VIENNA (Reuters) - The World Health Organization (WHO) is concerned about the number of coronavirus cases with no clear epidemiological link, although the total number of cases outside China remains relatively small, its director general said on Saturday.

Cases with no clear link include those with no travel history to China or contact with a confirmed case, Tedros Adhanom Ghebreyesus said on Twitter.
