Herpes pharyngitis is contagious and very contagious, usually spreading easily in kindergartens or schools, and in the spring and fall, children between the ages of one and seven are susceptible to herpes pharyngitis. Usually herpes pharyngitis causes blisters and ulcers in the roof of the body’s mouth and the back of the throat. The disease is very painful and patients also suffer from complications such as pain, sudden fever, sore throat, loss of appetite, difficulty swallowing, drooling, and neck pain. Herpes pharyngitis is usually transmitted through the respiratory tract, mouth, and intimate contact, and is very contagious and should be isolated and treated as soon as it is detected. Herpes pharyngitis usually occurs due to inadequate barrier function of the respiratory tract; softness of the respiratory mucosa; and inadequate secretion of immune substances against bacteria and viruses from the respiratory tract. Treatment of herpes pharyngitis is usually pain relief with ibuprofen and acetaminophen. Antibiotics are usually not used because herpes pharyngitis is usually caused by a virus, yet antibiotics are not effective in treating the virus.
