A new federal executive order expands the list of illnesses for which you could be detained, isolated, and treated against your will if you are entering the US or traveling between states—even if you are completely healthy. Some states have similar or worse laws that would even allow entry into your home.
President Obama has signed an executive order expanding the list of illnesses that could result in forced detention, isolation, and quarantine for anyone exposed, even if they are not sick. It updates a Bush-era executive order, adding “severe acute respiratory syndromes” except for influenza to the list of detainable communicable diseases.
The Public Health Service Act allows the government to apprehend and detain individuals based on communicable diseases named in the Act, or named by presidential executive orders. Executive orders do not have to get congressional approval.
