Is infantile rash contagious? Childhood rash is a common disease in pediatrics, mostly with a sudden onset. After two or three days of recurrent high fever, the body will develop large areas of red rashes. If parents or other family members carry human herpesvirus 6 or have close contact with other children with infantile rashes, due to the lack of immunity in the baby's body, it is entirely possible to be infected.
Causes of pediatric rash
1. Human herpesvirus 6 infection
The pathogen causing infantile rash is human herpesvirus 6. Due to the immune response of the human body to this virus infection, there is rarely a recurrence of infection. Therefore, the transmission of the virus is not only in babies who have already been infected, but more commonly in healthy carriers among parents and family members, who can be transmitted through respiratory droplets. The fetus can obtain antibodies from the mother through the placenta, with a positive rate of 25% at 4 months after birth, 76% at 11 months, 90% at 5 years old, and 98% at 17 years old. Childhood rash is more common in babies aged 6-18 months and less common after the age of 3. It is more common in the spring and autumn rainy seasons, and there is no gender difference.
2. Baby's resistance is low
Babies under 1 year old have incomplete development and poor ability to resist diseases. Especially for babies after 6 months, the levels of anti infective substances such as antibodies and nutrients such as iron from the mother gradually decrease, and the baby's ability to synthesize antibodies on their own is not yet complete. Therefore, the baby's ability to resist infectious diseases gradually declines, and is prone to various infectious diseases, especially colds and fever.
Is infantile rash contagious
Due to the incubation period of infantile rash being 1 to 2 weeks, close observation should be conducted during this period. If high fever occurs, immediate measures should be taken to temporarily isolate to prevent further transmission. If the child is still safe and sound after 2 weeks, it means that they have not been infected with the virus causing infantile rash. The key to preventing infantile rashes is to avoid contact with children who suffer from infantile rashes. At the same time, it is necessary to promote and encourage children to increase their exercise and improve their immunity in order to fundamentally prevent problems before they occur.
