That Worldwide Caution for American travelers comes just as foodborne illnesses and human health concerns largely faded after the pandemic 

The U.S. caution against foreign travel was issued after the Oct. 7 massacre of Israeli citizens and numerous visitors in murders not exceeded since the Third Reich.

“Due to increased tensions in various locations around the world, the potential for terrorist attacks, demonstrations or violent actions against U.S. citizens and interests, the Department of State advises U.S. citizens overseas to exercise increased caution.”

The State Department comes just as World Health was against inviting travelers to hit the road, wher they’ve been since 2022.

That’s because currently, there are no Travel Health Notices for either top health warnings of Level 3 or Level 4 from the federal Centers for Disease Control and Prevention (CDC).   

That’s a big improvement from a couple of years ago when the pandemic had CDC putting up red lights all over the globe. The CDC system warns against all travel in Level 4 countries and cautions about nonessential travel in Level 3 countries.  

But no countries are currently getting the Level 3 or 4 treatment, meaning the world is open from a human health perspective.

CDC has Level 2 travel issue notices issued for several counties, which call for enhanced precautions.  A Level 2 Travel Health Notice may include 1) a disease outbreak (higher number of expected cases) in a country or region; 2) sporadic cases of a disease in an unusual or new geographic location; 3) natural and human-made disasters with severe environmental health risks, or infrastructure damage that would limit healthcare services availability; and 4) mass gathering events that can lead to disease outbreaks. 

Here is wher Enhanced Precautions are called for:
