Mainland China has announced its first known monkeypox infection, in an individual who arrived from abroad.
The Chinese city of Chongqing reported a case of the virus on Friday amid the recent global outbreak.
China's special administrative region of Hong Kong has previously reported a monkeypox infection.
The transmission risk is low as the individual was put in quarantine upon arrival in Chongqing, the municipal health commission said in a statement.
All close contacts have been isolated and are under medical observation.
The person concerned entered Chongqing city in transit from abroad and showed symptoms including a skin rash during their quarantine period for COVID-19, according to the statement.
Around 90 countries where monkeypox is not endemic have reported outbreaks of the viral disease, which the World Health Organisation has declared a global health emergency.
There have been more than 60,000 confirmed cases and some non-endemic countries have reported their first related deaths.
As of September 15, Australia had recorded 132 cases of the disease, the vast majority in NSW and Victoria.
The monkeypox virus, which is transmitted through close contact with infected people, animals or contaminated materials, usually causes symptoms similar to - but milder than - those of smallpox, including fever, headache and rashes.
