- CDC Flags First Case of MPXV in US
On November 18, the Centers for Disease Control and Prevention (CDC) issued a health alert with information about the first case of clade I mpox (MPXV) diagnosed in the United States. The alert includes recommendations to clinicians about preventing, diagnosing, treating, and reporting MPXV cases. There have been no changes to CDC clinical guidance on MPXV since HAN Health Update 516.
Clinicians should follow specimen collection guidelines (including collecting two swabs per 2-3 lesions) to ensure specimen availability for clade-specific testing, the CDC said. This testing will help distinguish cases that are part of the ongoing clade II mpox global outbreak from those that are part of this clade I outbreak. The CDC recommends sending clinical specimens to a laboratory that can perform clade-specific MPXV testing as quickly as possible.
