The US Department of State issued a level-four travel warning for Venezuela on March 14, 2019, to tell Americans "do not travel" to the chaos-stricken country, and that all Americans in the country should leave. It's the highest travel warning that the department issues.

The advisory pointed to "crime, civil unrest, poor health infrastructure, and arbitrary arrest and detention of US citizens."

The announcement aligns with a top-level warning that the Centers for Disease Control and Prevention issued in May 2018. That warning said outbreaks of measles, malaria, diphtheria, and other infectious diseases are contributing to "an increasing humanitarian crisis affecting much of the country."

Political rallies and demonstrations occur with little notice, the warning said. And these rallies attract a strong police response with "tear gas, pepper spray, water cannons, and rubber bullets against participants and occasionally devolve into looting and vandalism."

"Security forces have arbitrarily detained US citizens for long periods," the warning said. "The US Department of State may not be notified of the detention of a US citizen, and consular access to detainees may be denied or severely delayed."

After this warning was issued, American Airlines announced on March 15, 2019, that they would suspend flights into Caracas and Maracaibo. "Our corporate security team has a collaborative partnership with all of our union leaders and we will continue to do so to evaluate the situation in Venezuela," the airline said in a statement.
