Before playing England, West Indies will host Ireland in three one-day internationals and a one-off T20 international between January 8 and 16 in Jamaica.
"We have tried to maintain the general make-up of the squads from the Pakistan tour before Christmas, with the captain and some senior players coming back in," said head coach Phil Simmons.
"Covid-19 has also played a part in the final make-up of the squad. The challenges in the next couple months are getting the young players in both squads to not only improve on their skills but maintain the attitude and desire we saw in Pakistan.
"We do need to start the year on a high. And we know both Ireland and England have very good teams, so we expect a very strong challenge as we look improve our chances of automatic qualification for the ICC Cricket World Cup in 2023 and building the T20 team for the ICC T20 World Cup in 2022."
West Indies T20 squad to face Ireland and England: Kieron Pollard (captain), Nicholas Pooran (vice captain), Fabian Allen (England only), Darren Bravo (England only), Roston Chase, Sheldon Cottrell, Dominic Drakes, Shai Hope, Akel Hosein, Jason Holder, Brandon King, Kyle Mayers, Rovman Powell, Romario Shepherd, Odean Smith, Hayden Walsh Jr.
Covid-19 reserves: Jayden Seales, Alzarri Joseph, Devon Thomas.
