Hello Erdoan, Katrina from World Nomads here.
If you're a Canadian or USA residents/citizen, then our plans unfortunately can not cover you to go to Cuba.
For residents of other countries, as long as it's safe to go there, and there are no government warnings advising you against travel to, or in particular parts of Cuba, you can stay covered on the travel insurance plans we offer.
If you have a specific question about the plans or coverage, please contact our customer service team - http://worldnomads.com/contactus.aspx
