First Case Report of Cystic Echinococcosis Caused by G7 Genotype Echinococcus intermedius Confirmed by Genetic Sequencing - Southern China, December 2023.

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Echinococcosis exhibits a global distribution. In China, the primary endemic area is the northwest region. In December 2023, we documented a case of echinococcosis in an individual lacking any travel or residential history in endemic regions.

WHAT IS ADDED BY THIS REPORT?: This is the first laboratory-confirmed case of hepatic echinococcosis reported in Guangdong Province, associated with the G7 genotype of Echinococcus granulosus (E. granulosus). The most probable mode of transmission is a local infection resulting from E. granulosus introduced from endemic regions.

WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: As the circulation of agricultural products increases, it is essential to enhance the quarantine and management of livestock from epidemic areas to prevent and control the spread of echinococcosis to non-epidemic regions.
