Travel insurance comparison website Squaremouth reported that there was an 18% increase in the number of travelers who bought insurance in 2016 over the prior year.

Squaremouth largely attributed that increase to world events.

"Over the past year, we saw the impact of concerns about terrorism and Zika virus on traveler behavior, but we did not see Americans stop traveling," spokeswoman Rachael Taft said in a statement. "More Americans sought travel insurance for their trips in 2016, and many chose to visit destinations closer to home."

The top destination for U.S. travelers in 2016 was the United States, followed by Mexico, Italy, Canada, France, the U.K., Spain, the Bahamas, Germany and Israel.

According to Squaremouth, the U.S., Mexico and Italy remained in the top three spots for U.S. travelers in 2016, while Canada overtook France and the U.K. to clinch the No. 4 spot.

Squaremouth reported decreases in travelers to Puerto Rico, the U.S. Virgin Islands, the Dominican Republic and Aruba in 2016, which it attributed to Zika virus fear. Travel to Cuba increased 148%.

In the past year, the number of travelers searching for coverage for terrorism on Squaremouth more than doubled, according to the site. Travelers also wanted the option to cancel for reasons that aren't typically covered, like Zika or potential terrorism, reflected in an 11% increase in travelers that purchased cancel-for-any-reason insurance. There was a 70% increase in customers that were seeking inclement weather coverage.
