Governor DeSantis announced that anyone traveling from New York, New Jersey, Connecticut or Louisiana must self-quarantine for 14 days or for as long they stay in Florida if it is shorter than 14 days. This measure does not apply for people working in activities considered essential such as healthcare or the military. This kind of measures are being adopted by several other states like Alaska, Arkansas, Connecticut, Hawaii, Idaho, etc. Some states apply it to all travelers and some others to travelers from specific locations.
