

diagnosis
The clinical symptoms of children with acute rash are typical and the diagnosis is easier. However, it is worth noting that the disease is mostly caused by sudden high fever, and the diagnosis can be confirmed when the rash is removed after 1 to 5 days. Although some children with soft sputum visible characteristic erythema (Nagayama's spots), it is still easy to be mistaken for acute upper respiratory tract infection, drug eruption, measles, rubella, pneumococcal sepsis and other diseases. Therefore, for some atypical cases, differential diagnosis should be done, medical history, allergy history and physical examination should be carefully asked, and serum measles and rubella IgM antibodies should be detected in time to avoid misdiagnosis and missed diagnosis. Therefore, if you encounter a baby with sudden high fever without obvious cause, you should consider the progenitor period of the child's acute rash.
Differential diagnosis
(1) Measles upper respiratory tract catarrhal symptoms, Koplik plaques in the oral mucosa at the beginning of the disease, rash and fever can exist at the same time.
(2) The rubella has fever for 6 to 24 hours before the rash, high fever and rash at the same time, and the lymph nodes are enlarged after the neck and the back of the pillow.
(3) The drug rash has a history of medication, and the peripheral blood lymphocytes are not high.
