TEL AVIV: Israel warned on Tuesday against travel to the United States and other countries and said it would tighten quarantine measures for inbound travelers as part of efforts to slow the spread of the coronavirus Delta variant.
New Covid-19 cases have surged in highly-vaccinated Israel since the emergence of the highly contagious Delta variant, prompting health officials this week to begin administering vaccine booster shots to people over 60.
It also began mandating isolation for returning travelers - including those vaccinated or recovered from the virus - from countries deemed "red", indicating a rapid spread of the disease.
