Thank you for your query,
How this recurrent streptococcal infection
in your child has been diagnosed?
Is this being diagnosed on depending the throat culture
or any blood for its antibody test?
Please provide the information so that I can advise you properly.
As antibody titres will persist for long time in the blood , we cant take these positive results for recurrence of the infection.
Discuss with your Pediatrician
regarding this issue and he will advise you the steps to resolve the problem.
Hope i have answered your query.
