The charity is calling for guidelines to be updated after it was found the number of babies being infected with group B strep is increasing.
The RCOG published the prevention guidelines in 2003, with the view to reduce the number of babies being infected by 50-60%.
However, Public Health England figures show the number of infections in babies has increased by 32% since the guidelines were introduced.
Group B Strep Support is now calling for guidelines to be updated after figures prove the current guidelines have failed.
Chief Executive of GBS Support, Jane Plumb MBE said: “The current strategy has clearly failed. We welcome the recommendation to update the national guidelines – this needs to be addressed urgently.
“The latest reports show that the rate of group B strep infections in new born babies in the UK has continued to rise throughout the last decade.
“When updating the guideline, the key focus must be on a) establishing why the rate of GBS infection is continuing to rise despite a well-established prevention strategy intended to do precisely the opposite, and b) what changes need to be made to reverse this rise.”
The charity has said that it welcomes the news that 40% of Midwifery Led Units offer care to women who have group B Strep carriage.
However, almost 10% of these units do not have the antibiotics used in labour, recommended by RCOG and NICE.
Group B strep infections are life-threatening to new born babies, causing sepsis, meningitis and pneumonia.
Currently in the UK, one baby develops the infection every day, with one baby dying from infection each week.
