Tonsillopharyngitis%20-%20acute Signs and Symptoms

• Tonsillopharyngitis is the acute infection of the pharynx, tonsils, or both
• Also called strep throat, acute tonsillitis, pharyngitis or adenotonsillitis
• One of the most common diseases seen in primary care

• 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
• The primary reservoir of group A streptococcus are the humans
• The disease is easily transmitted in the following places:
  • Schools
  • Day care centers
  • 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 or bacteria
