Children’s skin is delicate and easily stimulated by foreign objects to induce an immune response to a rash. The following six rashes are common in young children because of their color, shape, distribution, and the different performance of the body before and after the rash: a. Emergency rash is a common rash disease in infants and young children, mostly caused by viral infections, with an incubation period of 8 to 14 days, mostly seen in infants within the age of one year, with more onset in winter and spring. It is characterized by a sudden onset of high fever (39-40℃), which lasts for 3-5 days and then subsides, with the appearance of rose-colored macules surrounded by a red halo, similar to rubella, measles or scarlet fever. Rubella is an acute infectious disease transmitted by respiratory droplets, which is common in childhood and caused by rubella virus. It mostly develops in winter and spring and can be prevalent in groups. The general incubation period is 10 to 21 days. The clinical symptoms of rubella are very similar to measles, but lighter than measles. They include cough, runny nose, sneezing, sore throat, loss of appetite, and often swollen lymph nodes behind the ears and occiput. Chickenpox is an acute infectious disease caused by the initial infection of varicella zoster virus. It occurs mainly in infants and young children and is characterized by fever and the appearance of circumscribed red papules, herpes and scabs in groups. The initial infection is chickenpox, and re-infection may result in herpes zoster. It is seen in all ages from 6 months of age. The onset is more common in winter and spring. The incubation period is 1 to 2 days. Measles is a common acute respiratory infection in infants and young children and is highly contagious. The main symptoms are fever, upper respiratory tract infection, conjunctivitis, etc. It is characterized by the appearance of red papules on the skin and mucosal spots of measles on the cheek mucosa. It is mainly transmitted through respiratory droplets of children with measles or through a third party as a vector, with the most frequent incidence in late spring. The incubation period is 6 to 18 days. V. Papular rash Papular rash is also called “sandy rash”. This disease mainly occurs in the summer, mostly in infants and children. Due to the hot weather, children sweat, which can easily lead to skin inflammation, forming a rash. It occurs on the wrists and backs of children’s hands, and in some cases on the forearms, thighs and buttocks. Six, hand, foot and mouth disease Hand, foot and mouth disease can have an onset throughout the year, often occurring in March to November, June to August is the peak, this disease spreads very quickly, spreads very widely, the onset of age can range from 4 months of age infants to 30 years of age adults, but the highest incidence of infants and children under the age of 3. Most of the several types of rashes that plague babies are due to poor function of the baby’s internal organs and a decrease in immune function related to endotoxin removal. When fever is present, you can drink more water, take antiviral drugs including antipyretic drugs, and adjust your baby’s diet to take care of the spleen and stomach. If the symptoms are significant and accompanied by fever, you should not be paralyzed, but pay great attention to it and take your baby to the hospital in time.
