Key Points

Mpox

• Confirmed and suspected cases of Mpox are currently being reported in Madagascar. In the event of any clinical suspicion (a person presenting with a rash or one or more ulcerations of the genital, anal, or oral mucosa suggestive of Mpox, whether isolated or preceded or accompanied by a perceived or measured fever (>38°C), lymphadenopathy, or odynophagia), the ARS La Réunion must be notified as soon as possible at: ars-reunion-signal@ars.sante.fr, particularly in cases of return from Madagascar or contact with individuals returning from Madagascar. These suspected cases will be discussed with an infectious disease specialist, and if confirmed, a request for biological confirmation with specimen collection at the University Hospital (South and North campuses) will be ordered. Affected patients must not go to private laboratories.
