49 CFR 39.31 - May PVOs limit access to transportation or use of a vessel on the basis that a passenger has a communicable disease?
(1) Refuse to provide transportation or use of a vessel to the passenger;
(4) Require the passenger to provide a medical certificate.
(b) You may take actions listed in paragraph (a) of this section only if either or both of the conditions listed in paragraphs (b)(1) and (2) of this section are met. The action you take must be the least restrictive from the point of view of the passenger, consistent with protecting the health of other passengers.
(1) U.S. or international public health authorities (e.g., the Centers for Disease Control, Public Health Service, World Health Organization) have determined that persons with a particular condition should not be permitted to travel or should travel only under conditions specified by the public health authorities;
(2) An individual has a condition that is both readily transmissible by casual contact in the context of traveling on or using a passenger vessel and has serious health consequences.
(c) Any action of those listed in paragraph (a) of this section that you take under paragraph (b) of this section must be the least drastic action you can take to protect the health of other passengers. For example, if you can protect the health of other passenger by imposing a condition on the transportation of a passenger with a communicable disease (e.g., limiting the passenger's access to certain facilities on the vessel for a period of time), you cannot totally deny transportation on the vessel.
(d) For purposes of paragraph (a)(4) of this section, a medical certificate is a written statement from the passenger's physician saying that the passenger's disease or infection would not, under the present conditions in the particular passenger's case, be readily communicable to other persons by casual contact during the normal course of the passenger's transportation or use of the vessel. Such a medical certificate must state any conditions or precautions that would have to be observed to prevent the transmission of the disease or infection to other persons in the normal course of the passenger's transportation on or use of the vessel. It must be sufficiently recent to pertain directly to the communicable disease presented by the passenger at the time the passenger seeks to board the vessel.
(e) If your action under this section results in the postponement of a passenger's transportation or use of the vessel, you must permit the passenger to travel or use the vessel at a later available time (up to one year from the date of the postponed trip or use of the vessel) at the cost that would have applied to the passenger's originally scheduled trip or use of the vessel without penalty or, at the passenger's discretion, provide a refund for any unused transportation or use of the vessel. If there is no available reservation within one year, you must provide a refund.
(f) If you take any action under this section that restricts a passenger's transportation or use of the vessel, you must, on the passenger's request, provide a written explanation within 10 days of the request.
