What is the Centor Criteria?
Used to estimate the probability that tonsillitis is due to bacterial infection and will benefit from antibiotics
Explain the Centor criteria
≥ 3 means 40-60 % probability of bacterial tonsillitis → offer antibiotics. Following is worth 1 pt each
What can be used as an alternative to the Centor critera?
FeverPAIN score
What values of the FeverPAIN score indicate likelihood of bacterial tonsillitis
Management of tonsillitis that is likely viral?
Educate patients and give safety net advice
Advise simple analgesia with paracetamol and ibuprofen to control pain and fever

List 4 instances where we may consider prescribing antibiotics in tonsilitis?
