Sexually transmitted shigella cases rising in study data

A study found sexually transmitted cases of the bacterial gut infection shigella are increasing. The research tracked transmission patterns and identified a rise in cases linked to sexual contact.

Study findings Researchers documented the spread across multiple regions and noted higher rates among certain populations. The same study recorded clusters of infection that health agencies linked to sexual networks rather than food or water sources.

Public health response Officials stated the pattern represents a distinct public health threat. Health agencies said they are reviewing surveillance methods to improve detection of sexually transmitted shigella cases.
