Abstract

Abstract In November 2025, a traveler from Cuba tested positive for chikungunya virus upon arrival to Mexico. The virus belonged to the East-Central-South-African lineage, clustering with a clade prevalent in Brazil. Ten years after the last chikungunya epidemic in Mexico, strengthened surveillance is required to anticipate transmission of this emergent lineage.
