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.

Baby rose rash diagnosis and identification

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.
