It is not a certainty that you will experience early childhood emergency rash.
It occurs up to 2 years of age, with 7 to 13 months of age being the peak age group for the onset of the disease, and is rare before 3 months of age and after 4 years of age, and is occasionally seen in older children, adolescents, and newborns. Although not every child will get Eczema, the incidence is still very high.
Human herpesvirus types 6 and 7 are the main pathogens for toddler rash. Different children have different resistance, different antibodies from the mother, and different abilities to fight off viral infections. Therefore, some children will not get infantile emergency rash, which means that the incidence of infantile emergency rash is not 100%.
For children with persistent high fever, it is important to make a good differential diagnosis so as not to delay the disease.
