Acute rash in toddlers is caused by pathogenic microorganisms such as human herpesvirus type 6, human herpesvirus type 7, and enteroviruses, and can also be transmitted from person to person. It is a common rash disease in children under 2 years of age. Clinical studies have shown that it is mainly due to infection by human herpesvirus 6, followed by human herpesvirus 7, and enteroviruses such as coxsackievirus A, coxsackievirus B, echovirus, or pathogenic microorganisms such as adenoviruses and parainfluenza viruses. In addition to this, Eczema can be spread from person to person through contact with respiratory secretions or saliva. Typical symptoms of infantile rash are high fever, often above 39℃, which usually lasts for 3~5 days, followed by a skin rash that fades when pressed, and sometimes may be accompanied by irritability, diarrhea, and loss of appetite. Acute infantile rash is self-limiting and most children recover on their own, but if symptoms are severe, it is necessary to go to the hospital in a timely manner.
