Requesting travelers to provide PCR tests to enter other countries once vaccination drives are well underway "is a step back," Secretary-General of the World Tourism Organization (UNWTO) Zurab Pololikashvili told Efe in an interview Thursday.

With a new flurry of measures being rolled out across Europe as the Omicron variant continues to drive infection rates up, the UNWTO chief expressed concern over the growing number of countries, including Italy and the United Kingdom, that are demanding PCR tests for foreign travelers.

"My message will be to be united, to be united will give us more possibilities to restart as fast as possible and millions of jobs are still at risk. Private companies, families and people who are working in the tourism industry are still suffering,” Pololikashvili said.
