Three Irish players have tested positive for Covid-19 ahead of the team's scheduled journey from Florida to Jamaica on Friday.
Paul Stirling, Shane Getkate and George Dockrell all registered positive tests and the first two will partake in a mandatory 10-day quarantine. Dockrell, however, had tested positive prior to travelling to the USA and has a recovery certificate from that infection, and does not have to complete that isolation process.
Ireland are set to face the West Indies in a four-match schedule, including an T20 international, starting on 8 January and concluding on 16 January.
They have been based in Florida in recent weeks where they agreed to cancel their two One-Day Internationals with USA due to Covid-related concerns.
"It is a challenging time for all, but the players have responded very well to operating within the managed environment over the last two weeks," Richard Holdsworth, High Performance Director for Cricket Ireland said.
"A managed environment is different to a bio-bubble, and is an approach being used currently to try and find that balance between risk mitigation from the virus and impacts of sustained periods of isolation on the mental and physical health needs of players and staff.
"Part of this new approach is the ability to have several partners travel with the squad, however, these additional people are required to abide by the same testing and travel protocols as the players.
"However, the transmissibility of this latest strain of the virus has not spared us – nor indeed the USA squad nor the umpires in our recent series – and overnight three players have now tested positive."
