A senior official of the World Health Organization (WHO) has urged countries to take science-based precautionary COVID-19 entry restrictions that are proportionate and non-discriminatory.
Hans Kluge, WHO's regional director for Europe, made the appeal at a press conference here on Tuesday.
"For those countries in our region introducing precautionary travel measures at this time, we are calling for such to be rooted in science, to be proportionate and non-discriminatory," Kluge said.
