Due to the pandemic, it is not practical for people from the U.S. to travel to Cuba, although other countries, such as the UK, list Cuba among the nations safe enough for people to visit. Read the latest UK travel advice on Cuba.  For example, even the U.S. medical students back in the U.S. for rotations during their summer break will have to return for a 14-day quarantine, since they are coming from the highly infected U.S., and Cuba has canceled all U.S. solidarity trips for 2020.  Cuba has implemented a 3 phase process, and so far opened up certain parts of the country to some foreign tourists, such as from Canada to the resort areas; they will all be tested (for free) but otherwise not subject to quarantines, see https://www.traveloffpath.com/cuba-reopening-for-tourism-everything-you-need-to-know/
