This is an updated version of the interim guidance for surveillance, case investigation and contact-tracing for mpox published on 22 December 2022. It applies to all countries. The document has been revised to align with the recommended reporting procedures following the issuance of the WHO Standing recommendations for mpox and includes the most recent information available on mpox. The document contains a new chapter on mpox reinfection and provides case definitions for suspected, probable and confirmed reinfection. It has also been adapted to include more considerations relevant to endemic contexts in the African region. The overall goal of surveillance, case investigation and contact tracing for mpox is to detect new outbreaks and stop transmission, protect people at risk in endemic and new settings, and make progress towards elimination of human-to-human transmission of mpox. |
