Thank you for your query on Healthcare Magic.
Cocci are bacteria which are called Group B streptococci which are associated with the early neonatal infections leading to sepsis
in newborns due to their vulnerability to infections because of low immunity.
If the tests or blood cultures are positive for it, the child will require appropriate antibiotic therapy for 1 week to 10 days to treat the infection.
Nothing to worry and this condition is a common problem in newborns and can be treated with medication.
Therefore I advise you to discuss with the treating doctor and clarify your apprehension.
Hope I have answered your query.
