Tonsillopharyngitis%20-%20acute Signs and Symptoms
Definition
- Tonsillopharyngitis is the acute infection of the pharynx, palatine tonsils, or both
- Also called strep throat, acute tonsillitis, pharyngitis or adenotonsillitis
- One of the most common diseases seen in primary care
Etiology
- Main cause of acute tonsillopharyngitis
- Double-stranded DNA viruses (human adenovirus, Epstein-Barr virus), single-stranded RNA viruses [influenza, para-influenza, rhinovirus, enteroviruses, Coxsackie virus, coronaviruses, respiratory syncytial virus (RSV), human meta-pneumo-virus], and retroviruses [human immunodeficiency virus (HIV)] are among the viral causes
- Responsible for about 5-15% of clinic consultations for acute sore throat in adults
- Most commonly caused by Gram-positive cocci known as S pyogenes
- This organism exhibits beta-hemolysis on blood agar plates
- Belongs to group A Lancefield classification system for beta-hemolytic strep infection
- Other bacterial causes include group C and G Streptococci, Haemophilus influenzae, Nocardia, Corynebacteria and Neisseria gonorrhoeae
- Spreads through person-to-person contact, usually through saliva or nasal secretions from an infected person
- Primary reservoir of group A Streptococcus are the humans
- Easily transmitted in the schools, day care centers, and military training facilities
- Transmission via food is rare and if transmission happens, it is most of the time due to improper handling of food
- Pets and the use of household items such as plates and toys cannot transmit the disease
