This is the original expert.
That figure is quoted by sources such as web MD and wickipedia and other popular sites.
However, I am a clinician of over 20 years experience, and antibiotics do not always work that quickly.
You need to make sure you are symptom free.
It takes about 6 doses [a few days] of antibiotics to make sure your treatment is at a steady state.
Symptoms often abate starting at about 48 hours.
Some strains are resistant to antibiotics, in which case this would not happen.
Some strep avoid antibiotics
Some infections can have a peritonsilar abscess or other problems that delay resolution.
For this reasons, I tell my patients to wait up to 7 days, depending on their symptoms, before intimate oral contact.
Make sure you wait at least a few days and that your symptoms are clearly improving.
Be safe, not sorry.
