Israel's interior ministry said Saturday it was broadening border restrictions to bar entry to anyone who has visited China in the past two weeks.
On Thursday the country barred all flights from China over concern about the coronavirus epidemic, amid growing fears of global contagion.
Saturday's interior ministry announcement went further, blocking passengers from third countries if they had been in China at any time in the past 14 days.
The ban covers air and sea ports as well as land crossings from neighbouring Jordan and Egypt.

There have been no recorded incidents of coronavirus in Israel yet, but the health ministry said Wednesday it was "a matter of time".
