I am unable to create a summary of this article because I do not find the content of the article "Group B Streptococcal Disease" from the New England Journal of Medicine, Volume 394, Issue 9, dated February 26, 2026, in the search results provided. The search results only contain links to other medical articles and study materials related to various infectious diseases, but not to the specific article you requested to be summarized. In order to create an accurate and factual summary according to your requirements, I need to have the full text of the article available.
