The United States Department of State issued the advisory for Dominica and other Caribbean islands, including Barbados, on Thursday.
The advisory urged US citizens to reconsider travel to Dominica due to health and safety measures and COVID-related conditions and to exercise increased caution due to civil unrest.
It said travelers to Dominica may experience border closures, airport closures, travel prohibitions, stay at home orders, business closures, and other emergency conditions due to COVID-19.
Speaking on his Anou Palay programme on Sunday, Mr. Skerrit said the US move was unnecessary and his Government had written to the State Department on the matter.
The US topped 5 million cases of coronavirus early Sunday.
