I could not find any US proclamation regarding what to do after international travel, except from certain countries, of which Jamaica is not one.

Here is what is on the CDC webpage for International Travelers:

"Stay home for 14 days from the time you returned home from international travel.
During this 14-day period, take these steps to monitor your health and practice social distancing:

Take your temperature with a thermometer two times a day and monitor for fever. Also watch for cough or trouble breathing. Use this temperature log to monitor your temperature.

Stay home and avoid contact with others. Do not go to work or school.
Do not take public transportation, taxis, or ride-shares.
Keep your distance from others (about 6 feet or 2 meters)."
