Group B Streptococcus Prevalence High Among Young Adults Living in Close Quarters

Strategic Insights

— 1 min read

Researchers have found a high prevalence of Group B Streptococcus (GBS) colonization among young adults living in a college dormitory. The study, published in Clinical Infectious Diseases, shows that 34% of women and 20% of men living in close quarters were colonized with GBS. The findings suggest that GBS is likely transmitted by intimate contact, but transmission modes may vary by colonization site.

Key Takeaways:

  • The prevalence of GBS colonization was high among young adults living in a college dormitory, with 34% of women and 20% of men being colonized.
  • Sexually experienced subjects had twice the colonization rates of sexually inexperienced participants.
  • The study found that only 10 of the 142 roommate pairs had roommates who were both colonized with GBS, and 20% of these pairs shared identical strains.
  • The transmission of GBS may vary by colonization site, and further large prospective studies are needed to understand the factors involved.
  • The study highlights the importance of understanding GBS transmission in young adults, particularly those living in close quarters.
  • The colonization rates were higher among women than men, with 34% of women being colonized compared to 20% of men.
  • The study's findings have implications for the prevention and treatment of GBS in young adults.

Statistics:

  • 241 women were tested for GBS colonization, with 34% (82 women) being colonized.
  • 211 men were tested for GBS colonization, with 20% (42 men) being colonized.
  • Only 10 of the 142 roommate pairs had roommates who were both colonized with GBS.
  • 20% of roommate pairs with both roommates colonized shared identical strains.
  • The transmission rate was twice as high among sexually active individuals compared to those who were not sexually active.
  • The study population consisted of 452 individuals (241 women and 211 men).
