Pharyngitis is an acute infectious disease of the pharynx caused mainly by intestinal viral infections. The early symptoms of the disease are pain in the throat, painful swallowing, and even difficulty in swallowing. In some cases of serious infection, there is also a high fever. The main treatment for this disease is the symptomatic use of antiviral drugs, and it is generally recommended to choose acyclovir or ganciclovir infusion therapy. If the body temperature exceeds 38.5℃, use antipyretic drugs as appropriate. Generally speaking, children are recommended to use antipyretic suppositories, which have relatively fewer side effects, and then drink more water to promote excretion, and do ultrasonic nebulizer inhalation therapy if available. The disease is somewhat contagious in the early stages of its onset, so it is important to pay attention to isolation while treating it.
