Herpes pharyngitis, clinically known as herpes pharyngitis, is an acute inflammatory disease that occurs in the pharynx, cheeks and neck of the body, usually in the fall and spring, and often in children between the ages of one and seven, and usually takes about seven days to heal on its own. Herpes pharyngitis can recur because the disease is usually caused by a viral infection in the body, and although antibodies are formed in the body after healing and the body becomes immune to the virus, herpes pharyngitis is usually not caused by one virus, and if the child is infected with another virus and does not have antibodies, he or she can still have herpes pharyngitis. Herpes pharyngitis is one of the infectious diseases and is very contagious, usually spread through the respiratory tract, mouth, and close contact. If a child is found to have herpes pharyngitis in the nursery, it is important to isolate the child in a timely manner to prevent transmission of the virus to other children; it is also important to disinfect the room regularly so that the bacteria and virus do not multiply too quickly and invade the child’s respiratory tract, leading to illness. As a child grows and develops, the immunity and resistance of the body improves year by year, so the probability of developing herpes pharyngitis becomes smaller and smaller. Encouraging patients to do more physical exercise in their daily life can improve the body’s resistance.
