Travelers hailing to the District from 27 “high-risk” states are now required to quarantine for two weeks, according to a press release Monday.

Nonessential travelers entering the city from Arkansas, Arizona, Alabama, California, Delaware, Florida, Georgia, Idaho, Iowa, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, Nevada, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, South Carolina, Tennessee, Texas, Utah, Washington and Wisconsin must self-quarantine for 14 days, according to the release. States where the weekly average of daily COVID-19 cases exceeds 10 or more per 100,000 people are considered high risk, the release states.

Those entering the District for “essential activities” – like a job – or those returning home to the District should only leave their homes for essential activities for 14 days and self-monitor their symptoms, according to a release last week. Travel to and from Maryland and Virginia are exempt from the order, the release states.

The release adds that employees, universities and apartment buildings may require compliance with the order before permitting entrance to their properties.

Those in self-quarantine are required to remain in their residences or hotel rooms and are only permitted to attend medical appointments or to purchase food, according to the order. Individuals in self-quarantine are not permitted to have guests, the release states.

The list of states will be updated Aug. 10, and the order will remain in effect until Oct. 9 – the expected end of the public health emergency in D.C. – the release states.
