Recently, herpes pharyngitis, chickenpox and other infectious diseases are prevalent, please pay attention to the family. Herpes pharyngitis is a viral infection that causes high fever in children, herpes in the pharynx and pain in the throat when it breaks down. Children show signs of not eating or not wanting to eat, being hungry but not able to eat, and crying a lot. The main treatment is symptomatic treatment, attention to care and balance of water and electrolytes. Chinese medicine has advantages in antiviral. Children with fever should not be covered (dressed thickly) and should be undressed to dissipate heat, otherwise the child’s temperature will not drop and even convulsions will occur; children with unremitting fever, poor mental response and poor nourishment, with one of the above phenomena, should see a doctor promptly. Herpes pharyngitis is very contagious and should be isolated. The saliva, herpes fluid, and stool of children and asymptomatic carriers contain more virus, which can contaminate hands, towels, cups, toys, and utensils, and can be contracted orally through daily contact. The virus is also contained in the oral secretions of the child, so coughing and sneezing can also cause transmission. Herpes pharyngitis is difficult to prevent, but there are still things we can do: wash your baby’s hands regularly, eat cooked food, and drink clean water, while ventilating your home, drying bedding, disinfecting toys, and avoiding public places as much as possible. And then there’s drinking more water.
