Specific type of URI
➢ Herpangina:coxsackie-viruses group A. summer /fall.High fever, sore throat，
1-4mm vesicles /ulcers on anterior tonsillar pillars, softpalate,uvula,tonsils pharyngeal wall. ➢ Pharyngoconjunctival fever :type 3,7 adenovirus, spring /summer. High fever, sore throat，pharyngitis, conjunctivitis, cervical lymphadenopathy.
Pathophysiology of thhe common cold
sore throat
