(CNN) — The US Centers for Disease Control and Prevention added eight destinations to its highest-risk category for travel on Monday, including the world’s No. 2 most-visited nation before the pandemic started.

In its weekly update of Covid-19 travel advisories, the CDC advised against travel to tourist favorite Spain at this time. In 2019, Spain received more international visitors than nearly every other nation in the world, except France, according to figures from the UN’s World Tourism Organization.
