摘要: Acute pharyngitis may be caused by a wide variety of microbial agents (Table 1). The relative importance each these varies greatly depending on number epidemiologic factors, including age the patient, season year, and geographic locale. Viruses Most cases acute are viral in etiology involve pharynx as well other portions respiratory tract manifestations common cold, influenza, or croup. Examples include rhinoviruses, coronaviruses, influenza A B, parainfluenza viruses. Certain infections causing sore throat exhibit clinical that rather distinctive. enteroviruses (herpangina due to Coxsackie A), Epstein-Barr virus (infectious mononucleosis), cytomegalovirus (cytomegalovirus adenovirus (pharyngoconjunctival fever, disease military recruits), herpes simplex (pharyngitis, gingivitis, stomatitis). In many instances, however, illnesses overlap so broadly with streptococcal clinically indistinguishable. Thus, virus, adenovirus, all cause exudative pharyngitis, cervical adenitis. Several studies have documented role primary herpesvirus type 1 infection college students.1-4 Herpesvirus 2 can occasionally similar illness consequence oral-genital sexual contact.5 Although anterior oral cavity (vesicular ulcerative gingivostomatitis) posterior pharynx, they do not routinely so. Only about one-fourth students culturally serologically proven studied Glezen et al,2 for example, had gingivostomatitis.
