The head of the World Health Organization (WHO) has expressed concern at the number of coronavirus cases with no clear link to China or other confirmed cases.
Dr Tedros Adhanom Ghebreyesus said the window of opportunity to contain the virus was “narrowing”.
Chinese health authorities reported a decrease in deaths and new cases of the coronavirus on Saturday.
But cases are on the rise in South Korea, Italy, Iran and other countries.
Outside China, more than 1,200 cases of the virus have been confirmed in 26 countries and there have been eight deaths, the WHO says.
Dr Tedros said the number of coronavirus cases outside China was “relatively small” but the pattern of infection was worrying.
“We are concerned about the number of cases with no clear epidemiological link, such as travel history to or contact with a confirmed case,” he said.
The new deaths and infections in Iran were “very concerning”, he said.
But he insisted that the measures China and other countries had put in place meant there was still a “fighting chance” of stopping further spread and called on countries to put more resources into preparing for possible outbreaks.
