St Kitts and Nevis shut its borders to commercial flights, ships and yachts on 25 March "to safeguard citizens, residents and visitors alike".

Nationals and residents who were overseas when the measures were introduced have been required to remain offshore until the restrictions are lifted.

Island authorities set up a task force to ensure all businesses adhere to the measures, which had worked with hotels and restaurants to ensure they committed to the effort.

The Nevis Tourism Authority (NTA) said a health app had helped authorities track people with symptoms, mitigating any further risks of the infection spreading.

Monitoring efforts are ongoing, overseen by the island’s health service, and according to the NTA, there are just three confirmed ongoing cases in the federation.

Jadine Yarde, NTA chief executive, said: “The decision to close our borders did not come without serious consideration as tourism is hugely important to Nevis.

"However, our highest priority is the health and wellbeing of our people. This has paid off and we are now Covid free. We wish the best for all those interested in Nevis and we hope to see you when we can finally accept visitors again.”

To encourage people to return, the NTA is calling on past visitors to share their pictures and memories from their time on the island through social media under the hashtag #SeeYouSoonNevis.
