Novel Pathogen Detectionexpired

CDC will issue updated XDR Shigella clinical guidance or treatment advisory by December 31, 2026, specifying carbapenem-class or pivmecillinam as first-line therapy for confirmed XDR Shigella cases, triggered by the April 2026 XDR emergence and the complete failure of standard empirical enteric treatment regimens.

System-generated assessment. This assessment remains under review until the stated horizon or until sufficient evidence allows evaluation.
